Do Welding Certificates Expire in South Africa? Validity & Renewal
Updated: Sep 30
Do welding certificates expire in South Africa? A welding certificate issued years ago may still be valid. But that does not necessarily mean it will be accepted for the welding job you want to perform today.
The answer depends on the certificate you hold, the welding process you were tested on, the applicable standard and whether you can demonstrate current competence.
For South African welders, employers and contractors, understanding these differences can prevent unnecessary training costs, unsuccessful job applications and problems during welding-quality audits.
Quick Answer: Do Welding Certificates Expire in South Africa?
There is no universal expiry date that applies to every welding certificate in South Africa.
A short-course completion certificate generally remains a record of the training you completed, although an employer may require evidence that your skills are current. A South African Red Seal or trade certificate does not expire.
Coded-welder qualifications are different. Depending on the governing standard, they may require documented welding continuity, six-month confirmation, periodic revalidation or a new qualification test.
For example, ISO 9606-1, AWS and ASME Section IX have specific requirements that should not be confused with one another.
The key distinction is that a certificate can remain genuine while no longer providing sufficient evidence for a particular welding job.
Before paying for refresher training or another welding test, establish which certificate you have, which process it covers and why it is no longer being accepted.
Welding Certificate Validity in South Africa: Comparison Table
Certificate or qualification | Does it expire? | What should you check? |
Welding short-course certificate | No universal national expiry period | Training outcome, issuer, employer acceptance and current skills |
Practical competency certificate | Depends on its terms and intended use | Assessment scope, issuer and any stated validity conditions |
Legacy SAQA unit-standard achievement | The recorded achievement is not erased when its registration ends | Statement of results, authenticity and current relevance |
QCTO occupational qualification | A registration end date does not automatically expire an earned qualification | Authenticity, qualification awarded and employer requirements |
Red Seal / trade certificate | The trade achievement does not expire | Authenticity and any additional job-specific requirements |
ISO 9606-1 welder qualification | Subject to confirmation and the selected revalidation route | Six-month confirmation, supporting evidence and revalidation conditions |
AWS Certified Welder | Requires maintenance under the governing code | Process continuity, maintenance forms and certification status |
ASME Section IX welder qualification | Can expire when required process continuity is lost | Process-specific continuity and qualification records |
Employer or project approval | May be restricted to an employer, project or contract | Client requirements, WPS, approval scope and applicable code |
The table is a starting point, not a substitute for examining the original qualification record and the standard governing the work.
A welder should never assume that a Red Seal replaces coded welding, that a training certificate qualifies every welding position or that every coding needs a complete retest after six months.
Check Your Welding Certificate Before Paying for Another Course
Not sure whether your welding certificate is still valid, whether your coding has lapsed or whether you need a new qualification test?
Get Swift Skills Academy's free Welding Certificate Validity & Continuity Audit Checklist — South Africa.
The practical workbook is designed to help welders and employers identify:
The type of certificate or qualification held.
Which welding process and qualification range it covers.
Whether continuity evidence is available.
Which code-specific requirements need to be checked.
What to do when records are missing or a qualification is no longer accepted.
Whether practical training, assessment guidance or a formal qualification route may be relevant.
Why Certificate Validity and Current Welding Competence Are Different
Welding qualifications serve different purposes.
A training certificate records learning or assessment. A trade certificate recognises occupational achievement. A coded-welder qualification demonstrates performance within a defined technical range.
An employer may need evidence of all three, depending on the work.
Consider a welder who completed a MIG welding course several years ago. The course certificate can remain a genuine record of that training, but it does not automatically establish that the welder can now perform a demanding pipe-welding job.
Likewise, a Red Seal artisan may hold permanent trade recognition but still require current, process-specific qualification testing for a particular project.
Three questions must be considered separately:
Is the original document genuine?
Does the qualification remain valid under its governing requirements?
Does its scope meet the requirements of the proposed work?
A positive answer to the first question does not automatically answer the other two.
Do Short Welding-Course Certificates Expire?
There is no single South African rule stating that every short welding-course certificate expires after one, two or three years.
A course certificate normally records what the learner completed or achieved at a particular time.
However, the wording and outcome of the particular programme matter. Where a certificate includes defined conditions or validity requirements, those conditions should be checked.
Employers may also require evidence of recent welding experience, a practical test or additional training.
Someone who completed basic Stick welding years ago may not need to repeat the entire course. If they have continued welding successfully, appropriate evidence or assessment may demonstrate their current ability.
On the other hand, a learner who has not welded for several years may benefit from refresher training before attempting a demanding qualification test.
The correct decision depends on the learner's actual skills and the required outcome.
Does a Training Certificate Make You a Coded Welder?
Not automatically.
A welding course and a coded-welder qualification test have different purposes.
A practical welding course develops skills such as machine setup, joint preparation, welding positions, process control and defect prevention.
A coded-welder qualification is based on successful testing under a specified welding code or standard.
The qualification identifies the range within which the welder is qualified, subject to the requirements of that standard.
A learner should therefore confirm whether a quotation covers training, preparation, qualification testing, external assessment and any associated documentation.
Do Coded-Welder Certificates Expire in South Africa?
Yes, a coded-welder qualification can expire, lapse or require revalidation when the applicable standard's requirements are not met.
There is no single expiry rule covering every coded-welder qualification.
Validity depends on factors such as the governing code, code edition, qualification route,
continuity evidence, employer or qualifying organisation, and any additional client requirements.
Three technical terms are especially important.
1. Continuity
Continuity is evidence that a welder has continued using the qualified welding process within the required period.
2. Confirmation
Confirmation is the documented acknowledgement required by a particular standard that its specified ongoing qualification conditions have been satisfied.
3. Revalidation
Revalidation is the process used to extend or renew a qualification according to the applicable standard's chosen route.
These requirements may operate together, but they are not interchangeable.
A six-month confirmation requirement does not necessarily mean the welder must repeat the original qualification test every six months.
Six-Month Welder Continuity: What It Actually Means
Six months is a common interval in major welding qualification systems. Its purpose is to establish that the welder has continued performing the relevant welding process.
For example, a welder may have separate qualifications for:
SMAW — Shielded Metal Arc Welding, commonly called Stick or Arc welding.
GMAW — Gas Metal Arc Welding, commonly associated with MIG/MAG.
GTAW — Gas Tungsten Arc Welding, commonly called TIG.
FCAW — Flux-Cored Arc Welding.
Under process-specific continuity rules, regular SMAW work does not automatically maintain a separate GTAW qualification.
The process used and the applicable code both matter.
A welder who last performed qualified TIG welding eight months ago should not assume that more recent Stick welding has kept the TIG qualification current.
That situation requires a review of the qualification record, continuity evidence and governing standard.
What Counts as Welding Continuity Evidence?
Depending on the standard and qualification scheme, appropriate supporting records may include production-weld records, job cards, welding logs, weld maps, inspection reports and employer or welding-coordinator confirmation.
A useful record should identify the welder, the process performed, the date of work and a traceable job or production reference.
Where relevant, the record should also identify the applicable Welding Procedure Specification (WPS) and the person authorised to confirm continuity.
The qualification scheme determines what constitutes acceptable evidence. A generic signature without credible supporting information may not satisfy an employer, examiner or auditor.
A Practical Continuity-Record Example
Record field | Information to capture |
Welder identification | Name and unique employee or welder number |
Qualified process | SMAW, GTAW, GMAW or other applicable process |
Qualification reference | Certificate or welder-performance qualification number |
Governing standard | Applicable code and edition |
Date process last used | Actual date of qualifying welding activity |
Work reference | Job card, weld map or production reference |
Supporting evidence | Relevant records and inspection results |
Confirmation | Authorised signatory, where required |
Next review | Date determined by the governing requirements |
Employers should maintain separate records for different processes where the qualification rules require them.
ISO 9606-1 Welder Qualification: Validity and Revalidation
ISO 9606-1 is a qualification-testing standard for welders performing fusion welding of steels.
It addresses welder performance and defines the conditions under which qualifications remain valid.
The standard distinguishes between six-month confirmation and the selected revalidation route. The certificate's actual provisions, applicable edition and contractual requirements must be checked.
The current ISO 9606-1:2012 edition was reviewed and confirmed by ISO in 2023.
Six-Month Confirmation Under ISO 9606-1
The welder's qualification must be confirmed at six-month intervals according to the standard's requirements.
This is not the same as automatically repeating the complete qualification test twice a year.
Confirmation depends on evidence that the relevant requirements have continued to be satisfied.
Three Revalidation Routes Under ISO 9606-1
ISO 9606-1 provides three revalidation arrangements, subject to their specified conditions.
Route | General requirement |
Three-year route | The welder is retested at three-year intervals |
Two-year route | Revalidation is supported by two qualifying welds from the final six months that have undergone the required testing, with records retained |
Continued-validity route | Continued validity is possible under specified conditions involving the same manufacturer, a verified ISO 3834-2 or ISO 3834-3 quality system and documented acceptable welding quality |
All three routes remain subject to the standard's applicable confirmation requirements.
The continued-validity route is not a general exemption from documentation, supervision or quality control. Its acceptance can also be restricted by the applicable application standard or regulatory requirements.
An employer must establish which revalidation arrangement actually applies to the qualification. The existence of three possible routes does not mean a welder can choose one retrospectively without satisfying its conditions.
For the detailed technical framework, consult ISO 9606-1 and TWI's explanation of ISO welder qualification and revalidation.
AWS Certified Welder: Does the Certification Expire?
The American Welding Society's Certified Welder programme uses maintenance requirements based on the code of acceptance governing the original test.
Under the normal six-month maintenance arrangement, the welder must submit the prescribed documentation confirming continued use of the welding process for which certification was awarded.
When the applicable requirements are satisfied and maintenance documentation is submitted on time, certification can remain active without a fixed lifetime limit.
Certain certifications have different maintenance intervals, so the actual code and programme requirements must be checked.
What Happens If AWS Maintenance Is Late?
AWS provides a 60-day administrative extension under its stated maintenance procedure.
Importantly, the certification is considered expired during that extension period. If the required documentation is accepted within the permitted period, AWS may renew it according to the programme's rules.
After the permitted period, retesting may be required.
This administrative arrangement belongs to the AWS programme and should not be presented as a universal rule for every welding qualification issued in South Africa.
See the AWS Certified Welder programme for its current requirements.
ASME Section IX: Does a Welder Qualification Expire After Six Months?
ASME Section IX is used for welding procedure and personnel qualification in applications where that code is specified.
Its welder-performance continuity provisions are process-specific.
Under the 2025 edition's QW-322 provisions, a welder's qualification for a process remains valid provided the required conditions are satisfied and no more than six months have passed since that process was last used.
The qualifying or participating organisation must confirm continuity as required by the code.
This means a welder does not necessarily require a completely new qualification test every six months. The relevant process must be used and continuity must be maintained and documented.
What Happens When ASME Continuity Is Lost?
Where qualification expires because the required process continuity was not maintained, ASME Section IX provides a renewal procedure.
Under the applicable conditions, a successful renewal test for that process can restore previous qualification ranges as provided by the code.
The exact test and documentation requirements must be established by the responsible qualifying organisation using the governing edition.
A loss of continuity should therefore trigger a technical review, not an automatic assumption that the welder must repeat every element of the original training programme.
Consult the applicable edition of ASME BPVC Section IX.
Do Red Seal and QCTO Welding Certificates Expire?
A South African Red Seal or trade certificate does not expire merely because a number of years have passed since the holder completed the trade test.
The Quality Council for Trades and Occupations is responsible for issuing trade certificates through the applicable national certification process.
QCTO's published verification guidance confirms that legacy trade certificates remain valid without an expiry date.
However, permanent artisan recognition does not automatically establish that the holder has maintained every specialist welding qualification.
A Red Seal artisan may still require current coded-welder qualifications, project-specific testing or evidence of recent practical competence.
Red Seal vs Coded Welding: The Important Difference
Red Seal / trade certificate | Coded-welder qualification |
Recognises qualification in the trade | Demonstrates performance within a defined technical qualification range |
Obtained through the applicable trade-test pathway | Obtained through testing under a specified welding standard |
Does not expire merely with age | Subject to the governing validity and continuity conditions |
Does not establish every process or project approval | Does not automatically confer Red Seal artisan status |
A welder can hold both, depending on the work and the qualification route completed.
Does an Old QCTO Occupational Certificate Become Invalid?
The registration status of an occupational qualification is different from the achievement recorded by an individual certificate.
For example, SAQA's record for Occupational Certificate: Welder, SAQA ID 94100, lists:
NQF Level 4.
373 credits.
Registration end date: 30 December 2025.
Last date for enrolment: 30 December 2026.
Last date for achievement: 30 December 2029.
These dates describe the qualification's registration and completion arrangements. They are not automatic expiry dates for a certificate already legitimately awarded to a learner.
Anyone considering enrolment must still verify the current qualification status, provider scope, registration arrangements and intended certification outcome.
See the official SAQA qualification record for the registered details.
Which Welding Pathway Do You Need?
Your next step depends on what you currently hold and the qualification outcome required.
I have a basic welding-course certificate.
If you need to develop another welding process, improve positional skills or prepare for more advanced work, explore Swift Skills Academy's welding programmes in Cape Town.
I am a coded welder, but my qualification may have lapsed.
Establish the governing standard, qualified process, last recorded welding activity and reason the qualification is no longer accepted.
For practical skills development and guidance on the appropriate preparation route, request a welding-programme callback.
I have years of welding experience but no Red Seal.
Experience may be relevant to an Artisan Recognition of Prior Learning pathway, subject to eligibility and formal assessment requirements.
Swift Skills Academy can assist with appropriate training and pathway guidance. Formal qualification testing, ARPL decisions, trade testing and certificate issuance must follow the requirements of the relevant authorised bodies.
Can an Employer Reject a Welding Certificate That Is Still Valid?
Yes. A qualification can remain valid under its governing standard while still being insufficient for a particular job.
The employer or project owner may require the welder to demonstrate competence within the scope of the work.
For example, a qualification may not cover the specified welding process, position, product type or relevant essential variables.
The employer may also require a project-specific demonstration, site approval, acceptable continuity records or compliance with contractual qualification requirements.
This does not automatically mean the original certificate was fraudulent or that the welder has lost every qualification.
It may mean the qualification does not satisfy the particular job.
Understanding the Qualification Range
A welder-performance qualification establishes a defined range under the applicable standard.
Depending on that standard, relevant variables can include:
Welding process.
Filler material classification or group.
Joint or weld type.
Welding position.
Plate or pipe configuration.
Deposited weld metal thickness.
Pipe diameter.
Backing arrangements.
Other code-specific essential variables.
The precise qualification range must be read from the actual record and interpreted using the governing standard.
A welder qualified in one process or configuration should not assume unrestricted qualification for every material, position or welding application.
How to Check Whether Your Welding Certificate Is Still Valid
Before paying for another welding course or qualification test, work through the following checks.
Step 1: Identify the Exact Document
Determine whether you hold a course completion certificate, competency record, statement of results, occupational certificate, trade certificate or welder-performance qualification.
If the document is a coded-welder qualification, establish the precise code or standard.
Step 2: Verify the Issuer
Check the identity of the issuing organisation and determine whether it was authorised to issue the specific document.
For a short-course certificate, contact the training provider where necessary.
For an official South African trade or occupational certificate, follow the appropriate verification process. QCTO explains which certificate types it can verify and when another issuing body should be approached.
Step 3: Confirm the Certificate Holder
Check the name, identification details and certificate reference.
The records should establish that the qualification belongs to the person presenting it.
Step 4: Check the Qualification Range
For coded welding, compare the qualification's scope with the work to be performed.
Establish the applicable process and other essential variables under the governing code.
Step 5: Review Continuity and Revalidation
Check the last qualifying welding activity, required confirmation dates, supporting production records and any prescribed revalidation requirements.
Do not assume that a qualification remains active simply because the physical certificate is undamaged.
Step 6: Compare It With the Job Specification
Review the project's WPS, contractual requirements, application standard and any client-specific acceptance conditions.
Determine whether the certificate and supporting records actually meet those requirements.
Step 7: Identify the Smallest Appropriate Corrective Action
Depending on the findings, the solution may involve obtaining missing records, arranging formal verification, refreshing practical skills or undertaking a qualification test.
Avoid paying for a complete beginner course before determining what is genuinely required.
What to Do If Your Coded-Welder Certificate Has Lapsed
A lapsed qualification does not automatically mean the welder must start their career again.
The correct response depends on why the qualification is no longer valid or accepted.
Situation | Appropriate next investigation |
Certificate is genuine but continuity documents are missing | Recover acceptable production and confirmation records |
Required process was not used during the permitted period | Determine the applicable renewal or requalification procedure |
ISO revalidation requirements were not met | Check the selected route and required testing with the responsible examiner or examining body |
AWS maintenance documentation was submitted late | Check the programme's current administrative extension and retesting requirements |
Qualification is outside the job's technical scope | Establish which additional qualification test is needed |
Welder's practical skills have deteriorated | Consider targeted refresher or gap training |
Certificate cannot be authenticated | Contact the responsible issuer or verification authority |
Do You Need to Repeat the Entire Welding Course?
Not necessarily.
An experienced welder may require targeted preparation for a particular process, position or qualification test rather than a complete foundation programme.
A beginner or someone who has been away from welding for a substantial period may benefit from broader practical development.
The best starting point is an accurate assessment of existing skills, documentary evidence and the specific work the welder intends to perform.
Employer Welding-Certificate Audit Checklist
For South African employers, construction contractors, fabrication workshops and maintenance teams, qualification management should form part of workforce-readiness and welding-quality controls.
An effective register should allow the organisation to identify who is qualified, what each qualification covers and when action is needed.
Before assigning a welder to controlled work, verify:
The person's identity and relevant qualification records.
The authenticity of the certificate and identity of the issuer.
The governing welding code and edition.
The qualified welding process and technical range.
The dates and supporting evidence required to maintain validity.
The applicable revalidation arrangement.
The WPS and client or project acceptance requirements.
Any outstanding training, testing or documentary gaps.
Maintain the supporting evidence in an accessible, controlled recordkeeping system.
What Should Trigger a Qualification Review?
Useful triggers include the arrival of a new welder, a new project, a change in welding process, work outside an existing qualification range, an approaching confirmation or revalidation deadline, and missing or disputed continuity records.
A change in employer or contractual qualification arrangements may also require a review.
For organisations working within an ISO 3834 quality-management framework, qualification records form part of a broader system of documented welding controls and quality assurance.
A training certificate alone should never be used as a substitute for all the records required by the applicable welding standard and project.
Frequently Asked Questions About Welding Certificate Expiry
1. Do welding certificates expire in South Africa?
There is no universal expiry period for every welding certificate. A short-course certificate records training or assessment, while a coded-welder qualification is subject to its governing standard. A South African trade certificate or Red Seal does not expire simply because time has passed.
2. How long is a coded-welder certificate valid?
Validity depends on the code, edition and qualification arrangement. Many systems require evidence of welding-process continuity within six months. ISO 9606-1 also provides specific revalidation arrangements. Check the original qualification record rather than assuming every coding expires after two years.
3. Does a coded welder need to retest every six months?
Not automatically. Six-month continuity or confirmation requirements are not necessarily six-month retesting requirements. A new test may become necessary when continuity is lost, revalidation conditions are not satisfied, technical scope changes or the governing requirements call for testing.
4. Does a Red Seal welding certificate expire?
No. South African trade recognition does not expire merely with age. A Red Seal artisan may still need current coded-welder qualifications or additional project-specific evidence for specialist welding work.
5. Can an old welding certificate still help me get a job?
Yes. It can establish that you completed the specified training or assessment. Employers may also require evidence of current competence, recent experience, appropriate coding or a practical entry test.
6. What happens if I have not welded for six months?
That depends on which process and qualification you hold, and which standard applies. Process-specific continuity requirements may have been affected. Review the qualification and the available records before assuming that it remains valid or that a complete new course is necessary.
7. Can I renew a coded-welder certificate without repeating the entire course?
Possibly. The governing code may provide an appropriate renewal or requalification procedure. The practical preparation required depends on the person's current ability and the qualification outcome needed. The authorised examiner or qualifying organisation must determine the applicable formal requirements.
8. Does an AWS Certified Welder certification expire if I miss the maintenance date?
AWS's programme provides an administrative extension under specified conditions, but the certification is considered expired during that extension. Check AWS's current maintenance and retesting rules for your particular certification.
9. Does the expiry of a SAQA qualification registration invalidate certificates already awarded?
No. A qualification's registration lifecycle and an individual's recorded achievement are separate matters. A legitimately earned qualification is not automatically cancelled because its registration period has ended.
10. Can a new employer require another welding test?
Yes. An employer or project may require appropriate proof that the welder can meet its technical and contractual requirements. An existing certificate may remain genuine and valid but not cover the specified work.

Final Word
A welding certificate's validity cannot be determined by its age alone.
A short-course certificate records a training achievement. A Red Seal recognises trade qualification. A coded-welder qualification demonstrates specific welding performance and remains subject to the conditions of its governing standard.
For welders, the most useful evidence is an authentic qualification supported by the correct scope, current records and demonstrated ability.
For employers, the objective is to establish that each person is appropriately qualified for the work they are being assigned.
Knowing the difference can prevent unnecessary training, avoid qualification disputes and support safer, more reliable welding work in South Africa.
