In the high-pressure world of South African heavy engineering—from pressure vessels to structural steel—the margin for error is exactly zero. When a weld fails, the cost isn't just a "do-over"; it’s a multi-million Rand liability, a lost contract, or worse, a catastrophic structural collapse. This is why the industry is no longer settling for "good" welders. They are demanding ISO 3834 Certified Welders . If your fabrication workshop isn't aligned with the ISO 3834 quality re
