One of the most common questions in welding is whether qualified or prequalified welding procedures are better. Both serve the same purpose — ensuring consistent, high-quality welds — but they achieve it in different ways. Qualified procedures are proven through destructive and nondestructive testing, while prequalified procedures skip testing if strict code requirements are followed. Prequalified procedures save time and money upfront, but qualified procedures can sometimes reduce weld volume and cut long-term fabrication costs. In this post, we explain both approaches, the requirements for each, and when to use one over the other to get the best results for your shop.
