5 steps to code welding success Part 4

     Metal fabrication has a lot of moving parts. The more complex a project becomes, the more moving parts it has, incorporating a variety of skilled trades and professionals: mechanical, coating, designers, engineers, architects. The number of variables that need to be accounted for to achieve a successful, structurally sound, and safe fabrication project can be truly mind-boggling.

 

Qualify the Welder per the Code

 

   Cameron sees similar welder qualification problems when it comes to material thickness. If a welder is qualified per AWS D1.1, that’s great—but it also means that he or she can weld only a specific thickness range, starting at 0.125 in. “Then you walk into the weld shop and see those welders [performing code-level work] on 12- and 16-gauge sheet metal.”
 
   If welders need to perform code-level welding on thinner material, “they need to be qualified to AWS D1.3, which is the structural code for sheet metal.” Cameron added that, ideally, this should be spelled out in the contract documents.
