Exactly. My experience has been that many incoming welders simply don't know the code with regard to what is acceptable and what is not, and they just need to be shown. A few of them know, most of them don't. Years ago this actually surprised me... that supposedly structural welders came in for a test and didn't know what a WPS was, didn't know the tolerances for porosity, undercut, undersize weld, etc., or didn't know how to use a fillet gage. All very basic things that a structural welder should know. I've since gotten used to it and have taken the time to help them out and shown them myself. I firmly believe that quality should be built into the product, not inspected into it, and that's what I continue to push for. If they don't know, I show them, and then hold them accountable afterwards.
