I'm more on Stan's side of the fence on this. I have welded stainless schedule pipe in coal fired power plants-- Not the hazard as per: 3 Mile Island, Chernobyl, and the movie "The China Syndrome"-- but I have seen cases of "fudged" weld X-rays-- each qualified weldor uses a code stamp usually related to his SS or payroll number-- so the X-ray lads can tell which one ran the passes being examined--
But welding is more than fabrication-- one good example comes to mind-- a Quarry or gravel pit-- Lincoln makes both a rod and a interflux core wire with heavy manganese-- code name is "Abrasoweld" if memory serves.
The life of scoops, blades, and other steel components used in such industries, and others- a backhoe shovel, or a clam-shell- can be extended a great deal by a build-up weld bead on the leading edge-- In my lexicon, that isn't broken, then fix-it welding, that is "preventative maintenance" in spades-
