I worked for a contractor crew for a year once between bigger jobs. We did hydrogen compressor rebuilds in refineries that required a piss test to work in those enviroments.The contractor gave us the sample bottles and told us to bring them back the next day and make danged sure they were clean of drugs. Half the crew were pot heads and could no way pass that test, but they all showed up clean when the results came back.When it comes to welding high pressure lines that may contain gasses or fluids that can kill hundreds if not thousands of people with a faulty weld, I'm sure you can see why the state wants to know as a regulatory agency that you can actually weld and aren't just a dobber that claims they can weld which some contractors would hire. If you're as good a welder as I'm sure you are, there should be zero issues with doing a weld test that the state requires to satisfy their safety concerns. It's just one more weld. I've watched a lot of welders working in the boiler at our Power Plant before I retired. Amazing skills for that high pressure work with two guys working on one pipe. One would start the weld on his side of the pipe. On the other side the other welder would pick up the arc halfway around and finish the weld so it would be continuous. Xray after.</blockquote>
