Also there are welders and then there are fabricator/welders two different things....I know a bloke who can weld like you won't believe, it's annoying how neat it is yet ask him to work to drawings, cut steel and make something and he is buggered...coding covers a set welding procedure not actually making something and usually the test piece is done by someone else and all you have to do is weld it up correctly...not easy but doable
