after i got out of the Airforce i took a metallurgy and welding course and took tig mig heliarc dc ac, welding all kinds of metal welding stainless brass bronze aluminum cast iron steel butt welds etc.
my favorite was dc reverse tig mig and especially gas welding oxygen acetylene .when yo do stick welding you have to stress relieve each gas weld or it will crack adjacent to the weld you made!ido welding for a living wouldn't want to do welding for a living. but have seen to many welds fail because they were not stress relieved!
