what like 2205? had to purge weld a heap of 2205 tube a while ago, from memory it welded near identical to 316 but flowed nicer, it pulled like fuck when cooling though.Challenge for you, superduplex stainless.
all the welding I do for jet fuel pipelines is autogenous, as I am not very good with rod feed!...Aluminium is not too bad as it doesn't seem to melt into oblivion as quick.Welds ok but had to do gas pipelines. Any root cavity or reinforcement corroded. Autogenous welding saved the day. Km of pipe and thousands of welds.
nope, just a small 185 Everlast...gotta make sure you have heaps of meat to work with and lots of movement, as it likes to crack on cooling down if there is nowhere for it to go!Nice. Raw gas has some very nasty nasties in it that corrodes anything in its way. Autogenous ali? Interesting. Automatic machine?
