    Default newb question-weld stainless to aluminized exhaust?

    Hi All,
    New here but have been reading for a long time, thanks for all I have already learned, but I got a question I need help with.

    I am getting ready to fab up the exhaust on my project car. I plan on using aluminized pipe for the majority of the project. I am grinding off the coating for the weld area. I have no problem migging the thin metal, I have done 80% of all of my other welding on sheetmetal. I am running 75/25 on a mig welder .23 wire - all there is good.

    The question I have is this: There is a section of stainless I need to attach the pipes to. Can I weld the stainless to the aluminized pipe using my mig and 75/25 mix? Or do I really need to get stainless wire and tri mix? The expense for that is a bit prohibitive for making only two welds.

    Will the stainless weld okay to the aluminized using 75/25 or maybe even flux core or am I asking for trouble?

    If the only problem will be that the weld will be susceptible to rust, I can live with that. I can use VHT exhaust paint or something else to treat the area. (the welds in the aluminized sections need to be coated anyway)

    Thanks for any input

    see if you can get a small spool of 309L ss dual sheild wire. your 75/25 should work ok. some wires will recomend CO2 but for what your doing I don't think you'll have any problems.

    Default Portable Welder

    The pipe that yor welding is steel pipe with a coating and your welding it to stainless.

    I say just weld it with your ER70-S6 wire.

    309L dual sheild is a flux cored wire that also requires gas sheilding, but portable is probably correct, your er70s should hold fine for what you doing.
