Re: Noob Welding Stainless to Mild?
 

Have to disagree. My Business partner built Farm Machinery for 3 years, Mild Steel to SS, MIG everyday, none of it cracks, Weld Temp and Wire Feeder is critical.

Whatever Engloid said- x2


Mr. 7 posts ought to come with proof if he wants to make claims about cracking.

When I was welding up my exhaust that had stainless in it and the tubing was just mild I the bead just melted into the stainless like butter while it took a little longer for it to do it with the mild. It welded alot nicer too and I was just using just normal fluxcore for mild steel and I got less splatter and just nicer beads.

i have had no problems welding mild to stainless with my mig. whenever i weld anything to stainless i prefer to use 309 ss wire and a tri mix gas ( 90% Helium-7.5% Argon-2.5% Carbon Dioxide) it has worked wonders for me so you should have no problems either, if you lack the confidence just go for it and you will see its not a big deal lol thats what i did and now im very confident mig'ing stainless :P

---- all that. whip out the flux welder :P

Ha ha ha...nah i just wasn't sure because I never welded dissimilar metals before and i know i read about possible problems...but i figured HMT guys new the truther since i've seen HF manis with steel ext gates welded to them

Re: Noob Welding Stainless to Mild?
 

Hell...steel is steel to me. It's either rusty or not rusty. I'll weld anything together if it's steel since all I have is hardcore OG fluxcore. I even got curious and desperate and tried AL and learned from that. It does make a cool popping sound though. 8)

I welded my bov flange to a piece of chromoly and that went fine....just used the shitty harbor freight welder and 75/25 mix gas.....welded that ---- no problem...
