welded cast alum. with fluxcore

[Millright52]

Hey guys, I've been told that you can't weld aluminum with flux core wire.welded some yesterday with my Hobart E-Z 125. Set on 90 amps. Anyone ever heard of doing that? What else could I weld with it?

[big mike]

I've never heard of aluminum flux cored wire.

it is dependant on what the flux core is but yes there is alum flux core wire. HOWEVER it is for brazing/soldering applications not "mig" welding, as far as i know/ can find.

[elvis]

What kind of wire? Just because you were able to strike an arc and get a bright light doesn't mean it was a good weld...

I never knew anything besides for tig for cast aluminum.

it held somehow

Used regular flux core .30 wire, don't remember specs. It hel up to a snow quench while it was red hot. And withstood impacts that the casting could , no break, no fail. By all means it was not a pretty weld.

How do you get aluminum red hot?

This thread makes my brain hurt. Please put down the whip and step away before someone gets hurt

Are you sure this is cast "aluminum" and not cast "iron" , "steel" or ductile iron?

I'll refraze my previous statement. I only know of tig for small cast aluminum repairs. I have used a spool gun before but that would have taken me 3 days to tig vs 6 hours mig.

Yeah for sure it's aluminum. It was a broken snow cleat for roofing. Don't know how or why it welded with flux core gas less wire, but it did. As far as getting red hot, 90 amps and a few minutes welding pretty much got it there. It sure befuzzles me too.

Yeah mike, just caught what I said . Not "red hot". Lol. Way too hot to touch.
