Can stainless steel be welded with a flux core? I know stainless wire only comes in regular MIG wire and not flux core. What would happen if i welded with the mild steel flux core wire?

 

it would probably weld, but it would suck and probably crack.
get some gas....

 

It will work but it will look like poo and rust. Waaaaaaay back in the day I used to slap on stainless muffler with a fluxcore all the time

What about the strength of it?

 

I welded my brothers muffler on in about.....I'd say late 99. The car was sold in 05 and it was still stuck on there

 

I've been using flux core for all of my exhaust related stuff and yes it's strong, and it will eventually rust, but I've been using High Temp Clear coat spray to protect against the rust and It's been working so far. Yes it's strong, and will weld SS just fine, but It will look like rabbit poop, unless you've had practice making nice mig welds.

 

then theres basically no point in having stainless tubing...
