Long story short;

While the site was down had an 1/8" thick stainless steel motor mount on the tower of my automatic carwash break. My buddy who loans me his TIG works 3rd. He had just gone to bed when I got ahold of his wife. Couldn't wait for him. Bought a 2 lb. stainless spool at the local Farm & Fleet type store. Got to the shop and duh my welder won't take those little spools. Briefly(very) thought I'd gas weld it. At that point I'm like screw it, welded it back together with regular MIG wire. Had to be flush so welded both sides, but ground them smooth.

So, what's the expected durability of my repair? My guess is that if anything it'll crack right beside the current welds?

What metal is the parent metal and filler?

Actually, I'm stil not sure exactly what you did and what it looks like

'welders'
A 'welder', see also "welder", is the thing you plug into the wall.

A weldor is the mf'er that runs it. Look it up...

Hack,

The parent material is stainless. Don't know what alloy. I'd imagine recycled sinks.

Filler is general purpose MIG wire.

It welded nice and seemed to flow together.

Now that I've done this it's contaminated with the MIG wire so if it breaks again there's no doing it right? <- That's a question.

It's buried in the tower so if it's fixed forever I'd like to forget about it. If it's likely to rebreak because of how I welded it need to get another one ordered

general purpose? like 308?

sink? likely 316?

That wouldn't be a correct way and I have no idea how it? is loaded or how heavy it? is.

I can't imagine you've done something that could not be fixed. Its not like you burnt a piece of ti or cooked a piece of super duplex.

Does anyone bleed if it fails?

about a month ago, i was talking with an old muffler shop guy, who says he uses a mig with regular mild wire to weld ALL of his stainless exhausts....he's been doing it for over 30 years with no problem...that's my only input...

You can do that, the welds will rust and I'd punch an exhaust guy that charged me for a stainless exhaust and welded it with mild steel

It also will not be as strong but exhaust systems are not typically exposed to loads of structural magnitude and the welds typically seal more than hold together slip fitted pipes.
