Default Stainless welding question

My wife's boss called and said that he is looking at a gas grill at HD with a broke hinge. He said the top is stainless and the weld is broken. He's thinking that if he can get it cheap, he will have it fixed. He asked me about welding it. I told him that i've never welded SS but I might be able to fix it.

My question: Could I weld it with my ER70-6 and 75/25% gas. It' on the inside so appearance isn't a problem. I just want it to hold. I don't mind getting a small roll of SS wire, but don't want a tank of argon that I won't use up. This isn't like welding on an airplane frame, so is it feasible?

Nope will not last even if you could make it stick, chrome carbide. You need argon and some SS wire, I would weld it with 316.

Options drill it and bolt or SS pop rivet.

Sure it's stainless & not chromed steel?

If it's stainless and you choose to weld it with the ER70S-6 and CO2 mix, it will work. You will lose the anti corrosion resistance by using steel wire & not stainless wire. But it will work.

Properly done, use either 308L or 316L wire & Tri-Mix gas. Tri-Mix is mostly Helium with Co2 & Argon mixed in, at a much smaller ratio.

I have a bottle of Tri-Mix & welded mild steel to stainless sheet. Worked ok, but the stainless has to be extremely clean. It also doesn't soak the heat away as fast as mild steel does either. So you need to weld it hot & fast.

Either way it will work, you just lose the corrosion resistance with ER70 wire.

Like STW says, I would drill and put in two to four 1/16" stainless pop rivets.

Default POP Rivet SS grill repairs

Most of the H.D.stuff is built on a very cost-minimal basis,I'd doubt it has any good stainless in it.I'm with everyone else here,put a POP rivet to it,use a stainless rivet if you can,they are stronger and will stand the heat. Yes you can weld stainless with ER70-S6 but it won't have the corrosion resistance the parent metal has.You probably have a hard time even getting anything substantial enuf to weld to anyway.BTW the average consumer out there today has no idea what real stainless costs,H.D.markets those nice looking chrome grills,thin metal POS's that don't last very long at all.A real stainless grill would run you 2K or more if you want one thats real,and last you a lifetime;they want you coming back to buy another cheapo in a couple years.The burners are the cheapest areas,usually stamped metal..the better grills have a bronze or cast iron burner assembly(ies) Best of luck with that POP riveter in the New Year.

I agree, if you do weld it use 316. The metal is provably paper thin and hard to weld. I would either bolt/ rivet or not buy it.

I have a Stainless Steel grill from Home Depot, its about 10 years old, looks as good today as it did the day I bought it, The inside components were/are true shit, they have been replaced at least 3 times. The metal is paper thin and is of questionable quality, I would pop-rivet it, I know I have.
