Welding Stainless

[sweav]

I've never welded stainless before but I am going to try and rebuild my bars and a battery box out of stainless. I went today and picked up a spool of wire for my mig and checked to make sure I had the right gas. Anybody have any tips on welding it, is it any big deal?:cheers:

Yes, I have a tip.

Do not burn through... :laughing:

Just kidding.. I was not actually aware you could weld stainless on MIG...

Stainless burns very nice. Keep a clean welding surface and you will be fine. I welded some 3/4" plate gurders for bridges a few years back. I loved welding that stuff.

welding stainless is alot like mild steel. Use what they call tri-mix(argon,helium,co2) i likes a little more amperage too.

Yah, I found that if I turn the heat up it welded alot nicer. The box came out decent, I still need to do some more sanding to get it a little smoother.

Yeah I have done alot of stainless welding both mig and tig, I found as well as you that more heat the better the flow but be aware of warpage. If you get a chance try tiggin stainless oh man its the only way to go

when ya grind yur welds make sure to use a brand new grinding disk, if U use a disk thats been use with steel ya will see rust later on.....

Helium will make it weld hotter with out turning up the machine.I use tri mix.I got 6000 feet to weld on a large tank with 3" coils I use 2 - 25 lbs spools aday,I'll be glad with I'm finished
