Can you tack steel to stainless steel ?

Building a coffin gravity racer and I have a piece of stainless tubing that I'd like to run a steel bolt through and then tack it so it stays put.

What happens when you try to weld stainless to regular steel ?     I'm using a Hobart 220 mig with shielding gas.

Yes if you use stainless filler rod you should be fine but tig would be better

I guess i should add, that the welding wire I have in the machine is for normal steel. 

Normally, I'd just try it and see what happens, but the parts are painted and if it doesn't/will not work, I'd rather leave things alone so I don'e have to patch up the paint work.

A friend patched a hole in my muffler with a piece of thin stainless and I think he used regular wire.

Anyone think it would it be possible to patch an exhaust with some stainless sheet, using an Arc/stick welder and small  stainless rods?
Or would it more than likely to blow holes even with 1.6mm or 2 mm electrodes?

Yep, you can MIG stainless to mild, or mild to stainless using plain wire, no problemo. Same/same for stainless wire. Cheers, Terry.

Arc welding is really better suited for welding thicker material mate, but you can probably weld anything if you're patient enough. Cheers, Terry.

I will just throw it in here, there is a gassless SS wire for MIG now:



I am sure welding under gas is better, but it is good to have an option.

I would use inert gas, and avoid being near a fan.  I bet it can be done, though.
