How To Mig Weld Stainless Steel Sheet Metal

Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel.

How to mig weld stainless steel sheet metal.

You can also place a wooden plank between the joints to ensure they re apart. Next join the metals using mig welding. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire.

Place the stainless steel metal over the table and hold firmly using the clamp. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2. As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal. However when working on large sheets of metal you will need more bracing.

If you already have some experience in the world of welding you should be completely capable of mig weld stainless steel even with a regular hobby welding machine. This process is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire.
