How To Mig Weld Stainless Steel Sheet Metal

This is basically a common and unique process for joining stainless steel.

How to mig weld stainless steel sheet metal.

It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work. This process is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. Place the stainless steel metal over the table and hold firmly using the clamp. To weld sheet metal with solid wires use electrode positive ep or reverse polarity.

As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal. 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. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire. You can also place a wooden plank between the joints to ensure they re apart.

Next join the metals using mig welding. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2. However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire.
