How To Mig Weld Stainless Steel Sheet 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.

How to mig weld stainless steel sheet metal.

With these materials use a tri mix gas 90 helium 8 argon and 2 co 2. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire. However when working on large sheets of metal you will need more bracing. This is basically a common and unique process for joining stainless steel.

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. It is recommended that a welder should use 023 or 024 inch wire for light gauge sheet metal work. However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire.

Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel. This process is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. Next join the metals using mig welding.
