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.

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. However if you are dealing with materials that are 18 gauge or thicker one should be able to use 030 inch welding wire. Next join the metals using mig welding. To weld sheet metal with solid wires use electrode positive ep or reverse polarity.

This is basically a common and unique process for joining stainless steel. 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. 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 also uses shielding gas against contamination but you can weld thinner metals more efficiently with it. You can also place a wooden plank between the joints to ensure they re apart. With these materials use a tri mix gas 90 helium 8 argon and 2 co 2.
