How To Mig Weld Stainless Steel Sheet Metal

Place the stainless steel metal over the table and hold firmly using the clamp.

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. As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal. You can also place a wooden plank between the joints to ensure they re apart. 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. This process also uses shielding gas against contamination but you can weld thinner metals more efficiently with it. To weld sheet metal with solid wires use electrode positive ep or reverse polarity. Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel.

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. This process is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc.
