How To Mig Weld Stainless Steel Sheet Metal

However when working on large sheets of metal you will need more bracing.

How to mig weld stainless steel sheet metal.

To weld sheet metal with solid wires use electrode positive ep or reverse polarity. 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. Next join the metals using mig welding. As a rule when mig welding sheet metal never use a body filler metal that is thicker than the base metal.

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

Place the stainless steel metal over the table and hold firmly using the clamp. This process is performed by using a non disposable tungsten electrode with a tig welder for striking up the arc. Just make sure you use the right gas mixture wire and tweak the voltage little higher than you would normally use for regular steel.
