Welding Stainless Steel Sheet Metal

With these materials use a tri mix gas 90 helium 8 argon and 2 co 2.

Welding stainless steel sheet metal.

Stainless sheet metal fabrication projects can be tricky. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire. For mig welding stainless steel a shielding gas mixture that s 90 percent helium 7 5 percent argon and 2 5 percent carbon dioxide is generally ideal. For thicker base pieces step up to 035 inch to 045 inch welding wire.

Some things that need to be considered include. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. Stainless steels which require special welding procedures are discussed in later sections. How to mig weld stainless steel.

To weld sheet metal with solid wires use electrode positive ep or reverse polarity. But in the case of 316l stainless you will need to incorporate a 316l wire. For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2. Make sure the fitup is tight with absolutely no gap.

In most cases mig welding stainless steel wire and sheet metal forms is pretty simple for marlin s manufacturing team. Although metal cored welding produces less spatter than other forms of wire welding the price per pound for the stainless steel filler metal is the highest. The best way i have found to tack weld stainless steel sheet metal is. Stainless steel is generally helpful in welding.

When deciding on this filler metal and process fabricators should weigh the upfront cost versus the productivity gains and the potential reduction in rework and cleanup. For most jobs welding stainless steel you ll want to use 030 inch diameter stainless steel welding wire. Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel.

However even this simple process has its complications.
