Stainless Steel Sheet Welding

Welding is a way to combine pieces of stainless steel together for repair work and even craft projects.

Stainless steel sheet welding.

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. For thicker base pieces step up to 035 inch to 045 inch welding wire. Again stainless steel and the filler metals used to weld it generally are more expensive than carbon steel. To weld sheet metal with solid wires use electrode positive ep or reverse polarity.

How to mig weld stainless steel. Stainless steel is generally helpful in welding. Alternative gases that you can use are 98 argon and 2 co2 or 98 argon and 2 oxygen mix. In resistance welding lower current can be used because resistivity is higher.

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. The best way i have found to tack weld stainless steel sheet metal is. To begin a weld set the steel in place over a welding table using clamps and jigs. However even this simple process has its complications.

Then join the steel together through mig or tig welding. In addition to welder skill and equipment availability the application priorities cost productivity and bead appearance for example influence which stainless steel welding process fabricators ultimately choose. For most jobs welding stainless steel you ll want to use 030 inch diameter stainless steel welding wire. Even though most of the welding machine manufacturers have included a table of materials and voltage settings in the machine it is highly important for you to pick the right kind of gas and electrode wire to be used for mig welding stainless steel.

In most cases mig welding stainless steel wire and sheet metal forms is pretty simple for marlin s manufacturing team. Stainless steels which require special welding procedures are discussed in later sections. Mode of metal transfer. When welding 304 stainless steel er308 er308l and er308lsi wires are compatible but for welding 316l stainless you need a 316l wire.

The gas gives the most desirable bead contour while keeping the co2 level low enough so that it does not influence the corrosion resistance of the metal. Make sure the fitup is tight with absolutely no gap prop your tig cup right on the joint with the sharp tungsten electrode tip less than 1 16 from the joint. Some things that need to be considered include.
