What Kind Of Gas For Welding Stainless Steel. Welding Gas for Stainless Steel While choosing the Shielding gas for MIG welding stainless steel welders usually prefer a mixture consisting of Argon 98 and CO2 2 while some prefer to use the gas mixture of Helium -90 Argon 7 and CO2 2. TIG welding or tungsten inert gas welding is another form of welding that uses an inert gas.
This is the gas covered wire you use for welding stainless steel to mild steel. Type 308L for flux core welding 300 series stainless steel up to type 308. Nitrogen can be used for duplex steels to avoid nitrogen loss in the weld metal.
Some gases are better suited than others for the most commonly used base materials whether its aluminum mild steel carbon steel low-alloy steel or stainless steel.
However TIG welding uses only inert gas. Type 308L for flux core welding 300 series stainless steel up to type 308. Right around 5 corrosion picked up. Ad Find China Manufacturers Of Welding Wire.
