Stainless Steel Mig Welding Gas

In some cases there is tri mix shielding gas containing 90 helium 7 5 argon and 2 5 carbon dioxide.

Stainless steel mig welding gas. Welding gas for stainless steel. Welding of stainless steel is typically done with c2 or 2 carbon dioxide and 98 argon. Parent metal type of material austenitic stainless steel duplex stainless steel super duplex stainless steel ferritic stainless steel. In some cases there is tri mix shielding gas containing 90 helium 7 5 argon and 2 5 carbon dioxide.

It s also good for welding stainless steel based on the following reasons. Alternative gases that you can use are 98 argon and 2 co2 or 98 argon and 2 oxygen mix. The process of mig welding stainless steel basically requires you to continuously feed a solid electrode wire inside the weld pool along with some shielding gas in order to protect the weld from all sorts of contamination. How to mig weld stainless steel.

Therefore you do not want to use a completely inert shielding gas such as 100 helium or 100 argon for stainless steel mig welding. It uses a shielding gas. Mig welding gas for stainless steel welding. Again many welding supply stores carry their own mixture that can improve the weld quality and ease of.

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. The table indicates the appropriate choice of shielding gas for mig mag welding taking account of different types of stainless steel and arc types. 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. Besides this process is quite simple and easy to do than tig welding.

Do not confuse this recommendation with the recommended shielding gases for the gas tungsten arc welding or tig process which is 100 argon or 100 helium or a mix. The arc characterisitcs would be poor. Since stainless steel has low heat conductivity using a welding application that features a shielding gas is. The shielding gas recommended for short circuiting welding of stainless steel contains 90 helium 7 5 argon and 2 5 carbon dioxide.
