Stainless Steel Mig Welding Gas

Gases such as high helium and argon carbon mixture are ideal.

Stainless steel mig welding gas. You could also fancy a high argon gas 98 for your mig process. The table indicates the appropriate choice of shielding gas for mig mag welding taking account of different types of stainless steel and arc types. The shielding gas recommended for short circuiting welding of stainless steel contains 90 helium 7 5 argon and 2 5 carbon dioxide. Mig welding gas for stainless steel welding welding of stainless steel is typically done with c2 or 2 carbon dioxide and 98 argon.

For stainless steels there are also gases available containing small amounts of hydrogen h2. In some cases there is tri mix shielding gas containing 90 helium 7 5 argon and 2 5 carbon dioxide. If your process involves welding stainless steel you need a gas with significant energy conductivity. Therefore the recommended shielding gas to use for short circuit stainless steel mig welding is a tri mix shielding gas such as 90 he 7 5 ar 2 5 co2.

In some cases there is tri mix shielding gas containing 90 helium 7 5 argon and 2 5 carbon dioxide. Mig settings for stainless steel welding most of the mig welding machines often come with a table that is affixed to the machine that explains the amount of power supply type of wires shielding gases to be used electrode size and the wire feed rates etc. Mig welding gas welding of stainless steel is typically done with mixture of argon and carbon dioxide gasses that can be as low as 2 carbon dioxide to as high as 25 carbon dioxide. The high thermal conductivity of helium helps provide a flatter weld bead and good fusion into the base plate.

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. Besides this process is quite simple and easy to do than tig welding.
