Welding Stainless Steel Mig Gas. Gases such as high helium and argoncarbon mixture are ideal. For stainless steel metal the recommended shielding gas mixture is a combination of helium 90 argon 75 and carbon dioxide 25.
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. Alternative gases that you can use are 98 Argon and 2 Co2 or 98 argon and 2 oxygen mix. Besides this process is quite simple and easy to do than TIG welding.
You can use pure argon gas or argon plus carbon dioxide gases.
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. You can use pure argon gas or argon plus carbon dioxide gases. How To MIG Weld Stainless Steel. Regardless of what anyone else says you shouldnt use a mix of more than 25-3 Co2 for Mig welding Stainless Steel.
