Argon Gas For Mig Welding Stainless Steel. You really need a pocket welding guide Laresmojica. Basic shielding gas choices for Stainless are.
Formier gas N 2 5 - 12 H 2 is an excellent alternative for conventional austenitic steels. Pure argon is by far the most common gas for root protection of stainless steels. Although the gas flow rate will depend on a lot of factors as I have explained before the preferred range for working on stainless steel is around 20 to 25 CFH.
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.
You could also fancy a high argon gas 98 for your MIG process. It is best to use a combination of the MIG welding gases in order to get the best results for your specific project. C10 or 10 Carbon Dioxide and 95 Argon. However as the thickness of the material increases fusion and porosity problems can arise due to the arc being more.
