Best Gas For Mig Welding Sheet Metal

Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less.

Best gas for mig welding sheet metal.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Because it will have you a lot more control over. 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. For mig welding sheet metal it is often recommended to use an electrode wire of the smallest diameter to prevent burn through and warping.

Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used. For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2. Tips for welding sheet metal with mig or tig.

C2 or 2 carbon dioxide and 98 argon. But in the case of 316l stainless you will need to incorporate a 316l wire. The main reason to use a smaller diameter wire is that it takes less heat for melting and hence the metal around the weld is not heated to a very great extent. C25 or 25 carbon dioxide and 95 argon.

The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten. Tig welding sheet metal.
