Best Gas For Mig Welding Sheet Metal

For these types of materials a tri gas mixture is recommended which consists of 90 helium 8 argon and 2 co2.

Best gas for mig welding sheet metal. The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten. C2 or 2 carbon dioxide and 98 argon. C25 or 25 carbon dioxide and 95 argon. Furthermore if you plan to weld stainless steel er308 er308l and er308lsi welding wire are best used.

Mig welding sheet metal. Check out our project page for diy welding projects. 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. Most common gasses used to mig weld.

Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten. Tips for welding sheet metal with mig or tig. Always use the smallest wire diameter possible since smaller wires take less heat to melt and heat the metal less. 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.

But in the case of 316l stainless you will need to incorporate a 316l wire. Tig welding sheet metal.
