Shielding gas for TIG welding
Shielding gas is one of the key parameters in the TIG welding process. We know that the shielding gas is mainly Ar and CO2 used in TIG welding, in many applications, O2, H₂, He or N₂ can be added to improve the welding quality. In addition to argon, helium or a mixture of argon and helium can be used […]
