gas is commonly used
06 Gas Tungsten Arc Welding Electrodes are
made of Tungston
07 One method to prevent transverse distortion
in a tee joint is to Tack weld both sides

tungsten electrode to suffer hardening
09 The two alloying metals added to tungsten
electrodes are Thorium and Zirconium
10 CO 2 gas is never used for GTAW because it
Cools the weld too quickly
