TIG (Tungsten Inert Gas) Welding - ezinearticles.com

The idea of the use of non-consumable electrodes with inert gas shield for welding was first considered as early as 1920. However, the first patent for use of tungsten electrode with argon or helium shielding was reportedly issued in U.S.A. in 1930. Presently TIG welding is one of the most well established processes which can not only weld all metals of industrial use but also gives …
