This method is based on an electric arc burning between a tungsten electrode and the weldment. The weldment melts in this process. TIG (Tungsten Inert Gas Welding) welding is different in that the electrode is not consumed as it is in the other types of welding.
Advantages of this welding:
To perform WIG/TIG welding the company uses Tetrix 351 AC/DC welders.
