Gas tugsten arc welding (GTAW) or Tungsten inert gas (TIG) GTAW The TIG (tungsten inert gas) welding process, identified by the AWS as Gas Tungsten Arc Welding-GTAW, is an electric arc welding process, which is established between a tungsten electrode and the workpiece, under the protection of an inert gas that avoids the contact of the air with the melting bath and with the electrode, which are at high temperature. | Kaynakcilar ve Borucular EMEK Platformu
