Principle An arc welding process that uses a constricted arc between a non consumable electrode and the weld pool (transferred arc) or between the electrode and the constricting nozzle (non-transfered arc) Gas Tungsten Arc Welding 2. Operating Modes Manual Yes Semi Automatic No Mechanized Yes Automatic Yes 3. Advantages & Limitations i. Main advantage is the higher energy constriction ii. Torch to work distance is less critical iii. High temperature and high heat concentration allow for the keyhole effect iv. Higher Travel speeds Gas Tungsten Arc Welding 6. Equipment .
