WebIn gas tungsten arc welding (GTAW), also called tungsten inert gas welding, the electric arc is created between a nonconsumable tungsten electrode and the parts to be joined. As in GMAW, inert gas shielding is used around the arc to protect the weld pool. Tungsten is a good electrode material because of its high melting point of 3410°C. WebGas welding is one of the oldest forms of heat-based welding and is utilized in many industries. There are also welds that employ the use of a shielding gas to help protect the weldment from contaminants, such as gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). Having a knowledge and understanding of what gas welding is can ...
