Heliarc welding, also called fuel tungsten arc welding (GTAW), is a welding course of that makes use of an electrical arc between a tungsten electrode and the workpiece to soften the metallic on the joint. The method is shielded from the environment by a blanket of inert fuel, usually argon or helium. Heliarc welding is commonly used for welding skinny supplies, corresponding to chrome steel and aluminum, and for welding in important functions, corresponding to within the aerospace and medical industries.
Heliarc welding affords a number of benefits over different welding processes. First, it produces high-quality welds with glorious penetration and minimal distortion. Second, it’s a comparatively clear course of, producing little smoke or spatter. Third, it’s a versatile course of that can be utilized to weld all kinds of supplies. Lastly, it’s a comparatively secure course of, because it doesn’t produce dangerous fumes or radiation.
