weld

Heliarc welding, also known as gas tungsten arc welding (GTAW), is a welding process that uses an electric arc between a tungsten electrode and the workpiece to melt the metal at the joint. The process is shielded from the atmosphere by a blanket of inert gas, typically argon or helium. Heliarc welding is often used for welding thin materials, such as stainless steel and aluminum, and for welding in critical applications, such as in the aerospace and medical industries.

Heliarc welding offers several advantages over other welding processes. First, it produces high-quality welds with excellent penetration and minimal distortion. Second, it is a relatively clean process, producing little smoke or spatter. Third, it is a versatile process that can be used to weld a wide variety of materials. Finally, it is a relatively safe process, as it does not produce harmful fumes or radiation.
