TIG welding

Tungsten inert gas welding (TIG welding), also known as GTAW-gas tungsten arc welding, is a process used when very high welding quality is required for pressure vessels, piping, or food containers. An additional filler metal, often a wire rod, may be used either manually or in an automatic process through a separate wire feeder. Researchers at Air Liquide have studied this process to learn more about it and to propose the most suitable shielding gases like ARCAL™.
