MAG and TIG welding

Metal Active Gas (MAG) welding is highly flexible and adaptive, used when you wish to obtain high productivity and high quality results. This process is used for manual (semi-automatic) welding or automated/robotized installations on low-alloy carbon steels, high-alloy stainless steels or non-ferrous alloys such as aluminum or copper. Metal Inert Gas (MIG) welding mixes are mainly used for sensitive stainless steels and aluminum or copper-alloy welding.

Tungsten inert gas welding (TIG) or GTAW-gas tungsten arc welding (GTAW) is a process used when a 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 ARCALTM.
