MIG/MAG and TIG welding

Metal Active Gas (MAG) welding is highly flexible and adaptive, and is used when you wish to obtain high productivity and high quality results. This process is used for manual and semi-automatic welding or automated/robotized installations on low-alloy carbon steels or high-alloy stainless steels.

Metal Inert Gas (MIG) is used for materials sensitive to oxidation such as aluminum or copper-alloys.

Tungsten Inert Gas (TIG) welding – commonly used for joining stainless steels, aluminum and aluminum alloys – enables a very high quality of weld to be achieved in particularly demanding projects, such as pressure vessels, pipelines, food industry containers and aircraft. The process uses an electric arc between the metals to be joined and an infusible tungsten-based electrode, located in the welding torch.
