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, high-alloy stainless steels or non-ferrous alloys such as aluminum or copper.

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