MIG/MAG and TIG welding

Metal Inert Gas (MIG) welding is a semi-automated welding process which is used for joining stainless steels, aluminum and aluminum alloys. The process melts and fuses metals using intense heat generated by an electric arc between the metals to be joined and the consumable filler material.

Metal Active Gas (MAG) welding is a semi-automated welding process which is widely used in shipbuilding, railroad construction and the production of heavy plants and machinery. The process melts and fuses metals using intense heat generated by an electric arc between the metals to be joined and the consumable filler material.

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 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.
