MIG and TIG welding

Metal Inert Gas (MIG) welding is a semi-automated welding process that 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 a filler wire.

Tungsten Inert Gas (TIG) welding is 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 and pipelines. The process uses an electric arc between the metals to be joined and an infusible tungsten-based electrode, located in the welding torch.
