Our welding processes

MIG welding - Metal Inert Gas - our welders use helium, argon or a synthesis of both. For MAG welding - Metal Active Gas - we use a mixture of argon and carbon dioxide. Our welders can also perform TIG welding. This type of welding, obtained using an electric arc, is perfectly mastered by our welding team. To these welds are added spot welding, steel welding, aluminum welding, and also stainless steel welding.
