MIG | MAG | TIG welding: At Covertek we offer a manual MIG (Metal Inert Gas), MAG (Metal Active Gas) and TIG (Tungsten Inert Gas) welding service. These are inert, oxidizing or active shielding gas welding processes. They produce high quality results, both on small and thick parts. Laser welding: Through the fusion of metals or thermoplastics, joined by means of a focused laser beam, at Covertek we are able to apply this welding process in various sectors of activity.
