Stud welding allows, through a simple process, the union of screw / stud and sheet metal without the need to pierce the surface, creating a heterogeneous union and eliminating production costs. It is definitely a simple and inexpensive process.

With a large stock of studs, machines and spare parts to attend to your demand “just in time”. And a technical team with more than 40 years of experience in the field of welding and joining techniques.


The insertion is carried out by introducing the insert to the surface through the grooved part, having previously perforated the metal sheet, and gradually pressing through a press, achieving a correct closure and a strong seal.

At Bearcat, through our exclusive Bearfix brand, we have a wide range of self-inserts: Studs, nuts, spacers … cold mechanical fasteners for insertion into thin metal sheet thicknesses ranging from 0.8 to 3, 2 mm. In galvanized steel, stainless steel and aluminum.
