Definitions
- the present invention is related to a spot welding gun used for joining two metal sheets by melting the metal at a point by means of the heat produced by the high electrical current passed through the metal structure.
- the object of the present invention is to develop a modular spot welding gun, that provides a multi-purpose production flexibility which is not dependent on the geometry and sheet thickness of the spot welding zone.
- the electrode holder (6) being one of the parts that provide the modularity of the welding gun (1) is made of a highly conductive material, preferably of copper.
- the electrode holder (6) made of a material cast as a solid or hollow tube provides the conduction of the electrical current and of the cooling fluid. It is made of a material having a hardness ratio (HBR) greater than 72, with respect to the material strength feature.
- HBR hardness ratio
- the capacity adjustments such as the length, clamp opening, electrode axis gaps and momentum can suitably be adapted, without changing such parts as the lower and upper clamp (2,3), cylinder (5) and joint
- the welding gun (1) provides considerably advantages with respect to production investment costs and time, due to its modular production structure.
- the possibility of replacing the worn parts and material increases the service life of the modular welding gun (1).
- reducing the types and standards to be used facilitates the production estimates, lowers the stock (storage costs) and eliminates the difficulty of management.
