Applications

Nut welding

With the projection welding process, very different functional elements such as nuts, bolts, spacer sleeves, etc. can be welded to the flat areas of the components. The required welding projections must be provided for in the design of the functional element and determine the dynamics of the welding process by their shape, number and type.

The required welding currents depend, among other things, on the total cross-section of the welding projection and can range from 10 kA to over 100 kA. Depending on the size of the system, the impedance of the secondary circuit and the type of welding transformer used, primary currents of up to 3,000 A are required for individual welding points.

In addition to numerous industrial applications, nut welding process is actively used in the automotive industry. There, the nuts and bolts are welded to the coated body parts made of different types of steel. Thanks to our special software solutions, the welding process can be easily automated and controlled in mass production.
