Resistance element welding

Flexible joining of lightweight materials


Flexible and process-reliable

WELTAC® resistance element welding enables the joining of lightweight materials with steel of all qualities.

For the joining of materials in car lightweight design, especially aluminium and steel, Böllhoff has added another technology to its product portfolio: the resistance element welding.

Resistance element welding is a further development of resistance spot welding.

At WELTAC®, a rivet-like resistance element ensures, that materials which are not thermally compatible, or only to a limited extent, are joined. The resistance spot welding systems, existing at the customers’ premises, can still be used for modern body construction architectures.
