Abstract: The measurement of the voltage over the welding point in order to supervise the welding quality takes place by means of voltage taps on the wire electrodes. As a result, the additional parasitic resistances during measurement by means of conventional voltage taps on the roller head or the roller head mounting are completely eliminated, which improves the measuring accuracy.

Abstract: Owing to the fact that sheet edges (3.1, 3.2) to be welded according to the invention are preheated before they are welded, a smaller temperature gradient arises in the material to be welded at the same welding speed during the welding. Consequently, the welding speed can be increased or material which gives poor welding quality at a high temperature gradient can be welded. The preheating is realised, for example, by excitation of the material to be welded at a high frequency.
