Abstract:
A process for resistance welding of metal parts, comprising:overlapping the metal parts (1, 2) to be welded together between a first (3) and a second (4) welding electrode during the welding process, clampingly fixing the metal parts (1, 2) to be welded together in place between the welding electrodes (3, 4), charging the welding electrodes (3, 4) and the metal parts (1, 2) to be welded together for a period time with an electrical current for welding, characterized in that at least one of the welding electrodes (4) is a circular cylinder, which is seated to be rotatable around its cylinder axis and whose surface area rests against one of the metal parts (2), at least during the period of time in which the welding electrodes (3, 4) and the metal parts to be welded (1, 2) are charged with the electrical current, rotating the circular cylinder (4) around its cylinder axis, so that a sliding friction is generated between the surface area of the circular cylinder (4) and the metal part (2) resting against it.
