Welding device control method and welding device
First Claim
1. A process for welding comprisingproviding a welder having tongs for applying an electrical current, an actuator of applying an electrode force and a sensor for measuring the electrode force,providing material to be welded in between the tongs,conducting a working phase, the working phase comprising a succession of spatially offset welding spots to join the material to be welding,conducting a testing phase comprising executing a series of spatially offset welding spots, the welding current increasing by first increments after each welding spot until the spatter limit of the material to be welded is reached,decreasing the welding current by a second increment, andconducting a second working phase comprising a succession of welding spots.

Abstract
The invention concerns a welding device control method and a novel welding device for the electrical spot or resistance welding of material to be welded. The welding device comprises at least two weld electrodes which, for the welding process, are pressed by an actuating device at a predetermined electrode force against the material to be welded. The welding device further comprises a control system which controls the welding current via a controller.
