The bolt-welding device with improved connection of the stud welding head, as well as adapter for the fastening of the stud welding head on the robot

摘要

The invention relates to a bolt-welding device for the automated welding of the welding bolt on the workpiece surface by means of electric arc, comprising a robot (200) and at least one robot arm (210) to the fixed bolt welding head (100). It is provided that the bolt welding head (100) a connecting flange (120) for the releasable attachment to the robot arm (210), said connecting flange (120) by means of integrated electrodes - and pneumatic connections (171, 172), so that the electrical and pneumatic connection and supply of the stud welding head (100) only by way of the connecting flange (120) can take place.
