Method for calibrating resistance welding machine comprising welding head mounted on robot arm with electrodes mounted on swiveling arms comprises measuring power between electrodes using sensor

摘要

Method for calibrating a resistance welding machine comprising a welding head (2) mounted on a robot arm (3) with electrodes (8) mounted on swiveling arms (6, 7) comprises measuring the power between the electrodes using a sensor (10) which is moved into the gap between them. An independent claim is included for a welding machine incorporating the calibration system.
