Quality assurance method used during resistance spot welding comprises welding the joining partners between welding electrodes, acquiring an acceleration signal during welding and controlling parameters of the welding process

摘要

Quality assurance method comprises welding the joining partners between welding electrodes, acquiring an acceleration signal during welding which represents the acceleration of the electrodes and controlling parameters of the welding process when a prescribed theoretical value is exceeded and/or the amplitude and/or the frequency of the signal is changed.
