METHOD AND DEVICE FOR OBTAINING INFORMATION FOR EVALUATING A RESISTANCE WELDING QUALITY AND/OR FOR CONTROLLING OR ADJUSTING A RESISTANCE WELDING METHOD

摘要

The invention relates to a method and device for obtaining information for evaluating a resistance welding quality and/or for controlling or adjusting a resistance welding method. The inventive method is characterised in that at least one first voltage (UEL1) is measured between a first welding electrode (12) and the first (16) of welded parts during welding. Said method makes it possible to obtain information for evaluating the quality of a resistance welding or for controlling or adjusting a resistance welding process in a simple and low-cost manner.
