DEVICE FOR INSPECTING RESISTANCE WELDING

摘要

PROBLEM TO BE SOLVED: To provide a device for inspecting resistance welding capable of easily confirming the quality of welding in resistance welding. SOLUTION: Whether or not excellent resistance welding is executed is judged even in resistance welding wherein welding is finished in a short time and a cause in defective welding is surely judged by displaying at least for a specified time a welding current and voltage in the resistance welding, a pressurizing force exerted on an object to be welded in welding, resistance in the object 4 to be welded and change of respective parameters due to a quantity of deformation of the object 4 to be welded in the welding.
