摘要:
A resistor welding machine control method for calculating a temperature distribution at a portion to be welded by using changes in welding current and voltage across two welding electrodes during welding and information on sheet combination sequence at a spot-welding position, and for controlling at least the welding current or pressure applied to the electrodes by using the calculated temperature distribution. The present invention can thus provide a resistor welding machine control method capable of controlling welding quality accurately. Spot-welding position information, wear comparison information and the like are available as other information.
