Abstract
The present invention provides a method for manufacturing a joined body that allows for the determination of the quality of a weld solely based on the resistance value measured during welding. [Solution] The method for manufacturing a joined body includes: sandwiching multiple metal workpieces between a first electrode and a second electrode, and welding the multiple metal workpieces by passing a welding current, set so that the resistance value between the electrodes is within a predetermined range, between the electrodes; measuring the resistance value between the electrodes from the current value of the welding current and the voltage value between the electrodes during the welding period; determining whether the measured resistance value is within a preset allowable range, and performing quality confirmation to determine if the welding quality is poor when the resistance value is outside the allowable range.
