  • Publication number: 20210379689
    Abstract: According to one embodiment, a control device controls a welding device performing resistance welding. When an inspection value satisfies a first condition, the control device modifies a setting value for the resistance welding and causes the welding device to perform the resistance welding. The inspection value is obtained by an inspection of a weld zone formed by the resistance welding. The control device does not cause the welding device to perform the resistance welding when the inspection value satisfies a second condition.
