PROBLEM TO BE SOLVED: To provide a method of resistance welding wherein electrode pressurizing force smaller than weight of a supply mechanism for electrode pressurizing force can be obtained and thermo-compression bonding or spot welding of workpieces can be done by reducing or increasing the electrode pressurizing force in welding. SOLUTION: The method comprises the steps of moving an electrode to the workpieces, detecting that the electrode abuts on the workpieces, pressurizing the workpieces, energizing the electrode, measuring a displacement quality of thickness of the workpieces in welding, reducing or increasing the electrode pressurizing force in welding when the displacement quality of the workpieces reaches the given value, stopping energizing the electrode after a specific time and making the workpieces held by the reduced or increased electrode pressurizing force after the welding expiration. The thermo-compression bonding or spot welding is done by the method. |
