PROBLEM TO BE SOLVED: To easily remove obstacles against resistance welding which are formed on a surface of an electrode for resistance welding. SOLUTION: An electrode 4 is abutted on one side of a welding part where conductors 1 and 2 contact with each other, and an electrode 3 is arranged with a space from the welding part of the other side conductor 1. In such a state, voltage is applied between the electrodes 3 and 4. As a result, An arc A<SB>rc</SB>is generated between the conductor 1 and the electrode 3, and the resistance welding obstacles such as an oxide film 7 and dust, which are formed on the surfaces of the conductor 1 and on the electrode side of the electrode 3, are scattered and removed by the arc A<SB>rc</SB>. After the cleaning, the electrode 3 is abutted on the welding part of the conductor 1, and the welding part of the conductors 1 and 2 is sandwiched between the electrodes 3 and 4. In this state, the resistance welding is carried out by applying the voltage between the electrodes 3 and 4. The cleaning by the arc is performed very easily and rapidly. The excellent resistance welding is realized by removing the resistance welding obstacles. COPYRIGHT: (C)2005,JPO&NCIPI
