Title: Resistance spot welding method of aluminum
Inventor: IMAMURA YOSHIHAYA
IPC: B23K11/24
Filed: 1994-09-20
Abstract: PURPOSE: To improve the service life of a DC type electrode as long as that of an AC type electrode by employing a positive electrode made of copper of the prescribed purity which is connected to the positive electrode of a welding transformer to suppress the eccentric wear of the electrode attributable to the Peltier effect. CONSTITUTION: The phenomenon that a nugget is deviated in the direction of a positive electrode is observed when a chromium-copper electrode is used in the resistance spot welding of the DC inverter type. This is the phenomenon caused by the small cooling capacity of the positive electrode due to the Peltier effect, and is the main cause for the wear of the electrode due to the softening and alloying of the electrode tip to cause the eccentric wear of the positive electrode. Thus, the positive electrode is made of copper whose purity is >=99% which is excellent in the electric conductivity and the thermal conductivity and difficult to generate heat. As a result, the cooling capacity of the positive electrode is improved to suppress the heat generation of the positive electrode. The uneven wear of the positive electrode is prevented thereby.
