| 摘要 | The relatively short electrode life in welding aluminum sheets has been a bottleneck for large-scale production of aluminum vehicles. The rapid deterioration of electrodes during resistance welding aluminum is the collective consequence of high pressure, high temperature, and a rapid metallurgical (alloying) process. This study systematically investigated the effects of sheet surface conditions on electrode life. Using 2-mm 5A02 aluminum sheets, a schedule conducive to electrode life was used for testing the effects of sheet surface conditions. A three-phase, direct-current pedestal-type resistance spot welding machine was used, and the electrodes lasted for about 200 welds for sheets with untreated or original surfaces, up to 1700 welds when they were electric-arc cleaned, and more than 2000 welds if the sheets were degreased or chemically cleaned. This investigation also shows that the appearance of an electrode after a small number of welds provides useful information on the electrode life using the same welding schedule. |
