1 INTRODUCTIONFriction stir welding ( FSW) is a new andpromising welding process that can produce low-cost and high-quality joints of many alloys[1 7]becauseit does not need consumable filler materialsand can eli minate some welding defects such ascrack and porosity . In the FSW process , thewelding temperature is lower than that in thefusion welding, and the metal is in the plasticstate ,so many fusion welding defects can be avoi-ded. At present , more and more researches havebeen focu… 相似文献
