The joints welded by friction stir welding are homogeneous inmicrostructure and predominant in mechanical capacity. Because ofthe virtue ,such asthe security, nosplash, noradiation and nopollution during friction stir welding, and soon, sothis technique iswidely utilized inindustry. Inaviation industry, aircrafts made byaluminium alloy are usually welded byfriction stir welding. Abroad market isexplored ofFSW inother countries, and also making areformation inthe manufacture ofwatercraft. With the further acknowledgement toFSW, the joint ofaluminium alloy, magnesium alloy, zinc alloy and titanium alloy will bewelded byFSW. Especially, the carrier rocket ,high velocity aluminium alloy train, high velocity alminium alloy speed boat and aluminium alloy vehicle will be possibly welded bythe FSW.
