영문 초록

Among light alloys. compound Il1ctal of aluminllll1 has bccn applicd widcly on accollnt of light wcighl and specific strength, but lhe aluminum 8110y can bring about deforll1ation by welding heat and defects sllch as porosity and crack casily in casc of ll1anufaclurinμ structw c by 1l1(、Iting weldinμ. 1n addition, intens ity of joint can be deteriorated easil y, so new technology is demanded. 10 1981 , TWI dcvclopcd Friction Stir Wclding, non-rnclLing progrcss and lhis progress has bcen expanded into various industries widely. FSW lechnology, originated from rriction welding, is in the limclight of a wclding 1l1clhod which causcs littlc dcformation, is non-consumablc, and supplics high Quality joint without welding defection, fume. noise and harmful ligh t. 1n this study, principle and charactcristics of FSW with AI 707 allov a ll10n various aluminum alJoys aft! invcstigatcù änd analyzed by using tech nical charactcristics ()f FS ， as a new method which can solve the problel11 ()fl11elting welding of aluminum a!loy The experimenL is carriec1 ouL with AI 7075 made by ALCOA EUROPE with thickness of 8m1l1, tα)1 which mm has pins 7.5mm in length with stirring speed for 400, 600. Hα) rpm with welding speed f()r 2, 1mm/sec. fì specinwn was produced after friction welding experiments, changing each condition. After welding experiments, macroscopic Lest, lensile strengrh, and hardness are investigated and analyzed.
