Semi-Solid State Joining of SSM Aluminum Alloys Using Brazing ZA27
Semi-solid state joining of SSM A356 aluminum alloy under normal atmosphere using ZA27 as a filler was investigated. Localized semi-solid pool of ZA27 filler was created by an induction heating coil for butt joint of SSM A356. Then a stirrer was applied into the weld seam to stir the filler. The acc...
