Semi-Solid State Joining of Aluminum Alloys under Nitrogen Shielding Gas

Abstract:

The purpose of this research is to investigate the semi-solid state joining of SSM 356 aluminum alloy which welded at its semi-solid state by using oxygen - acetylene as a heat source. Then a stirrer was used to stir the weld seam. Joining was performed under nitrogen shielding gas. The parameters of this study were rotation speed at 1,110 and 1,320 rpm, welding speed at 120 and 160 mm/min, semi-solid state temperatures 575-590 and 590-610 oC. The results indicated that the weld's microstructure consisted of irregular globular structure. In addition, porosities were found at top of weld metal. The highest tensile strength and elongation were obtained from rotation speed at 1,110 rpm, welding speed at 120 mm/min and joining temperature at 575-590 oC.
