Abstract

The study was aimed to investigate the metallurgical properties of semi-solid metal aluminium alloy 5083 welding using gas metal arc welding, with the variation of 5, 10 mm, and one-sided lap joint. The weld is characterized by a complete melting, and macro structure had no twist and cracks caused by the residual stresses in the weld. The small amounts of porosity were observed throughout the weld area. From the twoway lap joint at 10 mm, the penetration depth is better, and the porosity is less than the 5 mm lap joint. The microstructure of the base metal is composed of spheroidal grain structure (α), mixed with eutectic phase (Mg + Si). The pore size is 5 to 20 microns. It has a uniform distribution of Mg2Al3, which is smaller than the structure of the heat affected area. From the inspection does not show the crease of the weld. It showed that 5083 semi-solid aluminum alloys can lap joint with the gas metal arc welding
