Abstract

Gas metal arc welding (GMAW) and double sided welding techniques were used to join 6 mm thick AA6061-T6 aluminium alloys plates. The ER5356 sample exhibited greater grain size and thicker grain boundary than the ER4043 sample due to higher range of heat distribution during the welding process. The fusion boundary for the ER4043 sample can be seen clearly, but for the ER5356 sample, a part of the base metal has been found to be fused and dissolved wit d metal. The weld metal of the first welding pass exhibited finer microstructure than the second welding s for both samples. As compared to the base metal, the ultimate tensile strength and strain of the ER4043 sam e decreased by 48% and 94% respectively, while for the ER5356 sample, the degradation of strength and strain is slightly lower, 41% and 62% respectively. The hardness of the HAZ regions is tremendously decreased and immeasurable at close distances to the weld metal.
