Abstract

AA2219 aluminium alloy joints without filler metal addition were fabricated using gas tungsten arc welding (GTAW), electron beam welding (EBW) and friction stir welding (FSW) processes. The fabricated joints were post weld aged at 175 °C for 12 h. Microstructure analysis was carried out using optical and electron microscopes. It was found that the FSW joints were exhibiting superior tensile and fatigue properties compared to EBW and GTAW joints. Post-weld ageing treatment was found to be beneficial to enhance the tensile and fatigue properties of the welded joints, irrespective of welding processes. Post weld aged FSW joints showed the highest joint efficiency of 80 % and hence this process can be preferred over other welding processes to fabricate components and structures using AA2219 aluminium alloys.
