Welding of aluminum alloys is an important process used in several industries, including automobile, shipbuilding and the aerospace. Welding aluminum alloys using traditional welding methods is difficult be-cause of a various reasons, particularly melting of aluminum; however, friction stir welding (FSW) is a non-fusion solid-state welding technique, which can prevent bulk melting of aluminum during the process, hence acceptable joining approach for aluminum alloys. Friction stir spot welding (FSSW), a form of FSW, is a potential method for creating spot connections between Aluminum alloys. The weld quality and mechanical properties are affected by tool geometry and the process parameters utilized during FSSW. In this work, the friction stir spot welding techniques of aluminum 2024-T3 are successfully carried out utilizing a welding tool made of D3 steel. This experimental work utilizes process parameter such as spindle speed of 1500 rpm, 1750 rpm & 2000 rpm with dwell time of 2s, 4s and 6s. We investigated the effects of dwell period and spindle speed on shear stress while keeping the plunge rate and depth constant. The force exerted on the FSSW tool during the welding process is also investigated for the specified dwell time and spindle speeds. The highest tensile shear force was reported for a weld formed at 2000 rpm with a dwell time of 6 seconds. |
