Description
A feasibility study was undertaken to investigate friction stir welding of hybrid lap joints between polyphenylene sulphide and AA 6111 alloy (Al, 0.76%Mg, 0.63%Si, 0.75%Cu) sheets (thickness 2 and 1.5 mm, respectively) and the influence of process parameters on joint properties. Welding experiments were conducted on a Hermie C50 milling machine using a tool made from heat treated H13 tool steel at a rotational speed of 1200 rpm and translational speeds of 10-30 mm/min. Microstructure was observed by optical microscopy, SEM and energy dispersive spectroscopy. Tensile-shear tests were performed on an Instron 4505 machine. Issues discussed include the joining mechanism and the relationships between heat input, translational speed and joint performance.
