Abstract

The Skew-stir™ process, a variant of the friction stir welding (FSW) technique developed at TWI, was used for the production of lap joints in aluminium alloy AA5083-0. This process differs from the conventional method in that the axis of the tool is given a slight inclination, or skew, to that of the machine spindle. It is particularly advantageous in cases where a wide weld region is required, such as lap joints where the interface is perpendicular to the machine axis. The microstrucrures and tensile properties of welds made using both a conventional pin-type probe and the rotary Skew-stir technique with an A-Skew™ probe were studied.
