Description

Aluminium alloy 7050-T751 was friction stir welded using a range of process parameters, and finite element analysis was used to calculate the time-temperature distributions so that the resultant weld properties could be related to the welding parameters. A typical friction stir welding tool with a threaded, cylindrical pin and a dished shoulder was used to weld plate of 6.4 mm thickness at welding speeds of 0.86-5.1 mm/s, using three different ratios of welding speed to tool rotation rate. The specific energy inputs were determined for the welds, which were characterised by measurements of hardness distribution, with and without PWHT.
