Description
In relation to the development of "AIRWARE" technology based on Al-Cu-Li alloys for aircraft structural parts, a report is presented into the friction stir welding (FSW) of "AIRWARE" 2050 alloys, mechanical characterisation of welded joints, and industrial demonstrations of large scale parts. FSW was performed using an MTS PDS machine with a conical threaded tool at a rotational speed of 250 rpm, travel speed of 200 mm/min and a vertical load of 52 kN. Ultimate tensile strength was studied as a function of welding temper and PWHT, and microhardness profiles were measured to quantify hardness reduction in the TMAZ (thermomechanically affected zone). Fatigue, fracture toughness and exfoliation corrosion tests were undertaken also. The demonstrators comprised a friction stir welded panel made from Alloy 2050, a friction stir welded rib, and a wing skin panel with a transverse weld.
