Description
With regard to the development of aluminium military vehicles, a report is presented into production level single run friction stir welding (FSW) process parameters for thick plate samples (thickness 12.7-40.6 mm) of 5083, 5059 and 2139 aluminium alloys and welding procedures to meet ballistic shock testing requirements. FSW trials were conducted on a GTC (General Tool Company) AccuStir gantry style machine. Static tensile and bend tests were undertaken according to ASTM E8 and E290 guidelines, respectively. Weldments were evaluated by ballistic shock testing and phased array ultrasonic testing to find lack of penetration and wormhole types of defects. Issues discussed include FSW tool designs, welding trials to determine the limits of the process parameter window, cross-weld static tensile properties, tool life tests, lack of penetration and wormhole defects, and technology transfer to aid in military vehicle production.
