Abstract
A high strength aerospace aluminum alloy, 24~25 mm thick plate, has been friction stir welded using four different process variants. The process variants used are: stationary shoulder single pass (SSSP), conventional shoulder single pass (CSSP), stationary shoulder dual pass (SSDP), and conventional shoulder dual pass (CSDP). The goal of the reported work was to optimize properties while maintaining nugget temperature below the incipient melting temperature. Defect free welds were produced by all process variants. Properties and characteristics including residual stress, hardness distributions and process control and response parameter relationships are reported.
