Description
A report is presented into recent advances made in friction stir welding (FSW) of 7075 aluminium alloy and 12%Cr alloy steel plates (thickness 12 mm) using refractory metal tools in conjunction with a variety of surface modifications, including studies of the interactions between shoulder, probe and workpiece, and tool material evaluation in terms of weld quality and wear performance. Weld surface quality and macro-section observations together with tool visual inspection results are reported for FSW of 7075-T6 using both untreated and coated refractory metal tools. Force feedback data and weld mechanical properties are discussed also. A treated refractory metal tool is presented for FSW of 12%Cr steel and weld surface quality, microstructure and tensile test results are reviewed.
