Embodiment 1
[0032] The first aluminum alloy plate to be welded with H1 = 4mm and the second aluminum alloy plate to be welded with H2 = 4mm are assembled with a lap joint structure to form the lap joint surface A, and the length L1 of the lap joint surface is selected as 15mm. Then use the above-mentioned welding device and welding method to carry out friction stir welding: the total length of the stirring needle L4=5.4mm, the length of the first-stage stirring needle L3=3.65mm, the downward pressure=0.2mm, the diameter of the upper and bottom surface of the first-stage stirring needle D2=8mm, Bottom diameter D3=8mm, upper bottom diameter D4=4mm of secondary stirring needle, lower bottom diameter D5=4mm, end surface of primary stirring needle is convex, shaft shoulder diameter D1=18mm, stirring head speed 1400r / min, welding The speed is 600mm / min. The microstructure analysis of the welded aluminum alloy sheet is as follows: image 3As shown, the results show that the "HOOK" in the joint ...
