Abstract

By improving the welding temperature of friction stir welding, two magnets were arranged symmetrically around the stirring head, taking the 1 mm thick 6061-T6 aluminum alloy sheet as the research object by HR-FSW (High Rotation Friction Stir Welding) assisted by a magnetic field. When the magnets were accompanied by the high-speed rotation of the stirring head, a changing magnetic field would be generated on the aluminium plate, thus generating an eddy current effect. An iron plate was placed under the aluminum plate to shield the induction magnetic field diffusion. Ansys-Maxwell software was used to simulate the electromagnetic force change and eddy current heat loss power of the induced magnetic field in the welding process. The experiment was carried out by the thermocouple method. 7 points were taken on the forward side, the core area, and the backward side of the aluminium plate, and the maximum welding temperature of each point was measured. The results show that the induced magnetic field produced by rotation has an eddy current thermal and mechanical effect on the aluminum alloy sheet. The temperature increases most obviously in the preheating stage, which can improve the preheating efficiency and welding temperature.
