Embodiment Construction
[0028] The present invention will be further explained below in conjunction with the accompanying drawings and embodiments.
[0029] Such as figure 1 , figure 2 , image 3 As shown, a semi-submersible underwater rotary magnetization friction stir welding tool includes a stirring head body 1, and the stirring head body 1 includes a magnet bias device 2, a clamping assembly 3 and a water cooling assembly 4, and the magnet bias One end of the device 2 is sleeved in the clamping assembly 3, and the magnet bias device 2 is provided with a water-cooling assembly 4; the magnet bias device 2 includes a shaft shoulder assembly 201 on the stirring head and a shaft connected to the stirring head by a motor. The lower shoulder assembly 210 of the stirring head connected to the shoulder assembly 201 and the magnet bias device 2 greatly reduce the welding load and prolong the service life of the stirring head; when a strong rotating magnetic field is applied in the welding process, an el...
