Example Embodiment
[0030] Specific implementation of self-fusion welding:
[0031] A. Put a Hastelloy C-276 plate with a thickness of 0.5mm on the clamp 3 and clamp it with copper clamps, the clamp spacing is 6mm. Place the preheating plate 2 on the workbench, and place a fixture 3 above the preheating plate 2 to fix the three positions.
[0032] B. Adjust the ultrasonic parameters. Adjust the ultrasonic head 7 so that it is 14 mm behind the welding position to ensure that the position of the ultrasonic head 7 acts on the preheated thermoplastic zone and can conduct ultrasound into the molten pool. Adjust the angle of the ultrasonic head 7 so that the axis of the ultrasonic head 7 is at an angle of 30° with the horizontal. Adjust the position of the ultrasonic head 7 so that its tip is 0mm away from the surface of the workpiece; after the position of the ultrasonic head 7 is determined, fix it with the machine tool cantilever to ensure that the relative position of the two does not change during th...
