[0051] The spraying process of the electromagnetic spray head and the electromagnetic spraying device of the present application will be described in detail below:

[0052] Spraying the metal pipe and the casing shell: The power drive unit drives the autonomous vehicle 200 to move beside the metal pipe and the casing workpiece. The controller 500 controls the rotation and lifting of the robotic arm 400 base and the robotic arm 400 assembly to position the electromagnetic spray head at the place to be sprayed.

The controller 500 regulates the angle of the nozzle to achieve omnidirectional spraying, and regulates the magnetic field of the electromagnetic field emitter to change the arrangement of the filler, so that the filler is parallel to the inner wall surface of the pipe. In this application, by controlling the extension of the robotic arm 400, omnidirectional spraying of the inner wall of the metal pipe and the casing is achieved.
