[0018] See Figure 1-Figure 4 , Make a truncated cone-shaped barrel wall of appropriate size, bottomless up and down, with a small bottom facing down, and leave four appropriate wide brackets at the bottom center and cross-symmetric positions for fixing the excitation coil. The four coils are of the same height, and the central axis is facing the center of the circle, and the two facing each other are divided into two groups. Two symmetrical brackets are installed on the upper part of the big end of the barrel wall, and the middle center part is used to fix it on the welding gun. The above two sets of coils are respectively connected to the excitation power supply through a waveform shifter, and the two sets of coils are adjusted to be connected to synchronous sine alternating current and cosine alternating current respectively. After energization, a magnetic field parallel to the axis of the coil is generated in the middle of each group of coils. This magnetic field also chan...
