[0035] When the present invention is used: after the entire welding equipment is fixed in a suitable position, the plate suction mechanism provided on the main base 1 and the fixed side plate 5 of the welding equipment can adsorb and fix the welding plate 34, and the four first electric push rods 4 of each plate suction mechanism are adjusted to adjust the angle of the welding plate 34 adsorbed on the top thereof, so that two welding plates 34 waiting to be welded are close to each other and form a welding seam position 35;

[0036] The welding process of the welding plate 34 of the welding equipment is divided into two steps: wire placement and blow welding. In the wire placement process, the welding wire is transported to the wire outlet pipe 23 through the wire inlet pipe 24 at the top, and the welding wire is discharged through the rotation of the wire placement rotating seat 33 and the wire outlet pipe 23.

The laid-out welding wire 361 in the wire-setting state is fixed on the weld position 35; then the blow welding process is carried out. During the blow welding process, the blow welding host 21 works, and high-temperature gas is blown out through the blow welding air pipe 22 at the bottom, which acts on the wire-setting position to melt the welding wire by high temperature to achieve welding. When the high-temperature blow welding gas acts on the welding wire 361 in the wire-setting state and the wax block 371 in the wire-setting state, the welding wire and the wax block are melted due to the high temperature. Since the metal welding wire is heavier, the melted welding wire is located at the bottom to form the welding state welding wire 362, and the wax liquid covers the top to form the welding state wax layer 372, and the two welding plates 34 are welded together.
