The cold wire is sheathed with the special heat shrink tube, the cold wire is welded with the hot wire, and the hot wire is sheathed with the special heat shrink tube. The welding method of the implicit joint includes the following steps: first, clean the workbench with a hair dryer; first, sheath the special heat shrink tube on the cold wire or the hot wire, dip the cold wire or the hot wire end with softened copper wire on borax powder, bake it with a hydrogen-oxygen welding machine to melt it on the surface of the cold wire or the hot wire, and then fix this end of the cold wire or the hot wire with a clip; weld the other end; grind it smooth after welding, and finally pull the pre-sheathed special heat shrink tube to the welding place and bake it with a hair dryer to attach it to the surface of the connection, and then cool it with clean water. The present invention melts a layer of borax at the welding part to improve the anti-oxidation ability, and sheaths a special heat shrink tube on the welding part, which enhances the strength of the joint by about three times.

[0009] Step 3, then immediately take the cold wire or hot wire at the other end and weld the two cold wires or hot wires together;

[0010] Step 4. After welding is completed, use a grinding wheel to grind the weld smooth and smooth, and rub it smooth with sandpaper. Finally, pull the special heat shrink tube that was put on in advance to the weld and bake it with a hair dryer so that it adheres to the surface of the connection, and then cool it with clean water.
