Problems solved by technology
There are many defects in the existing ordinary welding, which are mainly divided into two aspects. One is internal defects, which are reflected in the presence of air holes, slag inclusions, internal cracks, incomplete penetration and internal fusion, etc.; the other is external defects. , There may be undercuts, weld bumps, arc craters, surface pores, slag inclusions, surface cracks, and unreasonable weld positions at the welding position of the two metals
In addition, when using ordinary welding to weld metal, there is always a performance difference between the welded part and the original metal material, so the quality of ordinary welding is mostly low

The invention discloses a high-frequency hot melting welding device and a welding method. The device comprises a welding part and a welding control system. The welding part comprises a material cylinder, wherein the outer part of the material cylinder is sequentially divided into a first heat treatment area, a hot melting area and a second heat treatment area; and a first high-frequency coil is wound on the first heat treatment area, a second high-frequency coil is wound on the hot melting area, and a third high-frequency coil is wound on the second heat treatment area. The welding control system comprises a single-chip microcomputer, and the signal output end of the single-chip microcomputer is respectively connected with the first high-frequency coil, the second high-frequency coil and the third high-frequency coil through a current processing circuit. Meanwhile, the invention also relates to the welding method for high-frequency hot melting. According to output signals of the single-chip microcomputer, the current is controlled, different currents are provided to the high-frequency coils at different times, then different heating temperatures are provided for to-be-welded metalelements, to-be-welded metal materials can be subjected to hot melting and heat treatment, and the welding quality of the metal materials can be greatly improved.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a high-frequency hot-melt welding device and a welding method. Background technique [0002] Metal welding is a fabrication or sculptural process of joining metals; during welding, the workpiece and the solder melt or do not melt to form a material-direct joining weld. There are many defects in the existing ordinary welding, which are mainly divided into two aspects. One is internal defects, which are reflected in the presence of air holes, slag inclusions, internal cracks, incomplete penetration and internal fusion, etc.; the other is external defects. , There may be undercuts, weld bumps, arc craters, surface pores, slag inclusions, surface cracks, and unreasonable weld positions at the welding position of the two metals. In addition, when metal is welded by ordinary welding, there is always a performance difference between the welded part and the original metal material, so ...
