Unless otherwise stated, the meaning of "multiple" is two or more.
[0032] In the construction site, there is often a need to stagger-weld two elongated members, such as stagger-welding copper flat strips or copper stranded wires with steel bars. In the related art, in order to ensure the construction efficiency and simplify the construction process, a welding mold which can open and close is used to wrap the copper flat strips or copper stranded wires, and then one side of the steel bars is attached to the welding mold, and the other side of the steel bars is covered with soil to seal the welding mold, so that a closed welding cavity is formed at the staggered position of the copper flat strips or copper stranded wires and the steel bars, and the welding cavity is filled with solder to weld the two members. However, due to the fact that the mold cannot completely wrap the welding position, the molten solder is easy to leak from the welding cavity during welding, which leads to welding failure. In addition, when using this process to weld, the water in the soil will contact the hot solder and generate a large amount of water vapor, which will cause the formed joint to have dense pores, resulting in unqualified welding.
[0033] Based on this, the utility model provides a kind of welding mold, by setting two opposite modules, the closing face of two modules is equipped with welding cavity and multiple first pass in the welding cavity position intersection, wherein first pass at least one end penetrates welding mold, when welding, welding piece is installed in first pass, so that welding position is located in welding cavity, after closing of two blocks module, by filling welding cavity with heat release reaction Filling solder.
