Abstract

A thermo-melting solder for the thermo-melting welding between copper wire and structural member is composed of the thermo-melting welding stock which contains less Zn and Sn for generating CuZnSn alloy at welded point and excessive Al for removing surficial oxide from welded point, and the igniting agent containing potassium permanganate instead of potassium bichromate (or chloride).

Description

1. Technical field [0001] The present invention relates to the welding material used in metal welding, more specifically, the present invention relates to the hot-melt solder used for welding metal by high-temperature hot-melt welding method, ignition agent and the composition of hot-melt solder and ignition agent hot melt solder. 2. Background technology [0002] There are a large number of connections between wires, between metal components, and between wires and components in wired signal transmission projects such as communication systems using railway guide rails or long-distance transportation pipelines as wires, lightning protection grounding projects for field buildings and structures, etc. solder joints. The traditional welding method is arc welding or gas welding. However, due to the wide distribution of these connection and welding points in the field, limited by the transportation of power supply and welding equipment, the construction is often inconvenient, an...
