Welding tool and method for copper woven belt and copper lead

Abstract

The invention discloses a welding tool and method for a copper woven belt and a copper lead. The welding tool comprises an upper arc-shaped piece, a lower arc-shaped piece, a locking bolt and a connecting device. According to the welding tool and method for the copper woven belt and the copper lead, firstly, the copper woven belt and the copper lead are fixed through the welding tool, the whole welding process of the copper woven belt and the copper lead can be completed by one person, and the welding cost is low; secondly, the area, exposed to air, of the copper woven belt is reduced during welding, so that the oxidation degree of the copper woven belt is reduced, tin materials can be conveniently accumulated, and then welding flux at the welding position is dense and fastened; and finally, the copper woven belt is pressed during welding, so that one side of the copper woven belt is smooth and full during welding, burrs and other edges and corners generated during welding are reduced,the situation of pseudo soldering is avoided, the welded copper woven belt and the copper lead can be conveniently assembled, the workload of operators is reduced, and better use prospects are brought.

Description

technical field [0001] The invention relates to the field of copper braid and copper lead wire welding, in particular to a copper braid and copper lead wire welding method. Background technique [0002] In the hundred-ampere-level high-temperature superconducting current, the lower end of the lead wire is often connected in parallel with a piece of copper braiding tape, which is used for cooling and current shunting during quenching. The upper end of the copper braid and the lower end of the lead wire are soldered and welded to the copper rod, and the welding surface is a semi-cylindrical plane. [0003] In the past welding of copper braids and copper leads, welders used pliers, old irons, etc. for manual welding, and more than two people were required to cooperate during welding. The labor cost was relatively high, and the welding quality was poor. After welding, the copper braid and copper There will be virtual welding between the leads, and there will be more burrs, and ...

Problems solved by technology

[0003] In the past welding of copper braids and copper leads, welders used pliers, old irons, etc. for manual welding, and more than two people were required to cooperate during welding. The labor cost was relatively high, and the welding quality was poor. After welding, the copper braid and copper There will be virtual welding between the leads, resulting in more burrs, and the copper braid is more oxidized during welding, which does not meet people's requirements for use. Therefore, we propose a welding tool for copper braid and copper leads
