Problems solved by technology
[0008] The feature of this method is that three non-ferrous metal strips are fixed by laser spot welding at intervals to form a semi-finished bimetallic strip with copper strips on both sides and the side ends of the middle manganin-copper strip, which facilitates the clamping of electron beam welding. It also simplifies the tooling structure used in electron beam welding. It only needs to clamp and fix the two edges of the above-mentioned semi-finished bimetal belt to carry out electron beam welding, which solves the problem of electron beam welding giving way to the weld seam and effectively prevents electron beam welding. The product deformation caused by high energy during beam welding leads to the deviation of the welding seam, which ensures the quality of the welding seam. Strip welds are welded at one time, improving production efficiency

Embodiment 1
[0028] Such as figure 1 , figure 2 , image 3 As shown, the welding method of the bimetal strip of the electronic energy meter shunt described in this embodiment cuts the non-ferrous metal into strip-shaped non-ferrous metal strips of the described thickness;
[0029] The first step is to cut the non-ferrous metal into strip metal strips with a thickness of 2.5mm. The middle non-ferrous metal strip is a manganese-copper non-ferrous metal strip 1. The width of the manganese-copper non-ferrous metal strip 1 is 6.0mm, and the two sides are copper Non-ferrous metal strip 2 with a width of 15.0mm, two copper non-ferrous metal strips 2;
[0030] In the second step, put the three cut non-ferrous metal strips into the laser welding mold, and place the manganese-copper non-ferrous metal strip 1 in the middle, and the two sides of the manganese-copper non-ferrous metal strip 1 are the copper non-ferrous metal strip 2 and the manganese-copper metal strip 2 The two sides in the length...

The invention discloses a non-ferrous metal welding method and particularly relates to a welding method of different metals in non-ferrous metals for manufacturing an electronic type electric energy meter shunt. For overcoming defects in the prior art, a welding method of an electronic type electric energy meter shunt bimetal strip is high in welding speed, welded metals are convenient to install, product quality is high in consistency. The welding method includes that a strip-shaped non-ferrous metal strip is processed according to requirements, a bimetal strip is obtained through laser spot welding and electron-beam welding, and a shunt can be obtained by performing pouching shear on the bimetal strip according to requirements. The welding method is widely applied to existing electronic type electric energy meters, and the welding method of the electronic type electric energy meter shunt bimetal strip has the advantages of being convenient to operate, reducing cost and the like.
Description
technical field [0001] The invention relates to a welding method of nonferrous metals, in particular to a welding method of different metals in the nonferrous metals used for manufacturing electronic energy meter shunts. Background technique [0002] The energy problem is the theme of the world. In order to save more electricity, higher requirements are put forward for the electronic energy meter --- low loss, energy saving, and accurate measurement. The first revolution in the electronic energy meter is the adjustment of the structure of the shunt. For example, the patent number of the Chinese patent is ZL200620007181.1, which discloses an electronic energy meter shunt. The appearance of the shunt makes the electric energy The meter not only reduces the raw material cost of the shunt, reduces the overall resistance and power consumption, but also makes the measured data more accurate. It can be seen from the patent that the shunt is composed of three pieces of two types of...
