Metal powder welding material special for high-frequency welding machine

Abstract

The invention discloses a metal powder welding material special for a high-frequency welding machine. The metal powder welding material comprises the following components in percentage by weight: 40-65 percent of Cu, 25-50 percent of Zn, 4-6 percent of KBF4, 2-3 percent of H3BO3 and 2-3 percent of Sn. The metal powder welding material special for the high-frequency welding machine provided by the invention can be suitable for welding diamond tools, alloys or other shaped pieces and the like, and has the advantages of wide application range, low melting point, high welding strength and capability of effectively ensuring the product quality of weld assemblies; and meanwhile, the use of precious metals such as silver and the like is avoided, so that the welding cost is lower.

Description

technical field [0001] The invention relates to the technical field of welding material preparation for high-frequency welding machines, in particular to a special metal powder welding material for high-frequency welding machines. Background technique [0002] Diamond saw blades have been widely used in stone, ceramics and glass processing industries. Diamond saw blades are composed of multiple diamond blades welded on a steel substrate at certain intervals. In the prior art, the brazing sheet is manually laid on the saw teeth of the diamond saw blade, and the cutter head is welded on the diamond saw blade by using the brazing sheet. Place the chips on the sawtooth and align them, and the placed brazing chips are easy to be blown off by the wind, which affects the welding effect and efficiency. In addition, there are some silver-based fiber solders in use. The disadvantage is that the demand for silver solder is large, and the cost of silver is high. A large amount of silve...

AI Technical Summary

Problems solved by technology

In the prior art, the brazing sheet is manually laid on the saw teeth of the diamond saw blade, and the cutter head is welded on the diamond saw blade by using the brazing sheet. Place the sheet on the sawtooth and align it, and the placed copper sheet is also easy to be blown off by the wind, which affects the welding effect and efficiency

In addition, there are some silver-based fiber solders in use. The disadvantage is that the demand for silver solder is large, and the cost of silver is high. A large amount of silver solder will not only increase the welding cost of diamond saw blades, but also cause a shortage of silver resources. shortage

For some other copper solders, its melting point is high, and it is easy to cause carbonization on the surface of the diamond blade when welding the diamond saw blade, and it is difficult to correct the serious deformation of the steel matrix, and the quality of the welded product is extremely poor.
