A brazing process

Abstract

A brazing technique includes the following steps that firstly, a first welded element and a second welded element which are to be welded and a brazing material are provided; secondly, the welded elements are pretreated; thirdly, the brazing material is injected in welded portions of the first welded element and the second welded element; fourthly, the first welded element and the second welded element which are injected with the brazing material are kept fixed and heated and cooled through a heating device, wherein the heating temperature does not exceed 180 DEG C; and fifthly, the welded elements are subjected to aftertreatment. By the adoption of the provided brazing technique, low-temperature brazing of materials such as a metal aluminum alloy composite material, ceramics and glass can be achieved; and the utilized brazing material is high in heat conducting coefficient, operation is convenient and rapid, the technique is simple, cost is low, the pass percent of brazed products is effectively increased, and the production cost is reduced.

Description

Technical field [0001] The invention belongs to the technical field of welding, and specifically relates to a brazing process between inorganic non-metallic materials. Background technique [0002] In the prior art, the assembly process between the light source assembly and the lamp housing of the LED bulb lamp is generally a series of assembly process methods such as gluing, fusion sealing and snapping. Traditionally, the lampshade is bonded to the base by glue. Although the cost is low and the process is simple, the temperature resistance is poor, and it is easy to crack and fall off after the lamp is heated for a period of time. As for the high-temperature melting and sealing technology, in such a high-temperature environment, the external lead electrode is fixed by bonding, and it is very easy to separate from the base and cause a dead light. [0003] The brazing process is generally considered to be able to make up for the technical defects of the process types such as glue, ...

AI Technical Summary

Problems solved by technology

However, most of the existing brazing processes are only applicable to metal materials. In recent years, some inorganic non-metallic materials have gradually appeared using brazing welding processes, but they all have considerable process difficulty and high cost.

[0004] In particular, some brazing processes are in a high-temperature environment during the over-flow soldering process. When the welding involves the assembly process of the shell of the lamp, because the LED light source components have been packaged inside the shell, the high-temperature environment will cause damage to the LED light source. Therefore, in this The high temperature brazing process is not applicable under the process
