本文包括真空扩散焊国内外发展概况、超高真空扩散焊机的构造和性能、操作规程、焊接工艺试验,对本台设备的评价五个部分内容。文中详细叙述了设备的各组成系统,强调了区别于普通真空炉的一些特点,并对本台焊机进行了简单的评价,也和国外同类焊机进行了简单的对比。认为这台设备既能实现超高真空,又能加热加压,适用范围较广。同时,作者在纵观真空扩散焊国内外发展的基础上,提出了理想的扩散焊机的发展趋势。
This article includes five parts of the development of vacuum diffusion welding at home and abroad, the structure and performance of ultra-high vacuum diffusion welding machine, operating procedures, welding process test, evaluation of this equipment. The paper describes the components of the system in detail, emphasizing some of the characteristics different from the ordinary vacuum furnace, and a simple evaluation of this machine, but also with foreign similar welding machine for a simple comparison. That this device can achieve ultra-high vacuum, but also heat and pressure, a wide range of applications. At the same time, on the basis of reviewing the development of vacuum diffusion welding at home and abroad, the author put forward the development trend of ideal diffusion welding machine.
