brazing

1.The theoretical rules among the high temperature performance of the brazing alloy, strain rate and the function of Co alterant are analyzed.

分析了料高温性能与速率、钴的质剂作用等因素之间的理论规律。

2.Brazing quality and product reliability are both increased as using high frequency pulse microplasma arc heating process for assembly brazing of cathode and photoetching grid of electron tube.

采用高频脉冲微束等离子弧做为电子管阴和光装配工艺的热源,提高了缝质量和产品的可靠性.
