1·And their heating means are different, such as furnace brazing, induction brazing and laser brazing.

按加热方法来分，有炉中钎焊、激光钎焊和感应钎焊等。

2·The test samples of brazed diamond tool are prepared by the high-frequency induction brazing technology under the conditions of different brazing time and vacuity.

利用高频感应钎焊技术，在不同的钎焊时间和真空度条件下制备金刚石工具试样，在自制的装置上测试试样单颗金刚石磨粒的剪切破坏力大小。

3·By adoption medium frequency induction brazing, we eliminate the problems in the flame brazing. This gave us data that we use medium frequency induction brazing in the subsequent productions.

通过采用中频感应钎焊消除了气体火焰钎焊焊接转子并头套的缺陷，为后续产品采用中频感应钎焊焊接线圈并头套提供了依据。

4·A novel supersonic induction heating supply is researched, which is suitable for large-area generatrix brazing.

对高频感应加热电源中的线圈进行了研究与设计。
