研究了感应钎焊时，不同钎焊参数对零件内外表面温度的影响，分析了钎焊工艺参数对母材组织和接头质量的影响。缓慢升温可使工件内外表面温度达到平衡，钎焊温度在780℃以下，保温时间小于20 s的工艺参数可获得优良钎缝和不损伤母材组织。
The influence of different induction brazing parameters on the temperatures of the inner and external surfaces of the workpiece was mainly discussed, and the influence of brazing parameters on base material microstructures and joint quality was analyzed. The results show that the temperature difference between the inner surface and external surface of the workpiece can be minimized when the temperature is increased slowly.On the conditions of brazing temperature not higher than 780℃ and holding time of lower than 20 seconds, excellent brazing seam can be achieved and base material microstructures are not damaged.
