大间隙钎焊工艺因素对接头成形与组织特性的影响

Effects of Technological Factors of Wide Clearance Brazing on Formation and Microstructure of Joints

本文研究了大间隙钎焊工艺因素对接头成形与组织的影响。研究表明,采用适当比例的金属粉的预置方式,可以获得稳定的优质接头。同时探讨了大间隙钎料的形成机理。

The effects of technological factors of wide clearance brazing, on formation and microstructure of jointsare investigated in this paper. It is found that the joints of stable high quality can be obtained by themetal fines preset type with suitable proportion. The formation mechanism of wide clearance brazing is discussed.
