热处理对硬质合金钎焊焊缝强度的影响

The Affection of Heat Treatment on the Strength of Brazing Weld of Cemented Carbide

硬质合金钎焊后进行淬火、回火处理,焊缝强度明显下降。本文分析了钎焊焊缝强度下降的原因,并提出改进措施。

After cemented carbide brazed is quenched and tempered, the strength of welding stam descend obviously.This paper analyses the cause of strength descent of brazing weld, and proposes improving measures.
