高温钎焊是钎焊工艺体系形成的重要部分,本文通过对当前高温钎焊中存在的焊接温度偏低、工艺级数少等问题进行分析,提出了一种新的钎料分配方案和级数调整方法。高温钎焊温度由原来的1060℃提高到1160℃,级数由原来的仅有一级变成现在的三级,各级数之间温度梯度合理。该方案可实施性好,能有效提高焊缝质量,并完善焊接工艺。 High-temperature brazing is an important part of the formation of brazing process system. Based on the analysis of the problems of low soldering temperature and few process steps in the current high-temperature brazing, a new brazing material distribution scheme and series Adjustment method. High temperature brazing temperature from the original 1060 ℃ to 1160 ℃, the number of levels from the original only into one of the current three, the temperature gradient between the various levels reasonable. The program can be implemented well, can effectively improve the quality of the weld, and improve the welding process.
