heating after welding的意思|示意

The results show that toughness of the coarse grained HAZ is improved after second welding heat cycle except intercritical two-phase heating.

力学性能测试结果表明，除在临界二相区加热外，二次热循环均使粗晶区得到初化。

With the methods of the pre-heating before welding, controlling the interlaminar temperature and the heat treatment after welding, the welds that satisfy the quality specifications can be available.

通过焊前预热、层间温度控制及焊后热处理等手段获得了满足质量要求的焊缝。

The techniques for repair are studied after crack arrest in metal dies using electromagnetic heating, such as electrical spark melt joining, reinforced build-up welding and brush electroplating.

研究了各种实际金属模具中裂纹电磁热止裂后的修复技术，如电火花放电熔焊搭桥、强化堆焊、刷镀等；
