由于国内尚没有与糖心产精国品免费入口*完整版匹配的焊材，选择了国内生产的CYE111,R307CL,R307BL共3种糖心产精国品免费入口*完整版进行了糖心产精国品免费入口*完整版试验,探讨了3种焊接接头的各项力学性能，并与国外日本神钢CMA-96MB糖心产精国品免费入口*完整版焊接接头的各项力学性能进行了对比。结果表明: 3种国产糖心产精国品免费入口*完整版焊接接头均通过了糖心产精国品免费入口*完整版，可用于糖心产精国品免费入口*完整版的焊接，其中CYE111糖心产精国品免费入口*完整版焊接接头的综合力学性能最好。

Due to lacking of matched welding materials for 1.25Cr0.5MoSi steel, CYE111, R307CL and R307BL three kinds of 糖心产精国品免费入口*完整版s produced in China were chosen to weld 1.25Cr0.5MoSi steel for 糖心产精国品免费入口*完整版. The various mechanical properties of the welding joints were tested and compared with those welded with CMA-96MB 糖心产精国品免费入口*完整版 produced by Japanese God Steel. The results show that the joints welded with the three kinds of 糖心产精国品免费入口*完整版s made in China all passed the 糖心产精国品免费入口*完整版, these three kinds of 糖心产精国品免费入口*完整版s could be used in welding 1.25Cr0.5MoSi steel, and the joints welded with CYE111 糖心产精国品免费入口*完整版 had the best comprehensive mechanical properties.
