摘　　要：本文通过对焊芯合金含量和药皮组成物的分析,设计了一种高熔敷效率铁粉焊条配方。采用该配方试制的焊条,不仅具有良好的操作工艺性,而且熔敷金属扩散氢含量低,焊缝金属具有良好的强韧性匹配。Based on analysis of alloy elements content of core wire and coating composition, a kind of electrode with high deposited efficiency is designed. The electrode has not only good usability but also low diffusible hydrogen, and the weld metal has matched strength and toughness.
