摘　　要：介绍了SA2 13-T91钢用药芯焊丝的研制。此焊丝的工艺性能良好 ,适用于全位置焊接 ,熔敷金属的力学性能达到SA2 13-T91钢的要求。与进口实芯焊丝相比 ,用于底层焊道焊接时 ,可实现熔池背面的熔渣保护 ,不必采用繁杂的背面充氩保护工艺。该药芯焊丝可替代进口实芯焊丝使用。Development of fluxcored welding wire with SA213T91 steel as base material is introduced. It has good technical performance, and is suitable for all position welding. The mechanical characteristics of the welding attached metal meet the requirement of SA213T91 steel. Comparing with imported solid welding wire, this newly developed product can realize the back slag protection for melt well when used for bottom bead welding, thus the complex backside argon protection procedure is no more needed. This fluxcord welding wire can be used in place of imported solid welding wire.
