摘　　要：研制了TIG焊进行SA2 13 -T91钢底层焊道焊接专用的新型药芯焊丝。该焊丝的焊接工艺性能和力学性能优良。在SA2 13 -T91钢根部TIG焊打底时 ,用该焊丝焊接 。A new kind of flux-cored wire, specially designed for TIG root bead welding of SA213-T91 steel, has been successfully developed. This kind of flux-cored wire has both excellent welding procedure properties and satisfactorg mechanical properties. TIG welding to SA213-T91 using this kind of wire does not need argon shielding in the back of the weld.
