摘要：
An improved metal-core weld wire, usable for joint and surface welding, having a steel sheath with a core, and a core composition disposed in the core of the steel sheath, wherein the core composition is between approximately 0.001-12.0% total weight of the metal-core wire. The metal-core wires of the present invention have improved manufacturability. In another embodiment, the core composition includes iron powder in an amount that provides an oxygen content less than approximately 600 ppm in the metal-core wire for producing weld deposits with improved impact strength properties.
