Abstract
A welding wire for high-strength steel for improving slag coagulation includes a combination of Carbon, Manganese, Silicon, Aluminum, Sulfur, and Selenium. With use of the welding wire, the generation of slag is minimized, and the slag is allowed to induce the generation of crystalline oxides having a low surface energy, so that the slag is easily removed, and the flow of a molten pool to the center in a width direction of a weld bead do that the slag is coagulated.
