Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A welding wire for high-strength steel for improving slag coagulation, the welding wire essentially consisting of: in terms of weight percent relative to the total weight thereof, 0.09-0.11% C, 0.2-0.4% Mn, 0.3-0.65% Si, 0.03-0.04% Al, 0.05-0.07% S, 0.005-0.01% Se, and a remainder composed of Fe and impurities whereas such effects of narrowing ranges of a combination of elements improves slag coagulation. 2. The welding wire of claim 1 , wherein the weight ratio of Mn:Al:Si is 3:2:3. 3. The welding wire of claim 1 , wherein an Al—Mn—Si-based crystalline oxide is generated as slag resulting from a welding process. 4. The welding wire of claim 3 , wherein the Al—Mn—Si-based crystalline oxide is Mn3Al2Si3O12. 5. The welding wire of claim 1 , further forms a molten pool during a welding process, the pool flowing to a center portion in a width direction of a weld bead, thereby allowing a generated slag to be concentrated on the center portion.
