WELDING MATERIALS AND METHOD FOR WELDING THEREWITH

摘要

The present invention relates to filler metal, wherein a plurality of wire rods to be melted by a heat source in welding is provided in a bundle and a welding method using the same. The filler metal improves productivity by increasing the strength of a current to be used; improves welding efficiency by increasing welding speed; and deepens welding penetration by increasing the intensity of arc.
