FLUX CORED WELDING WIRE AND ITS FABRICATING METHOD

摘要

A wire-shaped welding rod having flux and a manufacturing method thereof are provided to prevent leakage of flux which is received in a gap of joints, and to prevent generation of arc in welding. A wire-shaped welding rod comprises flux(10) and a circular core(102). The flux is filled in the center of the circular core. The circular core is covered by a rolled strip to a circular shape. An upper edge or a lower edge of the strip is molded to be inclined when the circular core is molded. The upper edge or the lower edge of the strip has a joint end which is adhered by inclined surfaces(100a,100b) without a gap.
