Abstract

PURPOSE:To manufacture the flux cored wire for welding a multiple tube by forming a band steel in semicircular arc shape with forming roll group, inserting a flux cored inner tube and hand-shaped adding material inside a semicircular arc shape band steel as well and performing a wire drawing as an integrated multiple pipe. CONSTITUTION:In manufacturing the flux cored wire for welding a multiple tube used for welding a low temp. steel, low alloy steel or high alloy steel, a band steel (h) is delivered from a supply stand S, and its sectional shape is formed in a circular shape 3 from circular arc shape 2 with forming roll groups 1-4 in order. At the time of its being formed in semicircular arc shape the inner pipe IP filled with the adding material AM of a linear or hand like Cr, Mo, etc., and a flux F is fed at the same speed as that of the band steel (h) steel and inserted onto the inner face of a semicircular arc shaped strip steel. It is subjected to a wire drawing by wire drawing devices 5-7, the multiple tube shape welding wire having the strip steel (h) as its sheath and incorporating the flux cored inner pipe IP and adding material AM is stably manufactured and wound on a winding machine 8.
