EXPERIENCE OF MANUFACTURE AND APPLICATION OF SEAMLESS FLUX-CORED WIRE FOR ELECTRIC ARC WELDING

V.N. SHLEPAKOV and A.S. KOTELCHUK

E.O. Paton Electric Welding Institute, NASU, Kiev, Ukraine
 
 
Abstract
Design features of seamless flux-cored wires designed for electric arc welding are considered. Their technical and economic advantages and disadvantages have been analyzed. Process flowsheets of manufacturing seamless flux-cored wires with filling of the pre-welded tubular billet, as well as with continuous filling of U-shaped profile of tube billet with subsequent welding of wire sheath longitudinal butt are described.
 
 
Keywords: electric arc welding, seamless flux-cored wire, flux-cored wire manufacturing technology, its advantages and disadvantages
