Flux-cored wire for stainless steel arc welding

   
   

A flux-cored wire for stainless steel arc welding having flux filled up in an outer metal sheath made of stainless steel, comprises: as percentage to total weight of the wire, TiO.sub.2 5.5 through 10.0 mass %, SiO.sub.2 1.5 through 3.0 mass %, Al.sub.2 O.sub.3 0.5 through 1.5 mass %, and fluorine compound (by a value expressed in terms of fluorine) 0.10 through 0.15 mass %, and an amount of ZrO.sub.2 is limited to no more than 0.1 mass %, and it has a flux rate of 25 through 45%, and a total amount of slag forming ingredient is 8 through 14 mass % as a percentage to total weight of the wire, and thereby to provide excellent welding workability especially in welding of a thin sheet stainless steel.

Un alambre flujo-quitado el corazo'n para la soldadura de arco del acero inoxidable que hace flujo llenar para arriba en una envoltura externa del metal hecha del acero inoxidable, abarca: como porcentaje para sumar el peso del alambre, % total de TiO.sub.2 5.5 a 10.0, % total de SiO.sub.2 1.5 a 3.0, Al.sub.2 % totales de O.sub.3 0.5 a 1.5, y % totales del compuesto del flúor (por un valor expresado en términos del flúor) 0.10 a 0.15, y una cantidad de ZrO.sub.2 se limita a no más de 0.1 % total, y tiene un índice del flujo de 25 a el 45%, y una cantidad total de escoria que forma el ingrediente es 8 a 14 % totales como porcentaje para sumar el peso del alambre, y de tal modo para proporcionar workability excelente de la soldadura especialmente en la soldadura de un acero inoxidable de la hoja fina.
