Method of packaging seamed flux-cored welding wire intermediate product and package of seamed flux-cored welding wire intermediate product

Abstract

A method of packaging a seamed flux-cored welding wire intermediate product in which a flux is filled in a mild steel outer shell includes the steps of forming a stacked product by depositing or winding a seamed flux-cored welding wire intermediate product around a central member in the form of a coil using the central member as the center, packaging the stacked product in a metal package together with a desiccant, and deaerating and sealing the metal package.

1 . A method of packaging a seamed flux-cored welding wire intermediate product in which a flux is filled in a mild steel outer shell, comprising the steps of:
 forming a stacked product by depositing or winding a seamed flux-cored welding wire intermediate product around a central member in the form of a coil using the central member as the center;   packaging the stacked product in a metal package together with a desiccant; and   deaerating and sealing the metal package.   
   
   
       2 . The method of packaging a seamed flux-cored welding wire intermediate product according to  claim 1 ,
 wherein a support plate for supporting the seamed flux-cored welding wire intermediate product is provided on at least one end of the central member, and   in the step of forming a stacked product, the stacked product is formed by depositing or winding the seamed flux-cored welding wire intermediate product around the central member in the form of a coil while the seamed flux-cored welding wire intermediate product is supported by the support plate.   
   
   
       3 . The method of packaging a seamed flux-cored welding wire intermediate product according to  claim 1 ,
 wherein, before the step of forming a stacked product, a lubricant for ensuring the drawability and holding oil for holding the lubricant are applied on the surface of the seamed flux-cored welding wire intermediate product.   
   
   
       4 . The method of packaging a seamed flux-cored welding wire intermediate product according to  claim 1 ,
 wherein the seamed flux-cored welding wire intermediate product has a diameter in the range of 2.0 to 5.5 mm.   
   
   
       5 . A package for packaging a seamed flux-cored welding wire intermediate product in which a flux is filled in a mild steel outer shell, comprising:
 a central member disposed at the center of a coil-shaped stacked product which is composed of a seamed flux-cored welding wire intermediate product and which is prepared using the central member as the center;   a metal package which packages the central member together with the stacked product and which is deaerated; and   a desiccant packaged in the metal package.   
   
   
       6 . The package of a seamed flux-cored welding wire intermediate product according to  claim 5 ,
 wherein a support plate for supporting the seamed flux-cored welding wire intermediate product is provided on at least one end of the central member.   
   
   
       7 . The package of a seamed flux-cored welding wire intermediate product according to  claim 5 ,
 wherein a lubricant for ensuring the drawability and holding oil for holding the lubricant are applied on the surface of the seamed flux-cored welding wire intermediate product.   
   
   
       8 . The package of a seamed flux-cored welding wire intermediate product according to  claim 5 ,
 wherein the seamed flux-cored welding wire intermediate product has a diameter in the range of 2.0 to 5.5 mm.
