seam chink fill method of flux cored wire and seam chink filling device for the method

摘要

The present invention is a liquid seams molded at a fraction of the forming machine and drawing machine, drawing a flux-cored wire by coating and heating the resin to a cleaning and sealing, the coating material prepared in the flux cored wire having the seam gap sealing to the inner layer in the filled flux leakage through the gap or seam so as to prevent moisture absorption which can further improve the weldability. provides a method and apparatus for sealing the joint gaps him. ; flux cored wire having the seam gap sealing layer manufacturing method of the present invention, the coating material (7) filling the flux (8) inside the mold, In the production method of the flux cored wire to drawing, using the drawing machine (4) and the spooler (5), the sealing device 10 is provided between the supply from the drawing machine (4), the flux traveling toward the spooler (5) the liquid resin on the outer peripheral surface of the cored wire and the joint gap (7a) and the step of coating is coated in the coating section 20 of the sealing device (10); A heating step of the liquid resin adhesive coated on the outer peripheral surface and the flux-cored wire joint gap (7a) and dried at the heating section 30 of the sealing device (10) and; The resin adhered to the outer peripheral surface of the flux cored wire is provided with a cleaning step of removing the cleaning part 40 of the sealing device 10 to form a sealing layer (7b) of a resin adhesive in the seam been slit (7a) . Seam gap sealing device for the manufacture of a flux-cored wire having such a seam gap sealing layer has a coating portion 20 and the heating unit 30 and the cleaning part (40).
