Application Research about Vertical Welding Technology of Thick Steel Plate

FengLan Wang    

Abstract: Welding method of vertical seam welding in super thick steel plate (100~120 mm in thickness) is the traditional electroslag welding. The weld mechanical properties are bad and the method is gradually phased out. The emerging monofilament electrogas welding technology of vertical welding in 80 mm below has the high quality advantage. It is a practical technology to expand the electrogas welding technology to the super thick plate in current welding field. In this study, the technical problems faced are analyzed in vertical seam welding of the super thick steel plate. Under the bold innovation, the method and the experimental process by using double electrogas welding method to solve vertical sewing of the super thick steel plate are introduced. Some beneficial experience is summarized. The new technology is a good attempt for exploring high quality and efficient welding method of super thick plate welding.
