Products: flat line segments: shipbuilding equipment is important for the manufacture of the hull segment. Plane production line segmentation process outlined: 1, in place to complete the puzzle board welder column positioning assembly, with manual welding points; 2, on board the positive column welding, turning, negative welding, automatic dual-wire submerged arc welding; 3, according to the profile of the column position on the plate requirements, the rotation of the plate column, and the surface-crossed, to prepare for the installation profile; 4, the longitudinals assembly station will be mounted on the plate column profile, including profiles tack welding; 5, the profile of the installed automatic welding; 6, part of the finished assembly and welding longitudinals plate column is removed by sliding station; 7, ribs, girders plate mounted on the plate column, for ribs, girders plate tack welding; 8, installed on the ribs, girders plate welding; 9, the outer plate mounted on the plane segment, external plate tack welding; 10, the installation and tack welding After the outer plate welded to complete three-dimensional segmentation; 11, in jacking station stereo segmented top, with a heavy-duty vehicles (plant equipment) will be welded lifting out of the three-dimensional segmentation pipeline.
