C. deck girder is installed;
D., right side floor is installed, then right side wall panel is installed;
E. end stringers is installed;
F. each deck is lifted successively;
5) areal survey and lower tire
Cutting stillborn foetus plate, then measures self-inspection;
Section non-allowance is rule;
Welding equipment hoisting tooling;
Under segmentation, tire stands up: by the handling of segmentation with stand up, and is placed on platform;
Outer backboard scratches welding: by outer back seam welds.
Further, the moulding bed in described step 3) is template type moulding bed, and often arranging moulding bed top is the spaced trapezoidal support end of a row.
Further, described step 2) in, to stand up in the direction non-perpendicular to weld seam when standing up for needing the sheet material standing up welding.
Further, in step 4), described outside plate and moulding bed should be adjacent to, and gap is less than 3mm.
Further, comprise the position of step 6) to subsection deformation and correct, mark segmented wheel profile, and the surplus outside outline line is cut.
Beneficial effect of the present invention is:
The present invention, by the reasonable setting to setting-up procedure, moulding bed carries out jointing line mark and realizes automatic welding, and overall block assembly efficiency and the welding quality improving bottom of ship, enhances productivity and enhance product performance and the life-span.
