Problems solved by technology

In addition, due to the high requirements on the bearing capacity of the flange, the plate thickness of the flange base is relatively thick, and the overall flatness is extremely high.
Due to the thick plate thickness, large amount of welding, and concentrated thermal stress, the flange base plate is easily deformed, exceeding the allowable deviation range of flatness
[0003] For the jigsaw operation of such large and ultra-thick flanges, there are no clear control procedures and construction methods, and there are many hidden dangers in the construction process, and the problem of overall flatness out of tolerance is very easy to occur

Abstract

The invention discloses a flange connecting method, and belongs to the technical field of shipbuilding. The flange connecting method comprises the steps of S1, manufacturing a bed jig assembly for placing jointed boards; S2, placing the jointed boards onto the bed jig, and assembling; and S4, welding a groove between each two adjacent jointed boards so as to form a flange, and during the welding process, monitoring the deformation of the flange in real time. Through arranging the special bed jig assembly for placing the splicing boards, the problem of instability in flange connection due to unqualified jointed board assembly caused by instable placement is avoided; and meanwhile, through monitoring the deformation of the flange in real time during the welding process, the corresponding measures can be taken when the deformation exceeds a predetermined value, so that the aim of improving the first-pass yield of the flange precision quality is achieved, and unnecessary repair caused by poor control of a middle process is avoided.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a flange connection method. Background technique [0002] For ships using azimuth propellers as propulsion methods, the propulsion base usually adopts flange form. Due to the large overall size of the flange, jigsaw work is required. Moreover, due to the high requirements on the bearing capacity of the flange, the thickness of the flange base plate is relatively thick, and the overall flatness requirement is extremely high. Due to the thick plate thickness, large amount of welding, and concentrated thermal stress, the flange base plate is easily deformed, exceeding the allowable deviation range of flatness. [0003] For the jigsaw operation of such large and ultra-thick flanges, there are no clear control procedures and construction methods. There are many hidden dangers in the construction process, and the problem of overall flatness is very easy to appear. [0004] Ther...
