A method for butt joint assembly of side sections with knuckle positions and slot-shaped compartments

Abstract

The invention discloses a butt joint assembly method of a side section with a knuckle position and a trough-shaped compartment section. The inner longitudinal wall of the side section includes a first plate and is connected with the first plate at a predetermined angle. The second board, the assembly method includes: marking the first installation line and the first inspection line on the frame surface of the first board; rebutting the first installation line and the first inspection line to the cargo tank surface of the first board, Form the second installation line and the second inspection line; weld and assemble the first plate to the side section according to the first installation line and the first inspection line, pre-assemble the second plate to the side section; erect the laser instrument. The invention can simply and efficiently realize the accurate butt joint assembly of the internal carbon steel channel and the stainless steel channel at the knuckle position of the linear side section, and quickly check the butt joint accuracy of the channel structure of the linear side section. While satisfying the precision of ship construction, avoid a large number of non-destructive testing operations, shorten the ship construction cycle, and reduce production costs.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a butt joint assembly method for side sections with knuckle positions and slot-shaped compartment sections. Background technique [0002] The internal areas of chemical tanker cargo tanks are all made of stainless steel, and a large number of horizontal grooved compartments are used to divide the cargo tanks. The carbon steel grooves inside the side sections need to be accurately connected with the stainless steel grooved sections. Once there is a large deviation in the butt joint structure during the construction process, it will lead to problems such as insufficient butt joint strength, weld cracking, and stress corrosion of stainless steel, resulting in huge waste of repair costs. Due to the linear area of ​​the bow and stern, the side section is not a straight structure, and the inner longitudinal wall of the section has oblique inclination angles in two dire...

Once there is a large deviation in the butt joint structure during the construction process, it will lead to problems such as insufficient butt joint strength, weld cracking, and stress corrosion of stainless steel, resulting in huge waste of repair costs

Due to the linear area of ​​the bow and stern, the side section is not a straight structure, and the longitudinal wall of the section has oblique inclination angles in two directions. At the same time, the sections on both sides of the knuckle cannot draw a unified baseline at one time.
