AI Technical Summary
In existing technologies, the amount of welding deformation and shrinkage of aluminum alloy ships is difficult to control. Conventional jigs cannot meet the deformation requirements of aluminum alloy ships after welding, resulting in poor construction quality.
During the jig layout process, the jig reference plane and anti-deformation line type are determined according to the rib theoretical line diagram. The anti-deformation amount is increased to offset the welding deformation, including forming anti-deformation lines in the height and width directions and extending the welding shrinkage compensation amount in the length and height directions.
Effectively control the deformation of aluminum alloy ships after welding, meet construction requirements, reduce construction difficulty, and ensure the quality of ship construction.
