Abstract
Description

[0002] As an important part of the equipment manufacturing industry, welding technology is a key link in shipbuilding, running through the entire process of hull structure connection.
[0003] In shipbuilding, irregularly shaped components such as T-tubes, K-tubes, and Y-tubes are widely used in hull frames and piping systems. These components consist of a main pipe and auxiliary pipes, with complex structures and significant differences in dimensions, the angle between the main and auxiliary pipes, and their bending patterns among different specifications. Currently, the industry uses a manual-assisted welding process for welding these components. The specific procedure is as follows: First, the main pipe is placed stably on the welding worktable and clamped and fixed using a main fixing fixture. Then, the operator manually adjusts the position of the auxiliary pipe and clamps it again using an auxiliary fixture.
