Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a welding positioning device for ship structures. Background Technology

[0002] A ship's structure mainly consists of the hull, decks, and bulkheads. The hull is the outer shell of the ship, acting as a protective shield to protect it from seawater pressure and external impacts. The deck carries personnel, cargo, and equipment, while also providing work and activity space. The bulkheads divide the ship's interior into different compartments, providing waterproofing, fireproofing, and other functions to ensure the ship's safety and functionality.

[0003] Welding is crucial in shipbuilding, especially on the ship's sides. The hull and walls are typically welded from curved steel plates with a specific curvature. Due to their unique curved structure, traditional positioning devices used for welding flat steel plates are difficult to precisely adapt, hindering effective and stable positioning of the curved steel plates. This results in insufficient stability during welding and affects welding accuracy. Therefore, we propose a welding positioning device for ship structures. Utility Model Content
