Problems solved by technology
When welding the curved surface segmented hull in step 3, since the weld seam is not on the horizontal plane and the slope of the weld seam is constantly changing, submerged arc automatic welding cannot be used, so manual welding is often used when welding the curved surface segmented hull. However, due to the inconsistent level of manual welding, it is easy to cause inconsistent quality of welded finished products

The invention relates to the field of welding, and in particular, discloses a ship hull surface welding method. A welding device is used in the method, and can control rotation of an impeller through adjusting the displacement of a gas pump; the rotating impeller drives a first rotating rod, a driving belt wheel, a driven belt wheel and a second rotating rod to rotate; then, a second belt wheel drives a groove wheel to move in a guide groove to realize power conversion and transmission; gas discharged by the gas pump can enable a cylinder rod to relatively move so as to realize control of the extension length of an extension rod; in the welding process, a pressure sensor arranged on a roller can return the pressure suffered by the roller; and then, a processor processes signals, and controls the displacement of the gas pump to keep stable pressure suffered by the roller, so that the welding process of the welding device is kept stable. The ship hull surface welding method can quickly and uniformly weld curved ship hulls and welded parts.
Description
technical field [0001] The invention belongs to the field of welding processing, and in particular relates to a method for welding a hull curved surface. Background technique [0002] Welding is a manufacturing process and technology for joining metal or other thermoplastic materials by heating, high temperature or high pressure, and is widely used in the assembly process of ships. The assembly process of the steel ship hull is roughly divided into four steps: 1. Assembling and welding each hull part to form a hull part; 2. Assembling and welding the hull parts and components into various hull sections or general sections; 3. By plane Subsections, curved surface subsections and parts and components are assembled and welded into large three-dimensional subsections or total sections; 4. On the berth, the subsections, large three-dimensional subsections and total sections are assembled into the entire hull. [0003] At present, the commonly used hull welding methods are manual...
