6082 aluminum alloy belongs to the A lM gS i series heat-treatable and strengthened aluminum alloy. It has medium strength, good weldability and corrosion resistance. Its T6 state has high mechanical properties and is widely used in mechanical parts, commercial vehicles, and railway structures. Parts and shipbuilding, etc.
In the past ten years, due to the increasing demand for high-speed ships in the world's shipping industry, aluminum alloy ships have developed rapidly due to their light weight advantages. Aluminum alloy has a small specific gravity, corrosion resistance, and moderate mechanical properties, 6082 aluminium alloy ribbed plate Used in ships, it can increase the speed of the ship, reduce the weight of the ship, and improve the stability of the ship. It is an ideal shipbuilding material.



One of the main obstacles to the application of aluminum alloy welded structures to shipbuilding is the difficulty of controlling welding deformation. The linear expansion coefficient of aluminum alloy is large, 2.5 times that of steel, and its elastic modulus is low, only 1/3 of that of steel, and its thermal conductivity is much higher than that of steel. Therefore, the welding of 6082 aluminum alloy ribbed ship plates is prone to large deformation. The welding deformation of aluminum alloy workpieces can be divided into longitudinal deformation, transverse deformation, bending deformation, angular deformation, wave deformation, and twisting deformation. Kinds; According to the deformation form of the welded structure, it can be divided into local deformation and overall deformation. The local deformation of a welded structure refers to the deformation of a certain part of it. It mainly includes angular deformation and wave deformation. This type of deformation generally has little effect on the structure and is easy to correct.
