aluminum steel transition joints used in shipbulding
In the modern shipbuilding industry, especially in the construction of high-speed ships, in order to achieve lighter weight and improve ship speed, aluminum alloy structures with lower density are often used. Due to the considerations of strength, carrying capacity, cost, and durability, the main hull is usually a steel structure. The aluminum alloy is used only for the superstructure to reduce weight and lower the center of gravity, thereby improving the performance of the hull. Therefore, the high-strength connection between aluminum and steel between the upper and lower layers of the hull relates to the cruising performance and service life of the entire ship.

Our aluminum steel transition joints allow direct welding between aluminum alloy components and steel structures. They are widely used in shipbuilding, high-speed rail trains, and automotive industries, and are mainly used to construct the upper structure of hulls or bodywork, thereby achieving The purpose of reducing weight and improving transportation capacity.

aluminum steel transition joints

Compared with traditional rivets or bolts, the use of aluminum steel transition joints can be directly welded to achieve the connection between the aluminum alloy and steel structure, without drilling and other work. And due to the metallurgical bonding interface, aluminum steel transition joints have high strength, anti-electrochemical corrosion and other characteristics, and further improve the product's reliability and longevity.
