Marine Aluminum Tubing and Filler Rod
For marine welding, aluminum welding wire is used as a filler material or as conductive wire at the same time such as gas shielded welding wire, etc. The commonly used aluminum welding wire on ships are 5356 and 5183 aluminum-magnesium welding wire. 5356 filler rod is too common and often used in various industries.
5356 aluminum welding wire, as a general-purpose welding material widely used in the field of aluminum alloy welding, its 5% magnesium alloy composition makes it particularly suitable for welding a variety of aluminum alloys, especially those that require higher strength and good corrosion resistance. Specifically, 5356 aluminum welding wire is most commonly used for welding 5-series and 6-series aluminum alloys, such as 5052, 5083, 6061, 6063,etc.
5183 welding wire is particularly widely used in the welding structures of marine vessels such as ships, catamarans, and high-speed ships. The main reason for the wide application of this alloy is that it has a combination of high strength, high corrosion resistance, high bending ability and high weldability. The weld strength of AA5183 alloy can be improved by increasing the Mg content in the alloy, and the loss of ductility is not large.
Marine aluminum alloy profiles are mainly used for ship structures and accessories. Common profiles include angle steel, square tubes, round tubes, etc. There are many alloy grades for 6 series aluminum profiles, and the most commonly used alloy is 6082 alloy.
6082 marine aluminum tubing has high mechanical strength and excellent corrosion resistance, and is particularly suitable for the manufacture of structural parts in the fields of shipbuilding, bridge engineering, and transportation vehicles. Its light weight and high strength make it an ideal choice to replace traditional steel materials.
There are four main tempers of 6082 aluminum tube: O, T4, T6, and T651. They have good anodic reaction performance. For example, the air conditioning pipes in our daily life are made of 6082 aluminum tube. In particular, the O and T4 temper of 6082 aluminum tubes are mainly used in bending and forming occasions.
