Welding wire is a metal wire welding material used as a filler metal or as a conductive material. Its raw material is aluminum alloy. Aluminum welding wire manufacturers recommend that the commonly used grades of marine aluminum welding wire are 5183 and 5356.
ER5183 aluminum welding wire is an aluminum-magnesium welding wire containing nearly 5% magnesium and a higher manganese content. It has a higher requirement for welding magnesium content, has a strong tensile strength, and has excellent resistance to seawater corrosion and low temperature performance. The weld is white after anodizing treatment, which can provide a good color match for the welded joint.
ER5356 aluminum welding wire is an aluminum alloy welding wire with high strength and corrosion resistance. It uses pure aluminum as the welding core and adds an appropriate amount of magnesium, silicon and other elements to maintain the corrosion resistance of the welding surface. It is a general-purpose aluminum-magnesium alloy welding wire with higher silicon, lower magnesium and better fluidity. 5356 aluminum-magnesium welding wire has classification society certification.

5356 5183 aluminum wire application:
5356 application: used as a universal welding material for aluminum-magnesium alloy TIG welding, MIG welding and oxy-acetylene welding, and is also widely used in the welding of aluminum-zinc-magnesium alloys and the repair welding of aluminum-magnesium castings. Such as locomotive carriages, chemical pressure vessels, bicycles, aluminum skateboards and other sports equipment, military production, shipbuilding, aviation and other industries.
5183 application: used as a filler metal for aluminum-magnesium alloy argon arc welding, and is used in locomotive carriages, chemical pressure vessels, nuclear industry, shipbuilding, refrigeration, boilers and aerospace industries.
1. Strong corrosion resistance: Aluminum alloy can effectively resist seawater corrosion and extend the life of the hull.
2. Light weight: The density of aluminum is only 1/3 of that of steel, which can reduce the weight of the hull, improve load-carrying capacity and fuel efficiency.
3. High strength: Modern aluminum alloys have excellent strength and ductility, can withstand large mechanical stress, and the strength of the welding parts is reliable.
4. Good welding performance: The melting temperature of the welding wire is moderate, there are few defects during the welding process, and the thermal conductivity is good, which is conducive to the uniform formation of the weld.
5. Excellent fatigue resistance: It can resist the periodic stress in the marine environment and adapt to repeated loads.
6. Energy saving and environmental protection: Aluminum materials are recyclable, and the processing process is more energy-saving than steel, which improves environmental protection.
7. Applicable to a variety of processes: It can be used for a variety of welding methods, such as gas shielded welding and resistance welding, to meet different needs.
