Marine Grade Aluminum Welding Wire

11 tips for welding aluminum in the shipbuilding industry by frank g.

Marine grade aluminum welding wire.

Argon shielding gas is required. Marine grade aluminum plate. Armao director aluminum welding technology the lincoln electric company aluminum alloys are lightweight and corrosion resistant in marine environments making the superior material for use in the shipbuilding industry. The 5000 series comprising alu minium magnesium alloys and the 6000 series which consists of aluminium magnesium silicon alloys.

Er5356 aluminum welding wire is mainly used where higher weld strength and greater ductility is required and is compatible wth 5050 5052 5083 5154 5356 6061 and 6363 alloys. Use with dc reversed polarity. There are some misconceptions within the industry that you can successfully weld any aluminum base alloy with either 4043 or 5356 filler alloy. 5356 has greater resistance to corrosion salt water and better color match after annodizing.

Our marine grade aluminium plate alloy models are 5052 5083 5086 5154 5454 5456 5754 6061 we also supply marine grade aluminum ribbed plate marine grade aluminum tread plate honeycomb aluminum plate and foamed aluminum. It retains excellent tensile strength in the weld zone. The highest strength non heat treatable aluminum alloy in commercial use. While welding aluminum can be difficult it s a skill that can be developed with the right knowledge and practice.

It is widely used in the manufacture of aircraft fuel tanks oil pipes transportation vehicles ship sheet metal parts instruments street lamp brackets. Rivets hardware electrical enclosures etc. Why aluminum welding is difficult. Keep reading to learn all about how to weld aluminum from the different types of welding you can use to general tips for success.

Aluminum is a common type of metal used in fabrication. As a basic description we can say that 4043 is an aluminum filler alloy with 5 silicon added and that 5356 is an aluminum filler alloy with 5 magnesium added. Alcan marine t he wrought aluminium alloys rolled and extruded that are used in marine applications belong for the most part to two series. Suitable for salt water or fresh 33 000 46 000 16 elong.
