AWS Class ER5356 Welding Wire – Composition, Properties, and Uses

AWS Class ER5356

The process of selecting the right welding electrode depends on several factors, including the material of the welding piece, the welding technique, the welding environment, and the desired properties of the end product. And when it comes to welding aluminium, AWS Class ER5356 is one of the most popular welding electrodes professionals use. In this blog post, we will discuss everything there is to know about AWS class ER5356, its composition, mechanical and physical properties, uses, corrosion resistance, and heat treatment.

What is AWS Class ER5356?

AWS Class ER5356 welding wire is a bare, all-position aluminium alloy welding wire used for MIG and TIG welding applications. This high-strength wire can weld 5XXX series aluminium alloys and structures containing castings and wrought materials. It offers superior corrosion resistance in marine environments, making it ideal for building or repairing boats, ships and other watercraft. In addition to its strength, its strontium content provides excellent arc stability while producing low spatter during welding.

ER5356 Welding Wire Composition

AWS Class ER5356 welding electrode is an aluminium magnesium welding wire with 5% magnesium and 0.8% manganese content. Its chemical composition makes it ideal for welding aluminium alloys 5083, 5086, 5154, 5454, and 5456. ER5356 is suitable for both MIG and TIG welding processes.

ER5356 Coated Wire Uses

AWS Class ER5356 filler metal is commonly used in welding aluminium sheets and plates that require high strength and excellent flexibility. ER5356 is also used for welding aluminium alloys in the marine, aerospace, and transportation industries. Other applications include bicycle frames, race car parts, and automobile components.

ER5356 Welding Wire Corrosion Resistance

ER5356 is highly corrosion-resistant and can withstand exposure to saltwater, atmospheric corrosion, and most chemicals. This wire’s corrosion resistance is important for marine applications, where the welded joint must withstand exposure to water and salt.

ER5356 Coated Wire Heat Treatment

AWS Class ER5356 is a non-heat-treatable alloy which can’t be hardened via heat treatment. However, the welded joints can be annealed to restore the alloy’s original strength and flexibility. Annealing is a heat treatment process that involves heating the welded joint to a specific temperature and cooling it slowly.

Conclusion:

AWS Class ER5356 is an excellent choice for welding aluminium alloys requiring high strength, flexibility, and corrosion resistance. Its unique chemical composition, excellent mechanical and physical properties, and high corrosion resistance make it ideal for the marine, aerospace, and transportation industries. We hope this comprehensive guide has given you a better understanding of AWS Class ER5356 and how it can be used in your welding projects.
