Aws_a5_10__er5183 Welding Wire compare ER5356

Comparing AWS A5.10 ER5183 welding wire and ER5356 welding wire, there are some key differences and similarities to consider:

Similarities:

1. Composition: Both ER5183 and ER5356 are aluminum-magnesium (Al-Mg) welding wires, meaning they contain a significant amount of magnesium alloyed with aluminum. Magnesium is added to improve the strength, corrosion resistance, and weldability of the aluminum alloy.

2. Weld Appearance: After welding and anodizing, both wires produce white welds that provide good color matching with the base metal.

3. Good Corrosion Resistance: Both wires offer good corrosion resistance, making them suitable for welding aluminum alloys that require resistance to chemical attack.

Differences:

1. Magnesium Content: ER5356 typically contains a higher percentage of magnesium (around 5%) compared to ER5183, which has a magnesium content of 4.3-5.2%. The higher magnesium content in ER5356 may contribute to slightly higher strength in the welded joint.

2. Welding Applications: While both wires are suitable for welding aluminum-magnesium alloys, ER5183 is more specifically designed for welding alloys containing 3% or more magnesium. On the other hand, ER5356 is a more general-purpose wire that can be used for a wider range of aluminum alloys, including aluminum-magnesium-zinc alloys.

3. Welding Process: ER5356 is often used for TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding processes, while ER5183 is also suitable for these processes but may have more specific applications depending on the alloy being welded.

4. Weld Mechanical Properties: Due to the difference in magnesium content, the mechanical properties of welds made with ER5183 and ER5356 may vary slightly. However, both wires are designed to produce welds with good strength and ductility.

In summary, the choice between ER5183 and ER5356 welding wire depends on the specific application and alloy being welded. ER5183 is more suitable for welding alloys containing higher percentages of magnesium, while ER5356 offers a wider range of applicability for different aluminum alloys.
