3. MIG Welding Applications of Aluminum Wire

ER5356 Aluminum Welding Wire is commonly used in MIG (Metal Inert Gas) welding for aluminum. MIG welding is widely applied due to its easy operation, fast welding speed, and high-quality welds.

1. MIG Welding Overview

MIG welding uses inert gas (usually argon or helium-argon mixtures) to protect the welding area from oxidation. For aluminum, MIG welding can achieve:

• Smooth weld deposition
• Excellent appearance quality
• Good penetration and joint strength

With its high magnesium content, ER5356 Aluminum Welding Wire reduces hot cracking tendency and improves structural reliability.

2. Advantages in MIG Welding

3. Common Applications

• Shipbuilding: hull and deck welding, high salt corrosion resistance
• Automotive: body frame and lightweight parts, enhancing strength and reducing weight
• Aerospace and high-end machinery: load-bearing structural welding, ensuring safety
• Lightweight architectural structures: curtain walls and roofs, high weather resistance

4. MIG Welding Considerations

• Use appropriate inert gas protection (pure argon or helium-argon mix)
• Match wire diameter with welding current to avoid burn-through or incomplete penetration
• Control welding speed to ensure smooth and pore-free welds
• Clean aluminum surfaces before welding to remove oxide and grease

4. ER5356 Aluminum Welding Wire Specifications and Selection

Selection Principles

• Based on thickness: ≤2 mm use 0.8–0.9 mm, 2–6 mm use 1.2 mm, >6 mm use 1.6 mm
• Match welding method: MIG 0.8–1.2 mm, TIG 0.8–1.6 mm
• Balance efficiency and weld quality: thicker wires allow higher deposition rate but thin sheets may burn through

Other Considerations

• Corrosion requirements: high magnesium content ensures corrosion resistance
• Welding position: horizontal and vertical require different wire feed speeds
• Prevention of defects: clean wire and workpiece, proper shielding gas

5. Application Fields
