2. How to choose 4043 and 5356 filling rods

When welding 6XXX series aluminum or 5XXX series aluminum with less than 3% magnesium, 4043 and 5356 aluminum filler rods are both common choices. They both meet high shear strength requirements and provide excellent performance in most aluminum alloy welding applications. However, depending on the specific application requirements, they each have unique advantages in different scenarios.

4043 Aluminum Filler Rod is suitable for the following applications:

• It has excellent high temperature crack resistance when exposed to high temperature environment for a long time (above 150°F).
• Applications that wish to reduce the risk of termination and shrinkage cracking, provide more stable welds and reduce welding defects.
• Welding tasks that require high weld aesthetics can produce bright and clean weld appearance.
• Workpieces that are particularly sensitive to welding deformation can minimize the deformation problems caused by welding.

5356 Aluminum Filler Rod is suitable for the following applications:

• When welding 5XXX or 6XXX series aluminum, higher tensile strengths can be achieved for high strength requirements.
• The base material after anodizing treatment needs to have a good color match, and the weld should have excellent color consistency with the base material.
• In application scenarios that withstand dynamic loads, it provides higher ductility and toughness to ensure the reliability of the welded structure.
• In connection situations where higher shear strength is required, only one welding is required to achieve higher shear strength.

3. How to choose welding materials correctly

4. How to properly store and handle aluminum filler metal?

Proper storage and handling of aluminum filler metal is critical to ensure optimal welding results. Filler metal should be kept in a dry, clean area with an ambient temperature similar to that of the welding room. Avoid moving it directly from a cold area to a warm area, which can cause condensation on the surface and affect the quality of the weld. If the aluminum wire reel is not in use, it should be wrapped in a plastic bag or other protective cover to avoid the ingress of dust and debris. It is best to store TIG cut lengths of wire in the original box for safekeeping.

5. How to get the best welding results?

When welding aluminum or other metals, speed and weld integrity are equally important. To achieve the best welding performance, you should first understand the basic characteristics and selection criteria of filler metals. Especially for beginners, you can become familiar with the handling characteristics of aluminum filler metals by practicing and using welding scraps. If you need more help or professional advice, it is very useful to seek technical support from your local welding dealer or filler metal manufacturer.

6. When welding, what equipment should be paid attention to?

To ensure a smooth welding process, in addition to the correct selection and storage of aluminum filler metal, suitable welding equipment is also required, including:

• Spool Gun or Push-Pull Gun: Suitable for MIG welding process to ensure steady feed of aluminum filler metal.
• U-groove drive roller: prevents wire from being pinched or compressed, ensuring smooth wire feeding.
• Nylon Inlet Tube and Liner: Reduces friction and reduces debris accumulation.
• Aluminum Wire Contact Tip: Specially designed contact tip with slightly larger aperture to accommodate aluminum filler metal, ensuring smooth wire feeding and maintaining a stable arc.

These equipment can greatly improve welding efficiency and ensure good welding quality.
