How Do You Select the Best Filler Rod for Aluminum Welding?

Selecting the best filler rod for aluminum welding involves considering the aluminum alloy being welded, the welding process, and the desired properties of the final weld.

Understanding the key points is crucial for effective welding. Here are the main factors to evaluate:

1. Aluminum Alloy: The filler rod should match or be compatible with the base aluminum alloy. For instance, if welding 6061 aluminum, choose a filler rod like 6061 or 4047. This ensures proper mechanical properties and corrosion resistance.

2. Welding Process: The choice of filler rod varies based on the welding technique. For Gas Tungsten Arc Welding (GTAW), ER4047 or ER5356 rods are common choices. In contrast, for Gas Metal Arc Welding (GMAW), you might prefer ER4047 rods due to their superior fluidity.

3. Desired Weld Properties: Consider the strength and corrosion resistance needed in the final weld. For high-strength applications, ER5356 is often recommended, as it has higher tensile strength compared to other fillers. If the weld will be exposed to atmospheric conditions, you may want filler rods with better corrosion resistance, such as ER4047.

4. Filler Rod Diameter: The diameter of the filler rod impacts the heat input and deposition rate. Smaller diameter rods allow for more controlled heat input, which is beneficial for thin materials. Conversely, larger rods may be more suitable for thicker sections needing faster welding speeds.
