147 2 aluminum plates are placed side by side demonstrating how to fill gaps with Super Alloy 5.
- The flux is important for several reasons: it acts as an exact temperature guide, liquifying when the base metal reaches 600 degrees and indicating the base metal is ready to braze. It also cleans the base metal through paint, oil, dirt and grease, ensures an air-tight, water-tight bond, and increases the flow of the rod.
- With this application, it’s important to keep the torch at an angle perpendicular to the joint.
- If the rod balls up, your base metal is too cold. Knock the ball off, back the rod up, and add more flux and heat until the flux liquifies, then reapply rod.
