If you have a broken piece of cast aluminum outdoor furniture, you may be tempted to throw it away. Cast aluminum is notoriously difficult to weld. Unlike other metals, aluminum does not turn red as it heats, so it's hard to monitor the temperature as you're welding. However, if you have the right tools, it can be done. Alumaloy welding rods work well with cast aluminum. All you need to do the job is the rods and a handheld propane torch. Does this Spark an idea?
Instructions
1. Thoroughly clean the area you want to weld. It must be totally free of oil or any other dirt.
2. Preheat the Alumaloy rod using the flame of the handheld propane torch.
3. As the Alumaloy starts to melt, press the rod into the surface of the aluminum.
4. Continue to heat the aluminum while dipping the rod in and out of the molten puddle until you have built up the desired amount of Alumaloy.
5. Let the metal cool completely before touching.
