Alu Minum brazing is a pretty common practice in the construction industry, where it is heavily used in the metal joining process. Besides its industrial use, it has also been prevalent in the repair of shops, homes, or even among DIY enthusiasts, as shown in the video. To get started with aluminum brazing, you’ll need these tips:
- Choose a low-temperature solder
Truly, aluminum is a versatile metal, and joining it is often a headache. This is because aluminum has a melting point temperature of 660oC.As such, to overcome the challenge, you need a low-temperature solder. Most importantly, avoid any solder that contains lead.
- Ensure you have the appropriate influx
In this case, it’s best if you use flux-cored aluminum braze rings. Alternatively, you could go for a flux whose temperature matches the melting point of your solder. That way, it saves you from taking more time and energy to reach the flux’s higher melting point. - Control the temperature and heat.
Achieving uniformity in heat and temperature while brazing is essential. Unlike welding, brazing involves a vigorous process of heating the metal pieces to a temperature above the aluminum. This ensures there are no distortions or damage to the brazed aluminum. - Get the experience you need
Now, with this step, it’s appropriate if you mastered other brazing techniques. For instance, you could try and learn torch brazing and furnace brazing. This ensures you become flexible depending on the project requirements and available equipment.
Remember, brazing is a valuable skill and can be a lucrative venture if pursued as a career. It could open doors to various fabrication possibilities. So, with proper knowledge and practice, you can develop durable and reliable joints effective for a range of uses. Go out there and learn the skill.
