How to Weld Aluminum with a Torch?
Having some skill in welding helps a person greatly in various ways. You may need to repair a wide range of metals occasionally, whether you are a professional welder or a DIY lover. Among them, aluminum is a common material to work on.
However, when it comes to welding aluminum, not everyone thinks of using a torch. There are more effective tools out there for the job. But they come at a high cost. You can simply do the same welding session using propane or oxy-acetylene torch and get an excellent result.
All you need to do is understand the principles, practice, and be careful during the projects. Today, we will elaborate on the welding process of aluminum using a torch step-by-step.
Equipment Needed to Gas Weld Aluminum
Torch- Obviously, you will need a torch. Whether you want to go for a propane torch or an oxy-acetylene torch depends on your preference and availability of the gases. The nozzle of the torch is where the flame will appear. Make sure that you are getting a quality torch that can heat the metal faster.
Brazing and Welding Rod- You will need brazing and a filler rod. Remember that they are made differently for each metal type. So, choose the ones only for aluminum.
Oxygen and Acetylene Gases- If you are going for an oxy-acetylene weld, you will need these gases. They come in cylinders with hoses to connect to the torch and valves to control the gas flow.
Preparing the Aluminum
You should make sure that the aluminum is ready for the weld. Follow these steps
Lighting Up an Oxy-Acetylene Torch
To oxy-acetylene weld, you will need to light up the torch properly by setting the right gas settings. Ignore these steps if you are using a propane torch.
Now that everything is ready let’s move on to the welding part. Both oxy-acetylene and propane torch will require the same steps as below
Frequently Asked Questions
What Filler Rod Should I Use to Weld Aluminum with a Torch?
You can find specially made aluminum filler rods for this project. 1100 or 3003 are good filler rods for aluminum welding with gas torches.
How Much Heat Should I Apply for Aluminum Gas Welding?
Keep the heat within 700-1200-degree F.
It is true that the project ends as you cool the metal, but your practice should not end there. In fact, you should expect to get an imperfect result on your first few tries. It is because controlling the accurate heat supply on the weld is not easy to master quickly.
With enough practice, your welding outcome can get as excellent as using high-quality welding methods. And as the equipment is easy to come by, it is even more affordable to try repeatedly.
