How to Weld Aluminium with Gas?

Weld Aluminium with Gas

For many projects, aluminium is the ideal material. It’s lightweight, durable and corrosion-resistant, making it perfect for a variety of applications. But when you need to weld aluminum together, how do you do it? One of the most popular methods is gas welding. Read on to learn more about how to successfully weld aluminium with gas.



Gather All Necessary Supplies

The first step in learning how to gas weld aluminum is gathering all the necessary supplies. You will need an oxygen tank and an acetylene tank, which are typically available for rent from your local welding supply store. In addition, you will need a regulator for each tank, as well as a cutting torch and other accessories like hoses and tips that are specifically designed for use with aluminum. Finally, make sure you have all the appropriate safety equipment—welding goggles, gloves and a welder’s mask—to protect yourself from potential hazards associated with welding.

Set Up Your Equipment

Once you have all the necessary supplies gathered up, it’s time to set up your equipment. Start by connecting the oxygen and acetylene tanks to their respective regulators. Make sure the connections are tight and secure before turning on either tank valve; then, carefully open each valve one at a time until you reach the desired working pressure reading on each regulator gauge. After that, attach your hoses to both tanks and connect them to your cutting torch head; then turn on both valves again until they reach their desired working pressures, as indicated by their gauges.

Start Welding Aluminium

When everything is properly connected and turned on, it’s time to begin welding! First, adjust the tip size of your torch head so that it matches the thickness of your aluminium; then start heating up one side of your joint using a sweeping motion until it reaches its melting point (about 1120°F). Once that happens, move onto the other side of your joint using a similar sweeping motion until both sides reach their melting points; then apply the filler rod one inch away from where you’re welding as you fill in any gaps between both pieces of metal. Keep applying heat until everything melts together into one solid piece; then, let cool completely before handling or removing any excess filler rod material left behind after welding has been completed.




Gas welding is an effective way to join two pieces of aluminium together quickly and easily with minimal effort required on behalf of the welder. By following these simple steps outlined above, anyone can learn how to gas weld aluminum safely and accurately in no time! However, due to its high level of toxicity when used improperly or without proper precautionary measures taken beforehand, this method should only be attempted by experienced professionals who understand how dangerous improper use can be if not handled correctly at all times. Be sure to follow all safety guidelines when attempting this type of work in order for everyone involved in the project to stay safe throughout its entire duration!
