About Welding Aluminum with Stick Welder
Welding aluminum is the process of using a welder to create a joint between two metals. In this process, a wire or rods are heated and then used to weld two metals together using a high amount of current. The welded joint is stronger and more resistant to wear and tear than the original parts. Welding aluminum with stick welder is similar to welding steel or iron with a stick welder. However, the joint created between aluminum is much weaker than the other joints.
The reason for this is that aluminum has a very low tensile strength. Aluminum is also prone to brittleness. This means that when you weld aluminum, you create joints that are prone to snapping. You can avoid this issue by choosing a stick welder with a high amperage rating and tungsten wires.
Some Common Welders for Aluminum
Now that you know how to safely weld aluminum with stick welder, the thing that you need to know is the type of welders that you can use. There are several different types of welders that you can use to weld aluminum. The most common type of welders used to weld aluminum are known as flux cored arc welders. There are also gas shielded arc welders that you can use. Each of these welders has their own advantages. When choosing which type of welder to use, you should consider the type of aluminum that you are welding.
There are different types of aluminum that are used in varying applications. If you are welding aluminum with a stick welder, you should select a welder that has a spool. The spool enables you to change the type of wire that is connected to the welder for the best welding experience.

Aluminum electrode: You will need an aluminum electrode to weld aluminum. The electrode must be clean and free of any impurities.
Tungsten electrode: A tungsten electrode is needed to sharpen the aluminum electrode. It is used to create a sharp point on the aluminum electrode.
Argon gas: Argon gas is needed to shield the weld from the atmosphere. Argon gas is a non-reactive gas that is used to prevent oxidation of the weld.
Welding helmet: A welding helmet is essential to protect your eyes from the intense light produced during welding.
Welding gloves: Welding gloves are essential to protect your hands from the heat produced during welding.
Welding apron: A welding apron is recommended to protect your clothing from sparks and heat.
Wire brush: A wire brush is needed to clean the aluminum before welding.
Clamps: Clamps are needed to hold the aluminum in place while welding.
Chipping hammer: A chipping hammer is needed to remove the slag that forms during welding.
By having these essential equipment, you can weld aluminum with a stick welder effectively.
How to Weld Aluminum with Stick Welder
Welding aluminum with stick welder can be challenging as the process requires a high amount of heat and a specific type of electrode. It’s recommended to use an AC/DC stick welder that can switch between AC and DC current. Additionally, a high-frequency unit can help start the arc on aluminum. Ensure that the aluminum surface is clean and free of any oxide layer before welding. Use 1/8th inch 4043 aluminum electrodes and set the machine to the recommended amperage. Use a whipping motion to maintain the arc and create a fusion between the aluminum pieces.
It’s important to note that stick welding aluminum is not as common as other welding methods, and it may not produce the same quality of weld as other processes like TIG welding. It can be a useful technique for those who do not have access to other welding equipment or need to make an emergency repair.
To get started with stick welding aluminum, follow these steps:
- Clean the aluminum surface thoroughly with a wire brush and degreaser to remove any dirt, oil, or oxide layer.
- Use a high frequency unit to start the arc on aluminum. This will help to establish a stable arc and prevent problems like sticking.
- Set your machine to the recommended amperage for the size of the electrode you are using. Usually, 1/8th inch 4043 aluminum electrodes are ideal for stick welding aluminum.
- Hold the electrode at a 10-15 degree angle to the joint and use a whipping motion to maintain the arc. This motion will help to create a fusion between the aluminum pieces.
- Weld in short runs, moving from one end of the joint to the other. Allow the weld to cool before continuing to the next section.
- Use a stainless steel brush to clean up the weld after it has cooled.
With practice and patience, you can achieve a strong and reliable weld when stick welding aluminum. However, it’s important to remember that this technique is not suitable for all applications and may not produce the same quality of weld as other methods like TIG welding.
