What Is Aluminum Welding Called?

Aluminum features a low melting point as well as high thermal conductivity. This means specialized welding methods are required for joining aluminum pieces together to create a robust and lasting bond. Let’s check the different types of aluminum welding, the most effective techniques for welding aluminum, and the necessary tools needed to do so.

The Common Types of Welding Aluminum

Tungsten Inert Gas (TIG) Welding

One of the most popular ways to weld aluminum is through TIG welding, which is also called Gas Tungsten Arc Welding (GTAW). It involves using a non-consumable electrode made of tungsten, as well as a filler rod and an inert gas. TIG welding can create accurate and neat welds and is suitable for delicate designs and thin aluminum sheets. It is a versatile method that yields high-quality results.

Metal Inert Gas (MIG) Welding

Another technique commonly used is MIG welding, also called Gas Metal Arc Welding (GMAW). This method involves using a welding gun to feed a continuous wire electrode as well as a shielding gas that creates the weld. MIG welding is faster than TIG welding and is suitable for thicker aluminum materials.

Flux-Cored Arc Welding (FCAW)

FCAW stands for flux-cored arc welding, which is a modified version of MIG welding. It replaces the solid wire electrode with a flux-cored wire. This technique is ideal for welding outside or in areas with high winds that could disperse the shielding gas. Although it's not as frequently used for aluminum welding, FCAW can be a viable option for specific applications.

What Is the Best Way to Weld Aluminum?

To choose the most suitable welding method for aluminum, consider the needs of the project. When high precision, control, and top-notch weld quality are required, TIG welding is often considered the best option. This technique is especially useful for thin aluminum sheets and applications that require both strength and aesthetics.

If you need to weld thicker aluminum sections or want to work at higher speeds, MIG welding is your best choice. It provides solid penetration and is less difficult to learn than TIG welding. But keep in mind that the resulting welds may not look as neat and attractive as those produced by TIG welding.

The List of Tools for Welding Aluminum

To successfully weld aluminum, several essential tools are required:

1. Welding Machine. To weld aluminum, it's essential to use TIG or MIG welding machines. These machines supply the required electrical power and controls to produce a weld.
2. Torch or Welding Gun. While working with aluminum pieces, the heat is focused, and filler material is fed into the weld zone through a TIG torch or MIG welding gun.
3. Electrode. TIG welding involves using a tungsten electrode that does not get consumed, while MIG welding requires an electrode made of wire that does get consumed. The purpose of these electrodes is to conduct the electrical current needed for the welding process.
4. Shielding Gas. Shielding gas is essential in TIG and MIG welding to prevent contamination of the weld. When welding aluminum, Argon is often used as the shielding gas.
5. Filler Material. Aluminum filler rods or wires are used for adding material to the weld and promoting bonding between the aluminum components.
6. Welding cart. A welding cart is a construction on wheels that is made specifically to hold and carry welding tools, equipment, and accessories. With its help, welders can easily move their stuff from one spot to another one in the workshop or job site.

Frequently Asked Questions

Can Aluminum Be Welded?

Yes, it is possible to weld aluminum. Nevertheless, welding aluminum requires specific equipment and techniques due to its distinctive characteristics, including high thermal conductivity and low melting point.

Is Aluminum Welding Hard?

Welding aluminum can be difficult, especially for those who are new to the process. This is because aluminum has a higher thermal conductivity and is more prone to heat distortion than other metals. But with constant training and practice, anyone can acquire the required skills to weld aluminum successfully.

How to Store Welding Tools Properly?

To ensure welding tools remain functional and have a long lifespan, store them correctly. This applies to all welding tools, including those that are used for aluminum welding. Here are some tips for proper storage.

• Make sure to clean your welding tools thoroughly and remove any dirt, debris, or leftover welding materials before storing them. Doing so will help prevent corrosion and damage to your tools.
• To prevent rust and deterioration of welding tools, it's essential to store them in a dry environment. Consider using a tool cabinet or a designated area that is protected from moisture.
• To organize your welding tools, use toolboxes, racks, or pegboards to arrange them in an orderly manner. Don't forget to label the storage compartments so that you can easily identify your tools and avoid misplacing them.
• Safeguard welding equipment, specifically fragile tools such as TIG torches or MIG welding guns, from impacts or falls. To avoid any harm, keep them in padded cases or wrap them in protective materials.
• To properly store shielding gas cylinders, ensure they are upright and securely fastened to prevent leaks or tipping. Adhere to safety guidelines for gas cylinder storage by providing proper ventilation and keeping them away from flammable materials.

Can You Stick Weld Aluminum?

It's not common to use Stick welding, or Shielded Metal Arc Welding (SMAW), for aluminum welding. Due to the extreme thermal conductivity of aluminum, this method is challenging. Stick welding requires a flux-coated electrode to create a protective shield during the welding process. But it's tough to maintain enough shielding when welding aluminum with this method, which results in inadequate outcomes. As an alternative, TIG welding or MIG welding are generally the preferred methods for aluminum welding.

Conclusion

Aluminum welding is an essential technique for joining aluminum pieces effectively. There are two common methods used: TIG welding and MIG welding. TIG welding is known for its precise and clean welds, while MIG welding is faster and better suited for thicker sections. To keep welding tools in top-notch condition, proper storage should be considered. This involves cleaning the instruments, keeping them dry, and organizing them. With the right welding tools and techniques, one can learn how to weld aluminum efficiently and create durable welds for different purposes.
