Aluminum is a common metal used in many applications because of its light weight and good corrosion resistance. When welding aluminum, it is important to choose the right process to avoid damaging the material.
The most common processes for welding aluminum are:
- Gas tungsten arc welding (GTAW)/ TIG.
- Gas metal arc welding/ MIG.
- Resistance welding.
Each process has its advantages and disadvantages that should be considered when choosing the best option for a particular application.
TIG welding is a type of welding that uses a non-consumable tungsten electrode to produce the weld. An inert shielding gas (argon or helium) protects the weld area and electrode from oxidation or other atmospheric contamination. Filler metal may be used, but it is unnecessary for the process. When using TIG welding on aluminum, reverse polarity must be employed to avoid oxide build-up on the surface of the aluminum. It can be done by giving the negative charge to the workpiece and the positive charge to the electrode.
The best tig welder for aluminum is the one that can provide you with the most consistent and reliable results. There are many factors to consider when choosing a welding machine, but if you focus on finding one specifically designed for use with aluminum, you should be able to find a great option. Pay attention to aspects like duty cycle, amperage range, and features like pulse welding capabilities before making your final decision.
