Aluminium TIG Rods Range
Aluminium TIG welding rods are used for welding aluminium and aluminium alloys. They are lightweight, corrosion-resistant and have excellent thermal conductivity.
Engweld stocks a range of aluminium TIG welding rods in 4043 and 5356 standards. The main difference between the two is the composition of alloy elements in them. 4043 is an aluminium alloy with a higher silicon content. It is a general-purpose alloy that is commonly used for welding aluminium alloys that are not heat-treatable. 5056 aluminium alloy contains magnesium and is used to weld heat-treatable aluminium alloys such as 5086 and 6061. It has a higher tensile strength compared to 4043.
Which is the best shielding gas for use with Aliuminium TIG welding rods
For TIG welding aluminium with rods (GTAW), the best gas from the Energas ARCAL™ range is once again ARCAL™ Prime.
While MIG and TIG are different processes, they share the same requirement for aluminium: a high-purity, completely inert atmosphere.
The Top Choice: ARCAL™ Prime
-
Composition: 99.998% Pure Argon.
-
Why it’s best for TIG: TIG welding is a precision process. ARCAL™ Prime provides the cleanest arc ignition and the most stable arc possible, which is essential when you are manually feeding a TIG rod into the puddle.
-
Surface Cleaning: When welding aluminium on AC (Alternating Current), the Argon helps create the "cathodic cleaning" action that strips the oxide layer off the metal surface, allowing the rod to flow smoothly.
For Heavy-Duty TIG (Thick Plates)
If you are TIG welding aluminium thicker than 6mm, you might find that pure Argon doesn't provide enough heat, even with your amperage turned up. In these cases, Energas provides technical mixtures containing Helium (often part of their Heliweld or specific ARCAL™ Technical line):
| Gas Type | Best Application | Benefit |
| ARCAL™ Prime | General TIG (up to 6mm) | Excellent arc control and easiest to use. |
| Argon/Helium (e.g. 50/50) | Thick plates (6mm+) | Much hotter arc; deeper penetration; faster travel speeds. |
Quick Tips for TIG Welding Aluminium:
-
Use AC Output: Ensure your TIG welder is set to AC (Alternating Current). DC is used for steel, but AC is required to break the oxide layer on aluminium.
-
Tungsten Choice: Use a Zirconiated (White) or Lanthanated (Gold/Blue) tungsten electrode for the best results with ARCAL™ Prime.
-
Flow Rate: For standard TIG rods and a #7 or #8 ceramic cup, aim for a flow rate of 15–20 CFH (approx. 7–10 L/min).
