Beginner Tips for Aluminum Welding

1. Is it Hard to Weld Aluminum?

Aluminum is a metal that acts differently during the process of welding. Welding steel and welding aluminum would feel different while welding. The reason for this is because Aluminum has some distinct properties that make the metal act a bit different while it’s welded.

Aluminum has a low melting point which causes the metal to burn before it melts properly. On the other hand, Aluminum is a reactive metal which causes it to oxidize quicker than most of the other metals used in welding.

2. Does Welding Aluminum Weaken it?

The answer is yes. Welding aluminum does weaken it. Almost every metal weakens after welding over time. Compare strengths of aluminum alloy that is about to be heated with the aluminum alloy that is heated.

You will notice that the parent aluminum has a much higher strength. The general reason for such a decrease in power is because heat can affect the temper of the Aluminum.

3. Which Welding Is Better TIG Or MIG?

You can use both TIG and MIG in welding aluminum. And they both are suitable for welding in their ways. Their suitability lies only in the thickness of the material. The method TIG is used for welding aluminum only when the metal is thin.

On the other hand, MIG is preferred for welding aluminum whenever the metal is thick. You need to take the thickness into account before you choose a method.

4. What is the Best Tungsten for Welding Aluminum?

You always have to keep in mind that the tungsten electrode should be big enough to carry the welding current whenever you weld Aluminum. And the reason why pure tungsten is a preference over others that dematerialized it provides a good arc stability AC welding.

5. What is the Best MIG Welder For Aluminum?

Moreover, MIG is undoubtedly not the best welding method for Aluminum, though popularly used. GTAC, which stands for Gas Tungsten Arc Welding, is an ideal welding method for Aluminum.
