## How Does Aluminum TIG welding machine Work?
1. How does the aluminum TIG welding machine produce heat?
2. What is the role of the tungsten electrode in TIG welding?
3. How is the filler metal added in aluminum TIG welding?
Aluminum TIG welding machines work by using a tungsten electrode to create an electric arc that generates heat to melt the aluminum pieces being joined together. .
The tungsten electrode, which is non-consumable, is held in a torch and connected to a power source. When the welder presses the foot pedal, an electric current flows through the electrode, creating an arc between the electrode and the aluminum workpieces. This arc produces intense heat, melting the aluminum and allowing the pieces to fuse together.
In TIG welding, the filler metal is added manually by the welder. The filler rod, made of the same material as the workpieces, is held in the other hand of the welder. As the aluminum pieces melt, the welder introduces the filler rod into the molten pool to add material and reinforce the weld joint.
Overall, aluminum TIG welding machines work by using a tungsten electrode to create a controlled electric arc that produces heat to melt the aluminum workpieces. The addition of filler metal helps to create a strong and durable weld joint between the aluminum pieces.
