TIG welding requires various components, but the welding gun is the main one. It holds the tungsten electrode and directs the shielding gas. The electricity comes from a power source, which can be either AC or DC. It depends on the metal being melted. The harmless shielding gas comes from a gas tank.
Another necessary component is a foot pedal for controlling the current. It also has a cooling system for the welding gun. Different tungsten electrodes and fillers are also an essential part. A high-frequency starter can help start the arc without touching the wire to the object.
Advantages
1. Accuracy: TIG offers excellent control. Therefore, it allows for precise, high-quality welding.
2. Clean welds: TIG welding is slag-free and dust-free, and the welder only needs to clean up after welding.
3. Versatile: This method can weld almost all metals. Including thin materials and dissimilar metals.
In TIG welding, the tungsten anode is very important. This electrode does not melt or become part of the metal like in MIG welding. Instead, it is only used to create and maintain the electric spark. Tungsten's high melting point allows it to resist the heat of welding sparks.
There are many types of tungsten electrodes. They often contain small amounts of substances such as thorium or cerium. These chemicals can make the spark more stable and easier to ignite. They also extend the life of the electrode. Which electrode to use depends on factors such as the metals being fused and the amount of electricity used.
