"TIG welding sets" refer to Tungsten Inert Gas (TIG) welding equipment, commonly known as Gas Tungsten Arc Welding (GTAW) equipment. TIG welding is a welding process that uses a non-consumable tungsten electrode to create a high-temperature arc to join metals. The arc is shielded from the surrounding atmosphere by an inert gas, typically argon or helium, hence the name "inert gas welding."
Usage of TIG Welding Sets:
- Joining Metals: The primary purpose of TIG welding sets is to join metals together through a precise and controlled welding process.
- High-Quality Welds: TIG welding is known for producing high-quality welds with excellent strength and aesthetic appearance.
- Versatile Application: TIG welding sets are used in a wide range of industries, including aerospace, automotive, fabrication, and more.
How it Works:
- Power Source: The TIG welding set includes a power source that supplies the necessary electrical current for the welding process.
- Non-Consumable Electrode: Tungsten is used as the non-consumable electrode in TIG welding, which means it does not melt during the process.
- Inert Gas Shielding: An inert gas, such as argon or helium, is fed through the welding torch to shield the welding area from atmospheric contamination, ensuring a clean weld.
- Welding Torch: The welding torch holds the tungsten electrode and guides the welding arc to the joint.
- Filler Metal (Optional): If needed, a separate filler metal can be added manually to the joint to enhance the weld strength and fill any gaps.
- Welding Process: The welder strikes an arc between the tungsten electrode and the workpiece, generating the heat required for melting the metals at the joint.
- Weld Pool Control: The welder controls the heat input and weld pool formation using a foot pedal or hand control, allowing for precise control over the welding process.
- Advancement and Cooling: As the welding torch advances along the joint, the molten metal cools and solidifies, creating a strong, fused joint.
- Post-Weld Cleaning: After welding, the welded joint may undergo post-weld cleaning to remove any residual oxides and ensure the highest quality of the weld.
