What component in the GTAW torch is designed to hold the tungsten electrode?

• A. Electrode holder
• B. Collet
• C. Gas lens
• D. Nozzle

Answer: (B)

The component in the GTAW (Gas Tungsten Arc Welding) torch that is designed specifically to hold the tungsten electrode is known as the collet. The collet is a crucial piece because it provides a secure grip on the electrode, ensuring that it remains in place during the welding process. This stability is essential for maintaining an accurate arc and achieving high-quality welds. The tungsten electrode itself conducts the electrical current needed to create the arc, so it is vital that it is securely held in the collet for proper operation. The design of the collet allows for easy replacement of the tungsten electrode as needed, providing both versatility and efficiency in welding tasks. While other components such as the electrode holder, gas lens, and nozzle play important roles in the overall function of the GTAW torch—such as managing gas flow and directing the shielding gas to protect the weld area—none of these components are tasked with holding the tungsten electrode like the collet does.
