What are the components of a typical torch assembly in GTAW?

In Gas Tungsten Arc Welding (GTAW), a typical torch assembly is comprised of several key components that work together to facilitate the welding process. The correct choice identifies these components as the body, collet, ceramic cup, and cap.

The body of the torch houses the essential components and allows the welder to control the torch. The collet holds the tungsten electrode securely in place, ensuring accurate positioning and stability during welding. The ceramic cup, also known as a gas lens, serves to focus and direct the shielding gas around the weld area while protecting the tungsten electrode and the welding arc from contamination. The cap holds the ceramic cup in position and may also serve to protect the assembly when not in use.

These components collectively contribute to the effectiveness and precision of the GTAW process, allowing for high-quality welds. In contrast, while the other choices mention items related to welding, they do not accurately reflect the specific components that make up the torch assembly itself.
