In terms of skill requirement, GTAW is considered:

GTAW, or Gas Tungsten Arc Welding, is regarded as highly demanding because it requires a significant level of skill and coordination. The process involves using a non-consumable tungsten electrode to produce the weld, which demands precise manipulation of the electrode, careful control of the heat input, and an understanding of the various materials being welded. Welders must be adept at managing the arc length, adjusting the travel speed, and maintaining a steady hand to achieve a clean, high-quality weld.

Moreover, the technique requires the welder to often create a shielding gas envelope while simultaneously feeding filler material, positioning the workpieces correctly, and sometimes working in challenging positions or environments. Mastery of these techniques is essential, which makes the learning curve steeper compared to other welding processes. This high level of skill requirement is why GTAW is considered a more advanced welding method, suitable for experienced welders who have developed their technique through practice and training.
