What is the recommended torch angle for GTAW?

The recommended torch angle for Gas Tungsten Arc Welding (GTAW) is typically between 0 degrees to 15 degrees from vertical, which allows for optimal control of the arc and shielding gas coverage. At this angle, the welder can direct the arc precisely where it is needed, ensuring that the heat is concentrated on the joint being welded. This close placement also helps maintain an effective shielding gas envelope, minimizing contamination and oxidation of the weld pool.

Using a torch angle in this range enhances stability and provides better control over the molten pool, which is critical for producing high-quality welds. Additionally, maintaining a shallow angle helps the welder avoid excessive filler rod consumption and potential spatter.

In contrast, larger angles, such as those proposed in the other options, can lead to less control over the arc, increased risk of defects in the weld, and inefficient use of shielding gas, all of which can compromise the integrity of the weld. Thus, sticking to the recommended angle promotes a more effective and cleaner welding process.
