What is a potential consequence of having too much torch angle?

Having too much torch angle can lead to distorted gas coverage, which is crucial in the GTAW process. The angle at which the torch is held directly influences how the shielding gas envelops the weld area. If the angle deviates too far from the optimal position, the gas may not effectively shield the weld pool from atmospheric contaminants, resulting in oxidation or other forms of contamination. This can adversely affect the quality of the weld, leading to defects such as porosity or lack of fusion.

Optimal gas coverage is essential in protecting the weld during the solidification process, ensuring that the metal retains its integrity and mechanical properties. Thus, maintaining the correct torch angle is vital for achieving high-quality welds and preventing issues associated with inadequate gas shielding.
