At what angle should a GTAW torch typically be held?

In Gas Tungsten Arc Welding (GTAW), the angle of the torch is crucial for achieving proper penetration and control of the molten puddle. Holding the torch at an angle of 15 to 20 degrees from vertical is the typical practice because this positioning allows for a balance between visibility and control over the weld.

This slight angle helps in directing the arc to where it is needed, while also enabling the welder to create a stable and consistent puddle. The 15 to 20-degree angle provides accessibility to the weld zone without compromising the control needed for precise welds. In addition to improving visibility of the weld pool, this angle helps in directing the heat towards the workpiece effectively, facilitating better fusion.

In contrast, a torch held at a greater angle might lead to improper puddle formation or excessive heat input in one area, which can negatively affect the integrity of the weld. Therefore, the angle of 15 to 20 degrees from vertical is widely taught and utilized for optimal results in GTAW processes.
