What is backhand welding in GTAW?

Backhand welding in Gas Tungsten Arc Welding (GTAW) refers to the technique where the welder holds the torch at an angle away from the direction of travel. This approach is beneficial for creating a more controlled and stable arc, as it allows the welder to have better visibility of the weld pool and the base metal. By angling the torch backward, the operator can also more effectively manage heat distribution, reducing the risk of overheating the base material, which is particularly important when welding thin sections or materials prone to warping.

In this technique, the weld pool is easily manipulated, and the welder can better manage the amount of filler material that is introduced, making it an ideal method for ensuring high-quality welds with a clean finish.
