What describes forehand welding in GTAW?

Forehand welding in Gas Tungsten Arc Welding (GTAW) is characterized by the technique of angling the torch towards the direction of travel. This approach allows the welder to maintain better control over the weld pool and provides a steady heat application to the joint being welded. It is particularly beneficial when working with materials that require a keen focus on the heat input, such as thin plates, as it encourages smooth bead formation and reduces the risk of burn-through.

This method ensures that the welder effectively directs the shielding gas and heat to the area in front of the torch, promoting optimal fusion and penetration. By having the torch angled towards the journey of the weld, the operator can manipulate the puddle more precisely, which is essential for achieving high-quality welds in sensitive applications or with challenging materials. The increased visibility of the weld pool also aids in better decision-making during the welding process.
