When adding filler metal in GTAW, what practice is NOT recommended?

• A. Move filler into the weld zone
• B. Keep filler metal at the edge of the weld pool
• C. Remove filler from weld zone to cool
• D. Maintain a steady feed rate

Answer: (C)

In Gas Tungsten Arc Welding (GTAW), maintaining proper filler metal practice is crucial for achieving high-quality welds. The choice that is not recommended—removing filler from the weld zone to cool—can disrupt the welding process and compromise the integrity of the weld. When filler metal is removed or withdrawn from the weld zone, it can lead to an inadequate bead formation and might result in potential defects, such as lack of fusion or inclusions. Proper filler addition involves maintaining a constant presence in the weld pool, contributing to the overall fusion of the base metal and ensuring that the joint is adequately filled. Keeping the filler metal at the edge of the weld pool allows for better control and adequate fusion, while a steady feed rate ensures that the right amount of material enters the weld joint consistently. By not removing the filler from the weld zone, the welder helps ensure that the molten pool remains stable and that quality weld characteristics are maintained.
