Which technique helps control puddle width during TIG welding?

• A. Large, rapid torch moves
• B. Small, steady movements
• C. Stopping and starting
• D. Pushing deeply into puddle

Answer: (B)

Controlling puddle width in TIG welding comes from managing heat input with steady, deliberate motion. Small, steady torch movements apply heat evenly along the seam, keeping the puddle compact and the bead shape predictable. Large, rapid movements disrupt heat balance and cause the puddle to widen unpredictably. Stopping and starting interrupts heat distribution, creating irregularities in the puddle and bead. Pushing deeply into the puddle increases penetration and heat in a way that tends to widen the puddle and can lead to burn-through or poor geometry. So using small, steady movements helps maintain a consistent puddle width and better overall weld quality.
