Which action would help manage a heavy root pass in 1G by adjusting the welding position?

In a 1G groove weld, controlling a heavy root pass comes down to how heat and gravity shape the molten metal. Tilting the torch closer to vertical increases the vertical component of the travel, narrowing the bead and helping limit excessive buildup at the root rather than letting it spread wide. Progressing downhill uses gravity to move the molten metal toward the weld toe, helping drain excess metal away from the root area. This combination keeps the root pass more balanced and better controlled. Welding farther from the vertical (more horizontal) tends to widen the bead and encourage more metal to pool at the root, which can worsen a heavy root. Simply increasing travel speed lowers heat input but doesn’t adjust the pool shape or flow. A wider root gap also tends to require more filler and can worsen the root build-up. So this approach of a more vertical angle with downhill progression best manages a heavy root pass.
