What should be listed for welding progression in a WPS form?

• A. Refers to whether the welder will be welding in a vertical up travel or a vertical down travel.
• B. The angle of the torch.
• C. The bead geometry.
• D. The welding speed.

Answer: (A)

Progression in a WPS means the order and direction in which weld passes are deposited in a given position. For a vertical weld, this is about whether you weld upward from the bottom toward the top or downward from the top toward the bottom. This choice directly influences heat input distribution, how the molten metal flows, and the resulting bead shape and distortion, so the WPS specifies it to keep welds consistent across welders and passes. The other items—torch angle, bead geometry, and welding speed—affect technique and the weld outcome, but they describe how you apply the weld or what the bead ends up looking like, not the direction in which the passes are laid down.
