What happens if the angle is not maintained while welding in the horizontal position?

• A. The bead becomes perfect
• B. The puddle may sag
• C. The weld penetrates too deeply
• D. The weld cracks

Answer: (B)

In horizontal welding, gravity pulls the molten metal downward, so controlling the torch angle is essential to keep the puddle contained and the heat directed along the seam. If you don’t maintain the proper angle, the puddle can sag and flow downward, leading to a bead that runs or dips and creates a weak or uneven weld. This sagging of the puddle is a common defect in horizontal welding and explains why maintaining the angle is crucial.
