A ______ weld is made by starting and stopping briefly between welds.

A ______ weld is made by starting and stopping briefly between welds.

• A. A walk weld
• B. A random weld
• C. Stitch
• D. Flare weld

Answer: (C)

A stitch weld is formed by placing short weld segments along a seam with brief pauses between them. This pattern starts and stops between welds, which is exactly how heat input is kept in check. By breaking a long weld into multiple small spots, you limit heat buildup, reduce distortion and burn-through on thinner materials, and still achieve the needed joint strength when the welds are placed correctly along the seam. The other terms describe different welding patterns or joint types that don’t match the idea of intermittent, separately placed welds: a walk weld implies a continuous travel bead, a random weld lacks a defined, repeating pattern, and a flare weld refers to a specific joint geometry not about intermittent spots along a seam.
