What welding technique is described as using multiple short passes to control heat input?

• A. Fillet
• B. Cap
• C. Lap
• D. Stitch

Answer: (D)

Using multiple short passes to control heat input is stitch welding. Instead of laying a single long bead across the joint, you place several small weld segments with gaps or pauses between them. Each short pass fuses the metal locally, while the gaps let the material cool a bit before the next pass. This keeps peak temperatures lower, reduces distortion and burn-through risk on thin collision-repair sheet metal, and allows you to build up full length with better dimensional control. The other terms describe the weld’s shape or the joint arrangement rather than a technique for managing heat input, so they don’t capture this method of distributing heat with spaced, alternating welds.
