What is the recommended path length and technique to ensure a good fillet weld on a door skin patch?

• A. Use a series of short beads with steady travel, maintain proper angle and distance to create consistent fillet along seam
• B. Weld continuously in a long bead without stopping
• C. Skip beads to save time
• D. Apply filler metal while moving in any direction

Answer: (A)

Using short beads along the seam with steady travel and the right angles and distance is the best approach because it gives you control over heat input and weld shape. In thin door skin patch work, you want to fill the seam gradually rather than dumping all heat in one long bead. Small, evenly spaced beads let you monitor and adjust fit as you go, reduce the chance of burn-through or distortion, and build a uniform fillet along the entire seam. Keeping a steady travel speed helps maintain a consistent heat input, while the correct torch/work angle and a stable arc length ensure the weld pool fuses properly to both sides and forms a uniform fillet thickness.

Long continuous beads tend to overheat the thin metal and warp or burn through; skipping beads leaves gaps that weaken the joint and can lead to uneven coverage; welding in any direction without maintaining a controlled bead pattern tends to produce irregular fillets and inconsistent penetration.
