What finishing step may be performed after plug welds?

• A. Dress the welds
• B. Repaint the area
• C. Apply sealant
• D. Grind away the weld completely

Answer: (A)

After plug welds, the finishing step focuses on getting a smooth, flush surface so the patch can be properly primed and painted. Dress the welds means removing excess weld material and feathering the weld bead into the surrounding metal. This creates a flat, even contour without high spots or ridges, which helps the filler bond well and ensures the topcoat adheres evenly. It also minimizes corrosion risk at the weld line by producing a clean seam.

While repainting the area and applying sealant are part of the overall repair process, they come after the surface has been properly prepared and the welds have been dressed. Grinding away the weld completely would undo the purpose of plug welding, weakening the repair.
