Regarding grinding welds in a patch panel before filler application, who is correct?

When discussing the grinding of welds in a patch panel before applying filler, it's important to recognize the best practices in collision repair. The technique of grinding welds is crucial to ensure a smooth and even surface for filler application. This helps to create a strong bond between the filler and the metal surface, allowing for better adhesion and a more durable repair.

The correct approach typically involves grinding down the welds to create a flat surface, which eliminates any irregularities that could affect the finish. This ensures that the filler material adheres properly and maintains its integrity over time, thus preventing issues such as cracking or peeling after the repair is completed.

If Technician A emphasizes the need for proper grinding techniques to facilitate the adhesion of fillers, then this statement would indeed be correct, aligning with industry standards for effective collision repair. This method emphasizes surface preparation as a key factor in achieving high-quality results in bodywork.
