What is the main reason to test fit panels before welding?

• A. To ensure proper alignment and fit
• B. To test paint color
• C. To measure thickness
• D. To evaluate noise

Answer: (A)

Testing fit before welding ensures panel edges and surrounding body lines line up exactly as intended. Dry-fitting allows you to check gaps, contour match, and seam locations, so the panels sit flush and align correctly once welded. If this step is skipped, welding heat can cause distortion or shifting, leading to misaligned panels and gaps that require rework. The purpose here is about alignment and fit, not paint color, thickness measurement, or noise evaluation.
