When a discontinuity is removed and no welding is required, how should the depression be finished?

• A. Ground to fair into the original plate with slope not steeper than 1 in 10
• B. Leave as a depression
• C. Fill with filler material
• D. Weld a patch over the area

Answer: (A)

When a discontinuity is removed and no welding is required, the surface should be finished by grinding the depression to blend smoothly with the original plate. Create a gradual, flush contour so there isn’t a sharp change in geometry. The transition should not be steeper than 1 in 10 to minimize stress concentrations and maintain a surface suitable for inspection and coating. Leaving the depression, filling with filler, or patch-welding would introduce unnecessary features or materials when no repair welding is needed.
