A weld repair method that involves thin sheets of corrosion-resistant material welded to a corroded surface is ___.

• A. Sheet lining
• B. Cladding
• C. Overlay
• D. Lamination

Answer: (A)

The key idea is using thin sheets of corrosion-resistant material installed as an inner lining by welding to the existing surface. This method, called sheet lining, directly describes applying those thin sheets to the corroded surface to restore corrosion resistance. Cladding refers to bonding a protective layer to a base metal, often as a continuous layer that forms a new outer surface and can be thicker; overlay is a weld deposit added on top of the worn area to regain thickness, not a separate sheet; lamination implies stacking multiple layers to form a composite, which isn’t the typical repair approach here. Therefore, sheet lining best fits the scenario of welding thin sheets to the surface to create a corrosion-resistant lining.
