In post-weld cooldown procedures for a mold, which step is performed?

Explanation:
Post-weld cooldown work focuses on cleaning and preparing the mold’s interior so it cools and releases properly in the next cycle. Cleaning the inside with a soft bristle brush or soft cotton cloth removes welding slag, scale, and debris that can lodge in cooling channels or on sealing surfaces as the mold cools and contracts. This directly protects surface finish and mold integrity for future use. Cleaning only the exterior, tightening bolts, or calibrating the temperature controller correspond to other maintenance or setup tasks and don’t address the interior cleanliness required during cooldown.
