Abstract

A design for repair casting having a repairable ultra-large single-piece casting and a replacement part. The ultra-large single-piece casting includes a main body portion, at least one predefined replaceable portion integrally cast with the main body portion, and a cut-guide delineating the predefined replaceable portion from the main body portion. The cut-guide includes a continuous channel defined on an exterior surface of the single-piece casting. The cut-guide further includes a rib extending from a channel wall on the main body portion. A damaged replaceable portion is excisable from the main-body portion by cutting through the single-piece casting along the cut-guide. The excised damaged replaceable portion may be replaced with the replacement part, which has substantially the same geometry, dimensions, and mechanical properties as an undamaged replaceable portion. The replacement part may be joined to the main body portion by mechanical means or by welding.
