Reconditioning engine parts.

摘要

A method of reconditioning an engine part, for example a piston or spindle, is described. The method comprises machining the worn surface so that it is substantially flat, placing an annular repair part adjacent the annular surface, welding the repair part to the annular surface by electron beam welding and then machining a working surface of the repair part to dimensions corresponding to that desired in the engine part. The method is particularly suitable for the reconditioning of pistons and valve spindles for marine engines.
