APPARATUS AND METHOD FOR REPAIR AND RENOVATION OF CRANKSHAFT JOURNAL SURFACES IN-SITU BY MEANS OF LASER CLADDING

摘要

The invention refers to manufacturing engineering, in particular to shipbuilding and ship repair. Said invention applies to internal combustion engines, such as marine diesel engines. The invention relates to an apparatus in above described fields for repair and renovation of the crankshaft journal (bearing) surfaces, by means of laser build-up (cladding). Invented apparatus and method is designed to perform journals build-up (cladding) operations directly in the engine housing, without removing the crank-shaft from the engine.
