Abstract
This paper presents the development and design of the laser cladding machine for marine diesel engine crankshaft in-situ repairs. The described technology and device is designed to perform crankpin journal build-up operations directly in the engine housing, without removing the crankshaft from the engine. Furthermore, this technology could be successful-ly combined with the subsequent final machining operation grinding. There is already equipment and technology in place for in-situ crankpin grinding operations. Both technological platforms can be combined to deliver the most appropriate output. For the very first time, this paper outlines the novel, in-situ concept of applying laser cladding to marine crankshafts. The principal design of the in-situ laser clad-ding machine is provided and is accompanied with a de-tailed description of the in-situ laser cladding machine construction. The proposed device and method satisfy ship-board crankshaft surface renovation needs and opens up an entirely new dimension for the industrial application of laser cladding technologies.
