Laser cladding is globally known as the most advanced surface restoration technique, with unique advantages over others. These advantages make it the perfect solution for reliable restoration of main and crankpin journals of marine crankshafts. Since 2011 we have repeatedly restored marine crankshafts of various types, successfully. One of the cases we encountered was that of a customer whose auxiliary engine an MAN B&W 5L23/30, suffered from main and crankpin journals damage. As spare crankshaft had long delivery time and undersize bearings was hard to get on time, machining of all journals to undersize, was not a solution. Therefore we restored all journals on our laser cladding cell, followed by machining and grinding to final and standard dimensions. The whole process end up in lower cost, compare with the previous two options, and reduced down time.
