The current paper forms part of a series of research activities investigating the potential to implement a novel mobile device for marine diesel engine crankshaft journal surface refurbishment using laser cladding technology. Currently the laser cladding renovation process is not yet certified and is not an approved repair method for parts with highly stressed zones such as the fillets and bearing surfaces of marine diesel engine crankshafts, due to data deficiency or the absence of a validated method to evaluate high residual stress formation. In the current work, a method is proposed based on 3D transient temperature, calculating the residual stress field in the laser cladding model. The industrial application advantages of such a method are discussed and demonstrated in a case study. Further research campaigns and actions for demonstrating the industrial suitability of this method are discussed.
