Shape Optimization of Deposited Layer Produced by Combined Cladding Process

A methodology of optimizing the process of combined laser cladding with induction preheating is proposed and verified. The resultant shape of the deposited layer consisting of a series of parallel tracks should be as uniform as possible and resistant with respect to cracks of any origin. The main aim is to develop a technique (based on a simple experiment) of calibrating geometrically more complex 3-D arrangements. The task consists of a solution of a strongly nonlinear coupled electromagnetic-thermal problem (forward part) and multi-parametric optimization (backward part). The solution of the forward part uses a specific h-adaptive technique developed by authors that allows working with continuously varying geometry of the system due to added powder material.
