Determining of the laser heat flux for three-dimensional conduction model by the sequential method

When performing a laser processing, one of the parameters to consider is the laser heat flux. This is a very important parameter of the processing. It is difficult to directly and correctly measure this parameter during the processing. Therefore, to estimate this parameter, a solution has been implemented. In this study, the Newton–Raphson method has been calibrated as an operational algorithm to evaluate the laser heat flux value accurately in the 3-D conduction model. To confirm the effectiveness of the presented method, the paper has given two specific applications. It is obtained that the sequential method is a reasonable, correct, and powerful method to determine the inversely laser heat flux in the three-dimensional conduction model.
