Abstract: In this paper, an attempt is made to set the optimal laser transmission welding parameters to attain a desired weld seam with maximum joint strength. The earlier developed mathematical models are used to optimise the welding process. Design-expert software is used to optimise the process parameters, taking into account two proposed optimisation criteria. Numerical and graphical optimisation techniques are applied. The result of numerical optimisation predicts two pareto-optimal solution sets according to the planned optimisation criteria; whereas, graphical optimisation result produces overlay contour plots, which allow quick visual inspection of the area of desirable response values.
