• Response surface methodology

A central composite rotatable experimental design (CCRD) was used to plan the experiment of laser transmission joining of thermoplastic. Response surface methodology (RSM) was employed to establish the mathematical relationships between the joining process parameters (laser power, joining velocity, clamp pressure, scanning number) and the three responses (the joint strength, joint width and joint cost) and then the optimization capabilities in design-expert software were used to carry out the multi-objective optimization of the joining process. In this paper, the models were tested for adequacy using analysis of variance, the predicted errors were calculated, the effects of joining process parameters were determined, and the optimal conditions were identified. It is demonstrated that the predicted results of the optimization are in good agreement with the experimental results, so this study provides an effective instruction to enhance the joint quality and minimize the joint cost.
