Processing parameter optimization of fiber laser beam welding using an ensemble of metamodels and MOABC
文献摘要：
In fiber laser beam welding(LBW),the selection of optimal processing parameters is challenging and plays a key role in improving the bead geometry and welding quality.This study proposes a multi-objective optimization framework by combining an ensemble of metamodels(EMs)with the multi-objective artificial bee colony algorithm(MOABC)to identify the optimal welding parameters.An inverse proportional weighting method that considers the leave-one-out prediction error is presented to construct EM,which incorporates the competitive strengths of three metamodels.EM constructs the correlation between processing parameters(laser power,welding speed,and distance defocus)and bead geometries(bead width,depth of penetration,neck width,and neck depth)with average errors of 10.95％,7.04％,7.63％,and 8.62％,respectively.On the basis of EM,MOABC is employed to approximate the Pareto front,and verification experiments show that the relative errors are less than 14.67％.Furthermore,the main effect and the interaction effect of processing parameters on bead geometries are studied.Results demonstrate that the proposed EM-MOABC is effective in guiding actual fiber LBW applications.
