| Abstract: | An experimental investigation on transmission welding of polycarbonate( PC) filled with and without black carbon has been carried out. Furthermore,correlations between the laser transmission welding parameters and output variables are developed by applying response surface methodology( RSM). The process parameters of the model include laser power,welding speed,clamping force and cooling time,the output parameters of the model include maximum tensile load. The design expert v8. 05 b establishes the design matrix and obtains the regression equation,in order to analyze the influence of the process parameters on the tensile load. The analysis-of-variance( ANOVA) method is used to check the models' adequacy.Results reveal that the measured and calculated results are in good agreement. |
