【Abstract】 The response surface method to optimize A-TIG welding parameters wais introduced in this paper,as well as the basic principles of CCD central composite design.By selecting appropriate asterisk arm and the number of repeated trials of the center point,the number of tests were reduced as far as possible and the fitting accuracy was raised.Through a comprehensive software analysis,the optimal parameter value of response was obtained.Repetitive tests were carried out to verify its accuracy,which showed that response surface method could be a good solution to A-TIG welding process optimization.更多还原
