Pareto optimization of TIG welding process for joining the bell metal

The bell metal parts are joined by riveting and brazing, which are not well accepted. The industry, therefore, has a high demand for suitable joining techniques. In this study, TIG welding process was used for joining the bell metal parts. The regressions equations between the welding input parameters and weldment qualities have been obtained based on the response surface method (RSM). The regression models were solved by using multi-objective...
