Abstract

The frequency of the manufacturing and modification of automotive press dies via overlay welding has recently increased, but the welding quality depends on the operator skills and the working conditions. Therefore, this study presents a way to improve the overlay welding quality regardless of the operator skills. Three welding conditions with different pre- and post-heating treatments were tested on some specimens; the weld surface quality was analyzed by examining the cutting face. The results demonstrated the best quality of the weld surface that was heated before and after the welding.
