چکیده
The most desired strength value in any welding process is an excellent Ultimate Tensile Strength (UTS) of the weld in respect to the parent metal. Welding process parameters should be monitored and reviewed on a continuous basis due to the increased demand for structural and industrial materials with higher strength weld joints. The goal of this study is to look into the limitations of the investigated industrial firm's existing GMAW welding process parameters used in the welding procedure, and to propose alternative, uniquely designed, and improved process parameters to replace its existing procedure welding protocol, thereby improving weld results by achieving higher Ultimate tensile strength. The proposed process parameters were then compared to available literature, and optimization was performed using the Response Surface Method.Tensile strength was determined on GMAW welding plates of ۲۰۰mm by ۲۰mm. The RSM Analysis was used to examine the data acquired from the experimental findings, and the results show that the current, voltage, and travel speed had the most significant effect on the ultimate weld strength. Furthermore, the findings show a high link between the actual and predicted ultimate tensile strength. Maximum ultimate tensile strengths of ۴۲۵, ۴۵۰, and ۴۷۵Mpa were attained at welding voltages of ۲۸ v, currents of ۲۴۰ A, and travel speeds of ۰.۰۱۲ m/s .کلیدواژه ها
