Abstract: The fabrication of super alloy elements, followed by welding, is the subject of this study, which has a significant impact on the manufacturing business. Furthermore, numerous materials are used, one of which is P91. Many researchers have chosen P91 steel over the last two decades because of the key advantages it has, including its utilization in power plants, where it is common to have pipes that must sustain steam at temperatures between 570 and 600 °C and pressures between 170 and 230 bar. For most conventional steels, these operating conditions are important, needing higher high-temperature mechanical strength and strong creep resistance.
