Hi folks,
I have an existing PQR performed with alloy 800 plate and welding consumables. All of the mechanical tests were performed at room temperature.
I now have a new project that I am considering using this PQR and deriving a wps from. However, the design temperature of the new project is just under the allowable in the code (ASME). Do I need to consider performing a new weld test with elevated temperatures for tensile tests? I am not sure if there is anything in the ASME code which would direct me to do new or additional tests at elevated temperatures to prove out the mechanicals for use in a unit with an operating temp of 500 deh c.
Any assistance would be greatly appreciated.
