ASME B&PV Code Section IX includes Essential variables that must be included in a WPS. You will write that WPS, and from which you will develop the PQR that proves the parameters used. Section IX has sample Forms for both he WPS and the PQR that you may use. The WPS will write itself (metaphorically speaking) by applying the standard assumptions to any welding procedure. Try it and have fun.
