WPS for A537 CL2?

[amin1222]

Hi everyone
I'm searching for a proper WPS for welding a pressure vessel by 'a537 cl2' including preheat, maximum interpass temperature and pwht condition. The thickness of base plate is 48mm and I've suggested E8018-C3 for filler metal.Can somebody help me?

ask the manufacturer of the welding rods like ador or lincon etc. for appropriate filler rod selection and for making the WPS go to ASME Boiler & Pressure Vessel Code Section IX.
