We have to weld some of our heater tubes.
Can somebody share the welding procedure for 0.5Cr-0.5Mo-0.25V?
Welding Procedure for 0.5Cr-0.5Mo-0.25V
Re: Welding Procedure for 0.5Cr-0.5Mo-0.25V
Pre-heat: 200-250 deg C
Filler wire: ER90SB3
Electrode: E9018B3
PWHT at 675-715 deg C
Use low heat input during welding

You must focus on low heat input while welding this material as it is susceptible to re-heat cracking.
