I have a WPS for SMAW+SAW process Material SA 516 GR.60/70 with PWHT requirements of 631°C temperature and 450 minutes holding time.Now, I have a new project with PWHT requirements of 600±25°C temperature and 3 hours holding time.
Can I use the existing WPS for this new project? What is the acceptable deviation (±) for PWHT requirements?
Looking forward to your guidance.
Best regards,
