Dear Ahmed,
If heat input change is more than 10% of your PQR,WPS is not acceptable as per ASME Sec IX QW 409.26.

Dear all,
I have come across a WPS for LTCS (with impact test) in which maximum heat input figure is below 800 joules/mm, But the actual heat input figure in supporting PQR is above 800 j/mm. I have two questions.
1. WPS is acceptable or not.
2. Which code/ standard is referred to find out acceptable heat input limit.
Construction code is ASME B31.3; WPS qualification code is ASME SEC IX
With regardsAhmed H.
