[MW:8197] heat input


 
 

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 regards
