Karthik,

                  Thanks. presently I have one PQR P1 G1 to P1 G2, so can I use this PQR for the below

 

1) P.no 1 G1 to P1 G1

2) P.no 1 G2 to P.no 1 G2

3) P.no 1 G1 to P.no 1 G2

 

The same time I can't catch the last sentence of the QW 403.5

 

The variable does not apply when impact testing of the heat affected zone is not required

by other section.

 

Louis
