[MW:5269] PQR with double cycle PWHT fo overlap long seam

By Materials & Welding
Hi Members,
 
A vessel is done PWHT seperately in two sections. After that the closing seam to be done the PWHT locally.
At local PWHT area a small portion of long seam  (app. 150mm) is subject to PWHT second time due to the overlap of heating element.
 
Job is with impct test requirement.
 
In this case is it required to support a PQR with double cycle PWHT for the long seam?.
Is there any code exemption in this case?

Thanks & Regards
Muhammed Ibrahim PK
