Impact test for PQR

[Chintan]

Kindly advice how many set of impact test (for each process)needs to run to qualify PQR with below details
What is code ref for pqr impact test

Base metal thick 50 mm
Process GTAW (5mm) + FCAW (20 mm) + SAW (25 mm)
Governing code asme sec 8 div 1 & asme sec 9
MDMT minus 29 deg cel

[Ramesh]

Pl check UG-84 & UCS 67  in ASME Sec 8 Div.1. 

Thanks and Regards

Hello, colleagues. 

This is also my doubt. 

UG-84 does not require impact sets for each process. quantity of sets is defined only based on base metal thickness. Am I correct? 

Are additional impact sets for each process supplementary requirement in addition to ASME requirements? 

Best regards, 

[Fernando L Neto]

Sorry.

Regarding the last edition of ASME VIII, there is specific mention to multiple processes. 

Best regards

Pl ref QW 200-4, a(1).   and  UG-84- Charphy Impact Test, (h), (5). It is clearly given for multiple welding process.

Dear,

Requirement for each welding process to Impact testing is not a Sec.8 or Sec.9 requirement of ASME Code but this will be a requirement in some Client specifications.

Please see Sec.8 requirements below snap shot.

Thanks & Regards
