Diff. between WPS of SEC-IX and AWS D1.1

[Ramesh Barot]

Dear Experts,

 

Greetings,

 

I have one basic question about WPS.

 

Please share your valuable opinions with me that Difference between qualification of WPS with AWS D1.1 and ASME -IX.

 

Can we use the WPS qualified with SEC-IX for steel structure and vise versa?

 

 

Thanks,
With Best Regards,
Ramesh Barot

ASME- Scen. IX-- exclusively for pressure vesel
AWS D1.! - Meant for Structural welding code
No, We can not use WPS qualified with SEC-IX for steel structure and
vise

Thanks

Hi, Pls.find below the extraction of AWS and ASME Sec.IX.According to that,Sec.IX WPS may not be used for AWS. But AWS SWPS can be used for ASME as per QW-100.1. AWS - 4.1.1.2 WPS Qualification to Other Standards. The acceptability of qualification to other standards is the Engineer’s responsibility, to be exercised based upon the specific structure, or service conditions, or both. AWS B2.1.XXX-XX Series on Standard Welding Procedure Specifications may, in this manner, be accepted for use in this code.   ASME-Sec-IX QW-100.1 A Welding Procedure Specification (WPS) is a written document that provides direction to the welder or welding operator for making production welds in accordance with Code requirements. Any WPSs used by a manufacturer or contractor that will have responsible operational control of production welding shall be a WPS that has been qualified by that manufacturer or contractor in accordance with Article II, or it shall be an AWS Standard Welding Procedure Specification (SWPS) listed in Appendix E and adopted by that manufacturer or contractor in accordance with Article V. Both WPSs and SWPSs specify the conditions (including ranges, if any) under which welding must be performed. These conditions include the base metals that are permitted, the filler metals that must be used (if any), preheat and postweld heat treatment requirements, etc. Such conditions are referred to in this Section as welding “variables.” Thanks & Regards, (Karthik) Karthikeyan.S QA/QC Manager Getabec Energy Co.,Ltd. 379,Moo6,Soi8,Nikhomphatana, Rayong-21180, Thailand.

I feel you can use the WPS qualified with Sec.IX for the structural parts of the pressure vessels/piping provided the AWS D1.1 is not used for design of the structure. I remember the design code (Sec.VIII/ASME B31.3) gives such permission.

 

But if the structure is designed as per AWS D1.1 (like, process platform or bridges, etc. where the provisions of D1.1 are used  for designing, then you cannot use the WPSqualified by ASME Sec. IX.

 

The codes are far different in their qualification strategy.

 

I hope this may be useful,

However, look at the PQR parameters and see if it can be re-presented in the new required format. sometimes it can be re-used to suit the other code requirements and a new WPS. --- On Fri, 10/6/11, Prasad Joshi <sur...@gmail.com> wrote:

Dear Ramesh,

WPSs qualified to ASME IX code is allowed for AWS D1.1 welding with consent of buyer as stated in AWS D1.1 - 2010 clause 4.2.1.2.

Moreover, the structure designed as per AWS will not be subjected to similar type of integrity tests as per ASME Sec VIII/B31.3/31.1 because ASME is for pressure vessels, boilers etc.

Hope this will help.

Referencing codes shall be used in conjunction with code of construction.

It all depends on Code of Construction. Some codes permit use of both codes/standards.

AWS D1.1 is more stringent than ASME sec 9 regarding position and so on . Ref 4.1.1.2

Dear Ramesh:

As Shashank said, you can use it if it reflects you actual welding conditions and PQR includes required tests and results. But this is always the engineer's decision (it's better to receive client's approval). If there are reasonable justifications, go ahead and use it.
