Re: [MW:35213] Re: CAN A WELDER QUALIFIED TO ASME IX ALLOWED TO WELD STRUCTURES USING AWS D1.1 PREQUALIFIED WPS

Dear Gents,

As per AWS D.1.1

Para 6.2.2.1 Previous Performance Qualification. 

Previous performance qualification tests of welders , welding operators , and tack welders that are properly documented are acceptable with the approval of the Engineer. The acceptability of performance qualification to other standards is the Engineer 's responsibility, to be exercised based upon

either the specific structure or service conditions , or both.

My opinion consult with client Welding Engineer through (Technical Query or CRM)and resolve

Dear Mr. Aneesh,

According to AWS D1.1 2020 - Part 5.1  Welders, welding operators and tack welders that use prequalified WPSs shall be qualified in conformance with Clause 6, Part C or Clause 10, Part D for tubulars.

For Aramco 12-SAMSS-007 section 7.5  Welding procedures and individual welders shall be qualified in accordance with the requirements of AWS D1.1/D1.1M, AWS D1.3, AWS D1.8/D1.8M or AWS D14.1/ D14.1M as appropriate.

If the structural items construction code is AWS D1.1 - Both WPS and Welder Qualification should be as per AWS D1.1 only.

Dear Experts

Please advise if a welder qualified in 6G position to ASME Sec IX , is allowed to Weld structures using WPS which is prequalified to AWS D.1.1

Or is it mandatory to perform separate welder qualification using AWS D.1.1 WPS to weld structures 

This is for Saudi Aramco Project

KINDLY ADVICE.

Thanks 

Aneesh
