Kelly Bingham,  ES-DE Larry Goen, CENG Contact the Welding Standards POC for upkeep, interpretation, and variance issues GWS 1-02 Welding POC and Committee  GWS   1-02 ADMINISTRATIVE   CONTROL   OF   WELDING   &   BRAZING 1.0   P URPOSE &   S COPE   A.   This procedure defines the administrative controls for the LANL Welding Program for compliance with engineering drawings and specifications, applicable codes and standards, and contract requirements.   B.   This procedure applies to all welding activities performed by LANL and subcontractors at LANL as invoked by subcontract documents, in accordance with Reference 1.  LANL  Engineering Standards Manual PD342 Chapter 13, Welding, Joining, & NDE Volume 1, General Welding Standards   Rev. 7, 10/1/09 GWS 1-02 – Administrative Control of Welding & Brazing Page 3 of 11 2.0   R EFERENCES   1.   GWS 1-01, Introduction and Scope 2.   GWS 1-03, Welding and Brazing Material Procurement and Control 3.   GWS 1-05, Welder Certification by Performance Qualification Test 4.   LANL P300, Integrated Work Management 3.0   A CRONYMS AND D EFINITIONS   Acronym / Term Description AWS-CWI American Welding Society, Certified Welding Inspector CM-CE LANL’s Construction Engineering Group in Construction Management Division Codes and Standards  National consensus standards / requirements adopted by LANL for system construction and occupancy, administered for the protection of the public, worker, and environment (e.g., health, safety, and welfare. As used herein, codes include, for example, ASME, AWS, API, and AWWA standards M&TE Measuring and test equipment  Non-Code Welding Welding that does not require compliance to a national consensus code, where based on the service and usage, failure of the weld or joint would not result in serious consequences or result in a safety hazard. The WPA in conjunction with the engineer-of-record for Programs and Projects is responsible for specifying non-code welds and has the option to specify the appropriate level of weld inspection.  Nondestructive Examination (NDE) An examination process conducted to detect internal or surface defects in materials using techniques that do not damage or destroy the item being tested. The most common types of NDE are radiography (RT), ultrasonic (UT), magnetic particle (MT), and liquid penetrant (PT) methods. Depending on the applicable code, visual examination (VT) may also require control as an NDE process. Post Weld Heat Treatment (PWHT) The process of removing or reducing residual stresses in welds using heat applied in accordance with an approved procedure. Project Work to be accomplished that includes welding. QA-IQ IQ - Institutional Quality Management Group Subcontractor A legal entity that assumes by contract, obligations for delivery of a specified scope of work (product or service). As used herein, the term includes vendor, equipment vendor, fabricator, or constructor, and their sub-tier suppliers. Welder Within the LANL Welding Program, the term Welder also applies to welding operator, brazer, and brazing operator, as appropriate to the context of use.

B.   ASME “Code-stamped” Vessels and Piping only: Welding activities within the scope of the ASME Boiler and Pressure Vessel Code (Section I; Section III Divisions 1, 2, or 3; Section IV; Section VIII Divisions 1, 2, or 3; or Section X) or National Board Inspection Code (NBIC) shall be accomplished in accordance with the appropriate Subcontractor’s ASME Quality System Manual and corresponding Certificate(s) of Authorization. C.   Use of LANL Master Specification Section 01 4455, On-Site Welding & Joining Requirements: 1.   This Section summarizes requirements for welding and joining on the LANL site as required by design or other sections of the Specification, consensus codes and standards, and/or engineering design. 2.   Guidance: Specification books in the CSI format are required for certain projects by  ESM Chapter 1 Section Z10, and use of Section 01 4455 is recommended for all projects and work packages involving welding. 5.2   Welding Procedures A.   All welding performed within the Program scope as identified in GWS 1-01 by or for LANL shall be performed using pre-qualified, qualified, or ANSI/AWS Standard Welding Procedure Specifications. The qualification of LANL welding procedures shall be in accordance with GWS 1-04, Welding Procedure Qualification Tests and Records , of this program. B.   Assignment of Welding Procedure Specifications for Safety Class, Safety Significant, ML-1, and ML-2 work activities shall be approved by an AWS Certified Welding Inspector or SME authorized by the LANL WPA.  Guidance Note: Generally, a test will be administered to determine SME qualification.  C.   For all other project or program applications the responsible Manager or designated Supervisor / Engineer shall review the applicable drawings, specifications, and materials to  be welded to ensure appropriate welding procedures specifications are available to cover the work. If necessary, a new welding procedure specification shall be requested in accordance with GWS 1-02, Preparation and Control of LANL Welding Standards , and GWS 1-04, Welding Procedure Qualification Tests and Records . The WPA shall be contacted to resolve welding procedure questions. D.   Subcontractor welding procedures shall comply with requirements of GWS 1-09, Control of Subcontracted Welding. E.   Welding Procedure Specifications (WPSs), Procedure Qualification Records (PQRs), and Welder Qualification/Certification records produced by LANL legacy organizations must be reviewed and approved by the LANL WPA. Once determined acceptable by the WPA, they need not be re-qualified for use within the LANL Welding Program.
