You can also create non-code assisted documents (for documents not using ASME Section IX and AWS D1.1) in ProWrite by turning code-assistance off. Once the base material, welding process, and welding position has been filled out, the application will narrow down the filler metals and gas selections based on what fits the process according to code. h. The second repaired location may be applied hardness test to mark sure the product welds do not except allowance hardness. Assistance for Completing ASME and AWS Welding Procedure Documents. Powered by Discourse, best viewed with JavaScript enabled, AWS D1.1 (*): Structural Welding Code - Steel, ASME VIII DIV. d. Welding procedure specification (WPS) shall be applied the same as original weld product or approval WPS by Client prior to repairing work. Topics: I cannot cover all aspects of repair … VR program requirements that must be … Some CWI’s or QC Managers at manufacturing facilities create their WPS welding documents from scratch, an endeavor that can be complicated, as well as time-consuming. MINOR DEFECTS: Irregular surface by grinding, weld defects found during welding which can immediately repair. Area of crack, planar defects or volumetric defects shall be excavated by grinding or gouging. NOTE: This is a general procedure and guideline, the demonstrated procedure may require by project specification. Preparation in stainless steel and manganese steel may, however, require a little grinding. The Production Supervisor shall arrange to perform the required repair, and shall inform the QC Inspector for inspection of the completed repair. Only crack defects may drill both end of indication to stop developing expansion to other locations. You are invited comments and advise to improve procedure. e. Two-time repair attempts are allowed for (one) defect area. Part of this compliance involves ensuring the code is met with the required PQR and WPS documents. Further, when invoking a code compliant repair without post-weld heat treatment by controlled deposition welding … The contractor is required to certify that the welding . They used both two- and three-dimensional models. QC Inspector shall identify and mark the location of the defects. This enables Welding Inspectors to process with confidence when inspecting documents that have been created with code-assistance. welding can follow without any further preparation. Article V – Standard Welding Procedure Specifications (SWPSs) o This article contains the requirements for use of Standard welding procedure specifications (SWPSS). ASME IX – B 31.3 PROCESS PIPING . The repair region could not be post-weld heat treated and therefore simulations and measurements were used to determine the effect of the repair weld. ProWrite doesn’t let you save a document if there is missing or incorrect essential variables and will tell you where to find the error. 1.1.1 Qualifications of a procedure and either or both the operator or welder under Section IX of the ASME Boiler and Pressure Vessel Code shall automatically qualify the procedure … FORM QW-482 SUGGESTED FORMAT FOR WELDING PROCEDURE SPECIFICATIONS (WPS) (See QW-200.1, Section IX, ASME … After completion of repair, the locations may be examined by PT or MT to ensure that the defects have been completely removed. It’s best practice to use industry-standard software applications with cloud-based storage for consistent document creation and searchable off-site document storage. This procedure gives instruction for repair of weld that might be found defective and to be removed before welding in fabricating of vessel, structural & piping systems. The documents are enhanced with intuitive features to make completing your forms quick and easy. To bypass the many issues brought about by creating or duplicating welding documents, fabricators can use software applications that can suggest filler, base material, and gas options that are allowed per code. MT or PT methods may also support to detect the defect. The electrode is available in 3.25, 4.0 and 5.0 mm. Weld Procedure. A Standard Welding Procedure Specification (SWPS) is a welding procedure that must meet the rules for qualification of AWS B2.1 – Specification for Welding Procedure and Performance Qualification, and be approved by the AWS B2 Committee on Procedure and Performance Qualification.All SWPSs have supporting Procedure … Furthermore, CEI has and continues to work closely with ASME and AWS to remain in compliance with the latest codes and code changes. The outcome was a repair procedure … 1 (*) : Rules for Construction of Pressure Vessel, ASME IX (*): Qualification standard for welding and brazing procedures, welders, brazers, and welding and brazing operators. The software includes all the needed welding procedure forms such PQR, PQR Test Results, WPS, WQTR, and NDT forms. g. The repair welding shall be subjected to test the same method as for the original weld product. ASME IX – B 31.1 POWER PIPING . The ProWrite application provides a way to make the creation and storage of your documents quicker, more organized, and standardized. When creating welding procedures according to the ASME Section IX or AWS D1.1 codes, do you have a quick way to cross-check that the procedures are following the applicable codes? If someone else needs access to the documents, they will need access to the computer, network files, or paper documents wherever you have them stored. CEI does not assume any liability for the documents or production of a weld. All defects shall be classified in the category of major or minor defects as follows: MAJOR DEFECTS: All cracks of weld metal, planar defects or volumetric defects except crater crack. The area of this code referring to the type of welding process that is acceptable—328.2.2—states welding procedures qualified by others may be used, provided that the following conditions are met: The welding … An excavated area shall be at least 25mm beyond each end of the crack. Welding Procedure Submittals Per AWS D.1.1 or ASME Section VIII • Welding Procedure Qualification Record (PQR) – Welding Parameters followed during weld test (actual amperage voltage and travel speed) • Welding Procedure … (including ranges, if any) under which the welding … a. Either the QC Inspector or Production Supervisor may request QA/QC Manager to give more instruction for the repair when there is any doubt. Because of the procedure… If a project requires an overhead weld, the code-assistance will only suggest filler metals suitable for overhead welding. As stated in the introduction, the repair … AWS provides prequalified welding procedures that are approved by NBIC and ASME.
