HARTFORD STEAM BOILER GLOBAL STANDARDS.Duties: Responsible of Pressure Vessels, Heat Exchangers, (Items and Parts), Storage Tanks and Structural Steel shop and field inspections and testing performance during construction and assembly.2, and "S" Stamp, Certification (2004) for Shop and Field Construction and Assembly of Power Boilers.Team Leader and Responsible of company's ASME Code, "U2" Stamp, Certification (2004) for Shop and Field Construction and Assembly of Pressure Vessels and Heat Exchangers, according to the Section VIII, Div.1, and the NBIC Recertification (2004), "R" Stamp, for Shop and Field Repairs and Alterations of Pressure Retaining Items.
Additionally, I have designed and implemented Quality Management Systems (QMS) for several organizations, according to the ASME Code, ISO 9000 Standards and the API Q1 Standards, participating always as an active team leader and active member, having the opportunity to work among different scenarios, always seeking a high performance and safety operation. Pressure Retaining Items, Repairs and Alterations according to the ASME Code and the National Board Inspection Code (Stamp: "R"). 2 (Stamps: "U" and "U2") and Section I (Stamp: "S") Storage Tanks designed according to the API Standards, Piping and Structural Steel designed according to the ASME Code and AWS Standards. (3 mm) shall be permitted along the approximate weld interface.More than Thirteen (13) years experience in the oil & gas industry and mechanical construction industry in the areas of Quality Assurance and Quality Control Management, Design, Construction, NDE, Testing and Inspections of Pressure Vessels, Heat Exchangers (items and Parts), and Power Boilers, designed according to the ASME Boiler and Pressure Vessels Code, Section VIII, Div. (1.5 mm), measured in any direction, shall be permitted in the cladding, and no open discontinuity exceeding 1/8 in. Open discontinuities occurring on the corners of the specimen during testing shall not be considered unless there is definite evidence that they result from lack of fusion, slag inclusions, or other internal discontinuities.įor corrosion‐resistant weld overlay cladding, no open discontinuity exceeding 1/16 in. The guided‐bend specimens shall have no open discontinuity in the weld or heat‐affected zone exceeding 1/8 inch (3 mm), measured in any direction on the convex surface of the specimen after bending. The weld and heat‐affected zone of a transverse weld bend specimen shall be completely within the bent portion of the specimen after testing. 4 bend tests (2 transverse and 2 longitudinal ) or (4 Transverse).Chemical Analysis at a depth of overlay thickness for which WPS to be qualified, refer Figure 2 below.Relevant indications: indications with major dimensions greater than 1/16 in. Liquid Penetrant Test as per ASME BPVC Section V article 6,Īcceptance Criteria for Liquid Penetrant Testing.Tests as per standard (ASME BPVC Section IX) The dimensions of the test specimen is as below and in Figure 1.ġ50mm x 150mm x minimum thickness of production, overlay for a width of 38mm minimum. Plate: Plate sample shall have thickness = minimum thickness of production Preparation of Test Sample:Ī test sample of same grade, or same P.Number or similar chemical composition is selected for test coupon. Tube sheet: tubesheet sample should have a thickness = minimum thickness of production or 50mm (2” ) whichever is lesses. After successful completion of tests, prepeare the Welder performance Record.Perform the NDT 7 Mechanical test on the welded coupons as per the requirements of ASME Section IX.For additional welders, ask them to perform welding as per qualified WPS.For the welder performed the PQR qualification test prepare the Welder certificate.Prepare the Welding Procedure Specification ( WPS ) with ranges qualified for production.Prepare the Procedure qualification record ( PQR ).Carry out the testings on the weld overlay as mentioned in the standard, Non Destructive Testing ( NDT ) & Mechanical Testing.Weld the overlay / cladding over the test sample with appropriate filler metal.Select the sample size (thickness of base metal).Step by step procedure for WPS preparation: The reference standard selected for the purpose of qualification of cladding procedure and welder qualification is ASME Boiler and Pressure Vessel Code (BPVC) section IX.
This document details, how to qualify a welding procedure specification-wps for weld metal overlay / cladding / surfacing, for both corrosion resistance overlay and wear resistance overlay welding.
