Welding Procedure Specification- WPS 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. They are a form of agile requirements documentation. What should happen (rarely if at all) is (as in ISO 14731) the welding coordinator and the Design Engineer should agree on the acceptance criteria of the weld to do it's job, before welding commences. Unless otherwise specied, accept- Interpretation 18-12R . I'm not so sure the maximum convexity criteria from this always gets proper scrutiny with the steps required to properly evaluate. Great article Karsten, very well written and easy to follow. This report, Volume 1, documents the results of this NCIG activity in describing the visual weld acceptance criteria for structural welding at nuclear power plants (NCIG-01, Revision 2). Acceptance criteria are those stated in Table 341.3.2 for radiography under Normal Fluid Service. 11.2 The Padeye must be free from excessive gouging. This criteria is usually defined in the applicable code while in other cases may be defined by the customer. RT reports normally determines the length only, but depth is just an assumption based on the image density compared to parent material. Acceptance criteria for Linear Indication (UW - 51): 1. In an ideal world, this criteria would provide clear instructions or features to make rejection decisions of all potential discontinuities. Fillet welds Qualified by butt welds:- The throat thickness approval range is based on the deposit thickness and the plate thickness range will have to be modified to that stated above. The sum of diameters of visible porosity does not exceed 3/8" in any 1" length of weld; The sum of diameters of visible porosity does not exceed 3/4" in any 12" length of weld; Any individual porosity pore shall not have a dimension exceeding 3/32". So what makes a good inspector, a clear inspection procedure. CSA W178 specifies the competency at each level, and only in level III is the inspector "capable of interpreting specifications and codes, preparing welding inspection procedures, and implementing quality assurance and control programs related to welding operations." (3) 3/4 in. A proper work instruction provided by the CSA W178 level III inspector, would detail and provide work instructions to the Level I and II inspectors. When NDE is specified after visual inspection, additional acceptance criteria may be specified based on which NDE method is used. If we're not able to determine the depth of IP for line with class 600# or above and cat M fluid, does the weld qualify based only on the length of IP? Attendees will learn about the implementation of fracture mechanics methods, (Engineering Critical Assessment = ECA), to derive flaw acceptance criteria for pipeline girth welds.

Metengr -Thanks. One of the testing contractors states that as per ASME V it is not required to mention the defect size in the report if the discontinuity complies to the code criteria. The fillet break test is more often than not failed not as a result of poor skill by the welder, but by a welding procedure that is poorly developed. . The standards are guides and try to be clear in it's instruction. lack of root penetration for Normal and Category M fluid - Girth, Miter groove and branch connection shows B as acceptance criteria. To view or add a comment, sign in. (10 mm). (3 mm) in length are considered relevant, and are unacceptable when their lengths exceed 1/8 in. Depending on the UT technique used, the NDE inspector would refer to the following tables in evaluating inspection results. Challenges introduced with the use of ECA will be discussed and the event will be rounded off with presentations on fatigue assessment for offshore risers and future challenges for the use of ECA on pipelines. Building connections are more severe because of stress concentration in the center of the weld length and column bending. Away from the complexity of the considerations listed above, some discontinuities are simple to evaluate. This way you avoid subjectiveness and perfect being the enemy of good. In girth welds and branch conn., depth permitted is 1 mm and 0.2 t. Cumulative <38 mm in any 150 mm weld length (c) This document was uploaded by user and they confirmed that they have the permission to share (0 mm). In this article, the weld defect acceptance/rejection criteria are given for the following tests/NDT; 1.

Steve Jones Acceptance criteria is a formal list that fully narrates user requirements and all the product scenarios put into the account. Having worked and inspected to the ASME code for most of my career, I agree that W59 inspection criteria can be difficult to interpret. The illustration below shows the steps to evaluate the maximum convexity of a 3/8 inch fillet weld in using this criteria and measuring the actual throat. These weld visual inspection criteria is based on: Inspection & verify the weld size ( throat size or Leg Size or fillet weld) and dimensions. Everyone started in a parking lot somewhere. Very Interesting and informative Article (a) The surface shall be free of any visible laminaions, spalling, or cracks. Transducers shall be capable of proving resolution using 3 reflections from IIW V1 Block, as shown below: Ultrasonic acceptance criteria are described, based on size of flaw, for surface and embedded flaws. It covers fully penetrated butt welds and all fillet welds Three quality levels are given in order to permit application to a wide range of welded fabrication, designated by symbols B, C and D. different quality levels are applied to individual welded joints in the same product or component. Acceptance criteria for Ultrasonic Test (UT) 4. Although the visual inspection criteria permits no fusion type discontinuities, during RT or MT inspection specified amounts are permitted based on total length compared to weld throat size. As the purchaser of the NDE services, you may require such reporting. B31.3 does not require the reporting of compliant flaws. Acceptance Criteria for Weld Defects By Sandeep Anand / April 7, 2019 In this article, the weld defect acceptance/rejection criteria are given for the following tests/NDT; 1. So you could allow for certain discontinuities and not inspect to perfect welds all the time. Welding Defect Type: Acceptance Criteria: Crack: Not acceptable: Incomplete Fusion: Not acceptable: Incomplete penetration: Not acceptable: Slag inclusions: For material thickness (t) up to 3/8 inches (10 mm), maximum slag inclusion of 1/8-inch (3mm) is acceptable. In particular, overviews of the main standards applied for this purpose will be discussed, e.g. In some cases, judgement call shortcuts may be taken instead of using the steps described here. Close this window and log in. As per ASME B31.3 Table 341.3.2 Acceptance criteria for welds, is it important to meet all the acceptable values mentioned in the criteria. Question (2): Can lack of fusion occur at the root of a groove weld joint?Reply (2): Yes. Carry out visual inspection of welds, report on them and assess their compliance with specified acceptance criteria ; Pass the CSWIP Visual Welding Inspector examination . In evaluating weld quality, inspectors should make accept/reject decisions based on comparison of the discontinuity with the applicable acceptance criteria as shown below. Indications exceeding 1/8 in. Hi, ASME Section IX is for welding procedure specification and qualification as well for welder performance qualification, so if you are inspector and testing a welder for acceptance criteria for visual inspection you need to refer to Section IX. EN ISO 5817-2007 Quality level for imperfections This International Standard provides quality levels of imperfections in fusion-welded joints all types of steel, nickel, titanium and their alloys.
