DYE PENETRANT INSPECTION - AWS D1.1. Acceptance criteria is dependent on service condition. Refer to the relevant project NDT Supervisor or Area NDT Manager. DYE PENETRANT INSPECTION - ANNEX - II. ULTRAVIOLET LIGHT INTENSITY VERIFICATION. May 13, 2014 Visual inspection of welds in all steel may begin immediately after the complete welds have cooled to ambient temperature. Acceptance criteria for ASTM A 514, ASTM A 514 and A 709 Grade 100 and 100 W steels shall be based on visual inspection performed not less than 48hours after completion of welds. Even though the overall appearance of the welds may meet the visual acceptance criteria, it cannot be assumed that they meet the minimum quality requirements of the code or minimum design requirements specified on the approved drawings. AWS Inspection Requirements The following weld inspection requirements are from AWS D1.1 Section 6 and C-6.1.
The AWS D1.1 Structural Welding Code (Steel) welder qualification plate tests consists of a groove weld with a 45-degree included angle. The plates are prepared to a knife’s edge and a ¼ in [6 mm] backing strip is used. The test for unlimited thickness will use plates that are 1 in [25 mm] thick. Anything less than that will qualify the welder for two times the thickness used in the test. Below is an example of a test that will qualify the welder to weld up to ¾ in [20 mm].
Welder performance qualification test for limited thickness.
The backing bar should extend the length of the test plates or could be slightly longer to allow for a run-on and run-off tabs. It should be 1 in [25mm] wide (3 in [75 mm] wide if it will not be removed when radiographic inspection is used for evaluating weld soundness in lieu of bend tests) and ¼ in [6 mm] to 3/8 in [10mm] thick.
As stated previously, radiographic testing may be used in lieu of bend tests. Procedures, technique and acceptance criteria for this type of test is provided in Clause 8 (Inspection) of AWS D1.1/D1.1M:2020 Structural Welding Code – Steel (Clause 6 if you are still using the 2015 edition). Tests must meet visual inspection and bend test criteria set forth in AWS D1.1 prior to testing. Step #1: You must request permission from your instructor to test. Step #2: Complete Welding Performance Qualification Test Form. Check it for accuracy. All tests are submitted for x-ray or bend examination to AWS D1.1.
More than 50 years, Ferroli produces climatic, heating and auxiliary equipment, including boilers. The equipment Ferroli is distinguished by reliability, safety, efficiency, modern design and low prices. The boiler is leaking from below. If water is leaking from your boiler from below, it could be a. Ferroli boiler fh fault. Ferroli boiler fault code fh The FH is not actually an error code. It just indicates forced removal or air from the system. The circulation pump is switched on for 3 minutes to drain the heating system of air. The use of Ferroli boilers for hot water supply systems is an ideal solution for those cases, when a high flow rate of hot water is required. There are other cases, when Ferroli boilers are an ideal solution. Ferroli boiler troubleshooting system provided in the table below is an ideal solution for diagnostics of any Ferroli appliance. Code fault b2 on my ferroli optimax plus 31c. Click here for how to mend it. Connections on Ferroli F24 Gas Valve? Anyone know the connections and expected voltages on the gas valve VK4105G fitted on a Ferroli boiler. Mine is not operating correctly and I want to determine if the fault is with the valve or the supply coming from the control.
Acceptance Criteria
In order for the welder to successfully pass this test, he or she must pass both visual inspection and meet the weld soundness acceptance criteria. Soundness is tested by performing bend tests or by radiographic inspection.
In order to pass visual inspection the weld must:
- Have no cracks of any size
- Craters must be filled to the full cross section of the weld
- The weld must not exceed 1/8 in [3mm] reinforcement
- Undercut must not exceed 1/32 in [1mm] in depth
- Additional requirements apply for tests that have an open root (no backing)
In order to pass weld soundness by bend tests the specimens must:
- Be bent according to the specifications of the code (different bend radii are specified depending on the base metals yield strength).
- The bent specimens should:
- Not exhibit any discontinuities greater than 1/8 in [3mm] in length
- Have no discontinuities greater than 1/32 in [1 mm] in length that combined add up to a total of more than 3/8 in [10mm]. Any single discontinuity exceeding 1/8 in [3 mm] constitutes a failure as seen in “a” above.
- Corner cracks should not exceed ¼ in [6 mm] in length. If the crack is a result of slag inclusion then the maximum length cannot exceed 1/8 in [3 mm]. If a corner crack with no evidence of slag inclusion is present and exceeds ¼ in [6 mm] in length the test specimen is discarded and new specimen cut from the original test plate must be tested. Corner cracks may be the result of poorly prepared tests specimens.
3. As stated previously, radiographic testing may be used in lieu of bend tests. Procedures, technique and acceptance criteria for this type of test is provided in Clause 8 (Inspection) of AWS D1.1/D1.1M:2020 Structural Welding Code – Steel (Clause 6 if you are still using the 2015 edition).
Welding Positions Qualified
It is sometimes incorrectly assume that the 1G test described above qualifies the welder for all positions. The qualified positions are based on the position used for testing. In this case, the 1G (flat) position for a plate groove weld test will qualify the welder for 1G as well as 1F and 2F (horizontal and flat fillet welds).
For additional information see Table 6.10 of your AWS D1.1 (2020) code book. It provides all the details on welding positions for welder performance qualification. Table 6.11 details the range of thickness qualified.

Aws D1.1 Visual Acceptance Criteria
We administer tests on a regular basis. When working strictly as a CWI we provide no guidance when taking these tests. When we are working as consultants we provide training and provide proper instructions in order to increase the probability of a successful plate test. In next week’s article we will expand on this.
