Aws D1 1 Radiography Acceptance Criteria



  1. 03:26 Feb-21-2017 AWS D1.1 - UT requirements X or XF acceptance criteria. I have a question for AWS D1.1 acceptance criteria. When we find an indication at scanning level using primary procedures selected from tab. 6.7, in case of discontinuity indication located at weld-base metal interface, the scanning requirements X or XF have to be applied.
  2. If you are a CWI/CAWI testing to D1.1 between the dates of July 4th, 2020 and December 31st, 2020, you can use either edition (2015 or 2020) of the D1.1 codebook. If you are taking an AWS Seminar, You will be using the 2015 edition.

AWSD1.1 RT Acceptance Criteria
Welds that are subject to RT in addition to visual inspection shall have no cracks and shall be unacceptable if the RT shows any discontinuities exceeding the following limitations (E = weld size).

PRG Practical Reference Guide for Radiographic Inspection; Acceptance Criteria: Easy orientation to the levels of potential weld discontinuities that wont affect the weldments.

1. To see detail RT Acceptance Criteria for Statically Loaded Nontubular connections you can open Section 6.12.1 AWS D1.1 and Figure 6.1 , Figure 6.2 , Figure 6.3 .
2. To see detail RT Acceptance Criteria for Cyclically Loaded Nontubular Connections you can open Section 6.12.2 AWS D1.1 and Figure 6.4 .
The limitations given by Figures 6.4 and 6.5 for 1-1/2 in. [38 mm] weld size shall apply to all weld sizes greater than 1-1/2 in. [38 mm] thickness.
3. To see detail RT Acceptance Criteria for Tubular Connections you can open Section 6.12.3 AWS D1.1 and Figure 6.6

AWSD1.1 Visual Inspection Acceptance Criteria
All welds shall be visually inspected and shall be acceptable if the criteria of Table 6.1 AWS D1.1 are satisfied.
To more explanation about Visual Inspection Acceptance Criteria you can open AWS D1.1 section 6 (inspection) part C.

Before you inspect and make decision about weld as per AWS D1.1, you must know definitions of:
1. Statically Loaded Nontubular Connections (more detail see Section 2 part B AWS D1.1)
2. Cyclically Loaded Nontubular Connections (more detail see Section 2 part B,C AWS D1.1)
3. Tubular Connection (all Load) (more detail see Section 2 part D AWS D1.1)
Below Summary Visual Inspection Acceptance Criteria As per AWSD1.1 Table 6.1 :
- Any Crack shall be unacceptable, regardless of size or location
- All craters crack (start/end) shall be filled, except for the end of intermittent fillet weld outside of their effective length
- All weld profiles shall be free from cracks, overlaps, and the unacceptable profile discontinuities exhibited in Figure 5.4.

Aws D1.1 Ut Acceptance Criteria

Aws D1 1 Radiography Acceptance Criteria
- Visual inspection of welds in all steels may begin immediately after the completed welds have cooled to ambient temperature. Acceptance criteria for ASTM A 514, A 517, and A 709 Grade 100 and 100 W steels shall be based on visual inspection performed not less than 48 hours after completion of the weld.
- The size of a fillet weld in any continuous weld may be less than the specified nominalsize (L) without correction by the following amounts (U) on Table 6.1
- Undercut and porosity see more detail on Table 6.1
Methods of Testing and Acceptance Criteria for WPS Qualification (Section 4) Visual Inspection.
For acceptable qualification, welds shall meet the following requirements:

Aws D1 1 Radiography Acceptance Criteria Example

(2) All craters shall be filled to the full cross section of the weld.
(3) The face of the weld shall be flush with the surface of the base metal, and the weld shall merge smoothly with the base metal. Undercut shall not exceed 1/32 in. [1 mm]. Weld reinforcement shall not exceed 1/8 in. [3 mm].
(4) The root of the weld shall be inspected, and there shall be no evidence of cracks, incomplete fusion, or inadequate joint penetration. A concave root surface is allowed within the limits shown below, provided the total weld thickness is equal to or greater than that of the base metal.
(a) The maximum root surface concavity shall be 1/16 in. [2 mm] and the maximum melt-through shall be 1/8 in. [3 mm].
(b) For tubular T-, Y-, and K-connections, melt-through at the root is considered desirable and shall not be cause for rejection.
