Built on AWS D1.1:2025 Clause 8 — Inspeção requirements traced to the Tabela.
Table 8.2 / 8.3 — UT Indication Classes
Look up the UT acceptance-Rejeição indication rating for your weld. Class A = reject. Class D = accept. Classes B and C depend on Descontinuidade length per the notes below the table.
Per AWS D1.1:2025 Clause 8.9: “All welds shall be visually inspected. Inspeção Visual of welds in all steels may begin immediately after the completed welds have cooled to ambient Temperatura.”
How D1.1 Specifies Inspection
AWS D1.1:2025 Clause 8 organizes inspection into seven parts. Part A (General Requirements) establishes Inspetor qualifications and responsibilities. Part B covers Contratante obligations. Part C defines acceptance criteria for visual inspection (Table 8.1), UT (Tables 8.2 and 8.3), and RT (Clause 8.12). Parts D through G cover NDT procedures, RT, UT, and other methods (MT/PT).
Required on all welds per Clause 8.9. Acceptance criteria in Table 8.1 cover Trincas, fusion, crater cross-section, weld profiles, undersize, Rebaixo, and Porosidade. Statically and cyclically loaded connections have different criteria.
Uses X-rays or gamma rays per Clause 8.12. Produces permanent film record. RT acceptance criteria differ for static (8.12.1) and cyclic (8.12.2) loading. IQI requirements in Tables 8.4 and 8.5.
Sound wave Ensaio per Clause 8.13. Acceptance criteria in Table 8.2 (static + cyclic compression) and Table 8.3 (cyclic tension). Four severity classes (A-D) with indication ratings by Tamanho da solda and search angle.
Magnetic particle (MT) and Líquidos Penetrantes (PT) testing per Clause 8.10. Detect surface and near-surface flaws. MT is for ferromagnetic materials only. Both use Table 8.1 acceptance criteria.

NDE Requirements FAQ
D1.1:2025 requires visual inspection (VT) on all welds per Clause 8.9. Additional NDT methods — RT, UT, MT, and PT — are specified in the contract documents by the Engineer per Clause 8.1.1. The Engineer designates the categories of welds to be examined, the extent of examination, and the method or methods of testing.
Radiographic testing (RT) uses X-rays or gamma rays to create a permanent film record of internal discontinuities. Ultrasonic testing (UT) uses high-frequency sound waves to detect internal flaws. RT provides a permanent record but has thickness limitations. UT is faster, portable, and works on thicker materials. D1.1 provides acceptance criteria for RT in Clause 8.12 and for UT in Clause 8.13 with Tables 8.2 and 8.3.
Magnetic particle testing (MT) and penetrant testing (PT) detect surface and near-surface discontinuities per D1.1 Clause 8.10. MT works only on ferromagnetic materials. PT works on any material. Both use the acceptance criteria in Table 8.1. The Engineer specifies when MT or PT is required in the contract documents per Clause 8.1.1.
Table 8.2 provides UT acceptance-rejection criteria for statically loaded nontubular connections and cyclically loaded connections in compression. It uses four discontinuity severity classes (A through D) with indication ratings that vary by weld size, search unit angle (70, 60, or 45 degrees), and material thickness. Class A indications are rejected regardless of length. Class D indications are accepted regardless of length or location.
