AMS 2630 — Ultrasonic Inspection for Thick Metal Products

AMS 2630 defines pulse-echo ultrasonic testing (UT) requirements for metallic products ≥ 0.50 in (12.7 mm) in thickness or cross-section, using contact or immersion methods and longitudinal and/or shear waves to detect internal discontinuities. The standard can also apply to finished parts when size, contour, structure, and thickness meet baseline testability.

What Does AMS 2630 Cover?

• Products: flat, rectangular, round, cylindrical, and contoured sections over 0.50 in (12.7 mm) thick

• Ultrasonic method: pulse-echo, using contact or immersion coupling

• Wave modes: longitudinal (volumetric screening) and shear (planar-flaw sensitivity)

• Finished parts: permissible when geometry allows full sound entry and evaluation

Test Methods Under AMS 2630

Contact Ultrasonic Inspection

• Used when only one surface is accessible, or for large plates, bars, forgings, or field testing

• Setup: handheld or mechanized probe with couplant; calibrated using approved reference blocks

• Advantages: flexible, fast, minimal equipment footprint

• Consideration: consistent coupling and controlled probe pressure are required for clean signals

Immersion Ultrasonic Inspection

• Used for highest repeatability, finer detectability, and complex profiles

• Setup: part submerged in water; transducer scans with controlled index and positioning

• Advantages: excellent coupling, small defect detection, precise mapping and recording

Wave Modes Specified by AMS 2630

Longitudinal Waves

• Deeper penetration and rapid volumetric screening

  
  

Shear Waves

• Higher sensitivity to planar flaws such as cracks or lack-of-bond conditions

Often used together for full coverage.

Calibration, Sensitivity & Equipment (Overview)

• Reference standards: FBH, SDH, or artificial reflectors as defined by drawing/PO

• Sensitivity set to required reflector amplitude; document transfer corrections when substitutes are used

• Scan plan: 100% of required zones; controlled index and scan speeds to avoid skip or dead areas

• Couplants: qualified for material and temperature, maintaining stable transmission

• Traceability: record probe IDs, frequency, gain settings, reference responses, and part IDs

Acceptance & Disposition

• Indications evaluated against reference levels defined by drawing or PO

• Reports include part ID, scan maps, instrument setup, calibration data, indication sizes/locations, and pass/fail status

• Nonconformance: re-scan, alternate wave mode, immersion check, or engineering review

Choosing the Right Ultrasonic Standard

Tip: Rings, thin plates, or small geometries may require AMS 2632 instead of AMS 2630.

Industries & Typical Applications

• Aerospace: bars, plate, billet, and forgings for rotating and structural components

• Energy & Oil/Gas: heavy-wall components and pressure-critical stock

• Medical & Industrial: high-reliability metallics requiring internal soundness
