Trinity NDT

Ultrasonic Inspection Testing (UT) ISO17025 NABL Accredited NDT Labs at Bangalore India

Aerospace NDT | Welding Inspection | Training

Ultrasonic Testing or Ultrasonic Inspection as conventionally called as UT testing is one of the most widely used Nondestructive testing NDT method to find internal flaws using Ultrasonic waves to inspect Ingots, Castings, forgings, rolled plates, sheets, bars, rods, weld joints, shafts, gears, and other engineering components in cast, forged, machined condition, during manufacturing and in-service inspections. Ultrasonic thickness testing is also used for measuring remaining wall thickness using Ultrasonic principle.

Codes, Standards & Specifications on UT

Ultrasonic inspections are carried out as per approved NDT procedures and specifications such as ASTM E 114 – Straight Beam Ultrasonic testing, ASTM A 388 – UT of Heavy steel forgings. ASTM A 609 – UT of Castings, ASTM E 435 – Ultrasonic testing of plates using straight beam examination, ASTM A 577 – UT testing of plates for special applications, ASTM A 578 – Angle beam Ultrasonic testing of steel plates, American Welding Society AWS Structural Welding codes Acceptance Criteria for Ultrasonic testing – AWS 1.1, 1.3, National Aerospace Laboratories Specifications NDTS and other national and International Standards.

Most of the ultrasonic inspection instruments detect flaws by monitoring one or more of the following:

Ultrasonic thickness Gauging Test Facility

Ultrasonic thickness gauging is one of the effective tools to control wall thickness of pipes, tubes and other components during manufacturing and in-service inspection of boiler pipes, tubes, plates, castings, oil and gas pipe lines and other components to check wall thickness loss due to corrosion erosion and other loss mechanisms. Our NDT labs equipped with digital Ultrasonic thickness gauges and high temperature Ultrasonic probes for high temperature applications. Specially formulated couplants are available for LOX compatible applications and high temperature ultrasonic inspections.

Ultrasonic Inspection Applications

Ultrasonic testing or inspection (UT) is used for quality control and materials testing in all major industries. This includes Ultrasonic testing of castings, forgings, plates, extruded components, weld joints, electrical and electronic component manufacturing, production of steel, aluminum and titanium, fabrication of structures such as air frames, pressure vessels, ships, bridges, motor vehicles, machinery and jet engines. In service ultrasonic testing for preventive maintenance is used for detecting impending failure of rail road rolling stock axles, press columns, earth-moving equipment, mill rolls, mining equipment and other machines and components. The flaws to be detected include voids, cracks, inclusions, pipe, laminations, bursts and flakes. They may be inherent in the raw materials, may result from fabrication and heat treatment, or may occur in service from fatigue, corrosion or other causes. Ultrasonic testing can also be used to measure thickness of metal sections during manufacturing and maintenance inspections.

Ultrasonic testing Limitations

Ultrasonic testing Limitations

  1. Manual Ultrasonic Flaw detection requires careful attention by experienced technicians to carryout testing and evaluate inspection results
  2. Extensive technical knowledge is required for the development of Ultrasonic testing procedures. Download Sample Ultrasonic inspection procedure
  3. Parts that are rough, irregular in shape, very small or thin or non-homogenous materials are difficult to be tested using ultrasonic principle
  4. Discontinuities that are preset in a shallow layer immediately beneath the surface may not be detectable for which Surface NDT methods such as Liquid penetrant testing, Magnetic particle testing, Eddy current testing are recommended.
  5. Couplants are needed to provide effective transfer of ultrasonic wave energy between Ultrasonic probes and components being tested.
  6. Ultrasonic Reference standards are needed, both for calibrating the equipment and for characterizing flaws.

  7. Strong team of NDT professionals to provide ultrasonic inspection services across India

Most of the ultrasonic testing equipment detects flaws by monitoring one or more of the following:

  1. Reflection of energy from metal-gas interfaces, metal-liquid interfaces or discontinuities within the metal itself due to impedance mismatch
  2. Time of energy from metal-gas interfaces, metal-liquid interfaces or discontinuities within the metal itself due to impedance mismatch of transit of a Ultrasonic sound wave through the test piece from the entrance point at the sending (transmitting) transducer to the exit point at the receiving transducer, and
  3. Attenuation of the beam of sound waves by absorption and scattering within the test piece.
