Ultrasonic Testing

Locating Defects; Measuring Wall Thickness

Ultrasonic Testing, also known as UT testing or ultrasonic non destructive testing, can locate internal and external product defects and measure wall thickness discontinuities in metal tubing, pipe, bar stock and other materials without causing damage during inspection.

Providing Fast Turnaround and More

Computerized UT testing systemsLaboratory Testing Inc. near Philadelphia, PA (USA) performs both contact and immersion ultrasonic testing. The lab is set up to provide fast test results:

  • Five high-speed immersion UT testing systems
  • Fully staffed first and second work shifts
  • In-house services:
    • Receipt and final inspection, cutting
    • Trimming and deburring
    • Material identification
    • Special packaging and shipping

Our in-house collection of over 2,000 UT reference standards for tubing, pipe, bar and plate makes fast turnaround easy. Other standards can be quickly manufactured in our own Machine Shop or by our qualified local vendor.

The Ultrasonic Testing Process

During the ultrasonic test, an ultrasound probe connected to the test equipment transmits short pulses of high-frequency sound waves into the item being inspected while passing over its surface. A defect or inconsistency will cause some of the energy to be reflected. Sound pulses are displayed on a screen when reflected from features within the test material. The technician interprets these reflected signals to determine if the product or material is defective or acceptable according to the test specification or requirements.

Immersion ultrasonic testing takes place in a liquid which conducts the sound waves between the probe and test material. The process is partially automated and eliminates the need for direct contact with the test material during inspection. An ultrasonic probe emitting sound waves is manually run over the surface of the test piece during contact ultrasonic testing. When it can be used, the immersion method is preferred because it can be faster and more accurate.
