WELD PROFILER

MAC’s Weld Zone Profiler is designed to monitor the weld quality of a tube by depicting the “profile” of the completed weld.  Unacceptable weld profiles can indicate potential problems associated with irregularities in the scarfing and trimming process, a reduction in the weld size, and other anomalies which compromise the performance of a welded tube.

This system incorporates our Echomac® FD electronics, with custom Echohunter® software for profile monitoring, ultrasonic test head mechanics, pillar and guide unit, 1 transducer providing 1 channel for wall/weld profile, downstream video monitoring, and an optional off-line calibration station.

  • Pillar and gantry unit for support and stabililzation of test head.
  • Special ride shoe to withstand harsh environments.
  • Couplant for UT using bubbler technique.
  • Custom designed test head scans the weld zone.
  • A-Scan display of profile waveform and strip chart profile view, tracking and recording.

ULTRASONIC TECHNOLOGY IN NDT

High-speed Ultrasonic (UT) Systems enable a full volumetric examination of materials and are designed to detect surface, subsurface, internal and dimensional flaws.

This type of testing utilizes high-frequency sound waves that are transmitted throughout the material being tested in order to conduct a thorough inspection.

  • Ultrasonic inspection can be used to detect surface flaws, such as cracks, seams, and internal flaws such as voids or inclusions of foreign material. It’s also used to measure wall thickness in tubes and diameters of bars.
  • An ultrasonic wave is a mechanical vibration or pressure wave similar to audible sound, but with a much higher vibration frequency. For NDT purposes, the range is usually from 1MHz to 30MHz or higher.
  • Depending on the test requirements, these waves can be highly directional and focused on a small spot or thin line, or limited to a very short duration.
  • Two methods of UT are used for flaw detection – Shear and Compression Wave.
