WELD LINE TEST

Echomac® Weld Line Ultrasonic Test System.  Inspects tube weld quality during production.

Featuring new operating conveniences for inspecting tube weld zones on-line during continuous production, the system is designed to test for longitudinally oriented defects that are typical of the ERW welding process.NDT for Weld Line

These systems typically include four channels, using both CW and CCW sound modes for detection of ID and OD longitudinal defects between 5% and 10% of wall thickness. Additional channels can be added, depending on the application.

  • Includes MAC’s highly regarded Echomac® instrumentation with Echohunter® software.
  • Test head incorporates transducer assemblies, with irrigated shoes, to provide constant coupling with the tube being tested.
  • Test head is supported by a pillar mechanism that allows it to operate on the weld line for mill testing, or off line for easy calibration for a new tube size.

ULTRASONIC TECHNOLOGY

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.Non Destructive Testing with Ultrasonic Technology

  • 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.
