About Thick material inspection (TMI)

Application fields

  • Production type: thick-walled tubes with a longitudinal weld seam; welded seams can be tested in their full thickness
  • Materials: austenitic steel, aluminum, brass
  • Production line: inline production

Technical data

  • Hardware: EDDYCHEK 5 TMI
  • Inspection speed: up to 12 m/min
  • Penetration depth: up to 12.5 mm (greater wall thicknesses upon request)
  • Display: single channel differential

TMI is a new testing method developed specifically for the detection of flaws in thick-walled tubes, especially in weld seams. It operates at low cost in applications where ultrasonic inspection cannot be used. An external probe and testing unit developed for this application are installed right in your production line. Testing and marking of defects can take place immediately following production. Thus, this method achieves a high degree of efficiency.
