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.

Reated Projects

Rotational testing

  • Products tested: All seamless products that are round or off-round
  • Production types: Straightening lines, continuous drawing lines, offline final inspection

Butt weld detection

Butt weld detection

Butt welds cannot be identified by simple detectors such as the light barrier or proximity switch. The EDDYSENSOR locates the butt weld using eddy current t

Sheathed products

Eddy current technology can be used to detect splices, connecting wedges or joint inside coated material such as steel tubes with PVC insulation. In this example, an EDDYSENSOR and an e

Inline testing

  • Input control: Identification of bad quality material, e.g. rolled wire (drawing lines for thick wire), bar, tube or pipe
  • Quality control: Detection of defective areas in tes
