About Weld seam testing

  • International test standards: Weld seam testing according to SEP, DIN, STM, PI, BS, JIS, ETTC, ENEL, etc.
  • Welding lines: All welding methods such as TIG, laser, HF and ERW welding
  • Materials tested: Ferrous, austenitic, duplex grades, nonferrous aluminum, copper, brass, titanium and german silver
  • Combination inspection: Simultaneous weld seam testing and full-body inspection
  • Line speeds: 0.1-200 m/min (0.3-660 fpm)
  • Tube sizes: 0.5-600 mm (0.2-23½ in)
Eddy current testing readily identifies flaws in the weld seam regardless of what welding procedure is used. The defects are color-marked and the tube is assigned a sort class according to its quality. Test results are fully documented for future reference.PRÜFTECHNIK offers a wide variety of eddy current inspection units that range from the most basic testers to powerful inspection systems with wide-reaching capabilities for integration into central production control systems and 8-channel inspection using multiple coil systems.

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
  • Inspectio

Hot rolled ferritic rod

  • Quality control: Detection of defective areas in test material and assignment of test piece to a quality category 
  • Process control: Identification of defective rolling element

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
