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

Seamless tubing

  • Inspection: Encircling coil for full-body inspection. For a more thorough inspection, a rotating system is used simultaneously for identifying longitudinal grooves.
  • Production typ

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

Sensitive bar testing

Application fields

  • Production type: very high quality bars and seamless tubes
  • Materials: round black or bright steel (ferromagnetic); rolled, straightened or sand blasted
  • Diamet
