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

Cold heading machines

In the manufacture of small parts using cross-cutting or cold heading machines, high scrap rates often result from defective starting material. Testing the initial material and cutting out the defecti

Compound tubing

  • Inspection: Identification of weld seam defects in the internal metal layer of compound tubing
  • Diameter: 10-60 mm (0.4-2.4 in)
To guarantee a

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

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,
