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

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)

Multivoid tubing

Air conditioner tubing is inspected inline after extrusion. An encircling coil tests for outer surface defects and checks that the walls of the interior chambers are intact. It is spec

Continuous drawing line

  • Input control: Identification of bad quality rolled wire (drawing lines for thick wire)
  • Process control: Monitoring of production lines to avoid scrap (medium and fine drawing bloc

Fine wire

  • Inspection: Continuous inspection using encircling coil
  • Wire characteristics: Diameters down to 0.05 mm; tungsten, molybdenum, etc.
  • Production line: Drawing and rewinding lines
