About Test Defect Saw

Portable unit to saw standard defects in tubes, rods and billets

  • For sawing precise slots of standard depth, width and length used in calibrating eddy current test equipment
  • Small and light construction for convenient transport to test pieces on location
  • Narrow design for fitting between rollers, etc.
  • Simple switch between positions for sawing 0°, 45° and 90° slots
  • Can be used for grinding and sawing hard or soft materials
  • Available with self supporting bar or wire holder
  • Slot depth accuracy: 0.02 mm
Before it is used to test material, eddy current inspection equipment is precisely calibrated to find the defects specifically required by international standards (API, ASTM, etc.). To do this, test defects of a standard depth, width and length are sawed into a test piece. This has always been a challenge when faced with transporting massive billets and rods to a stationary test defect saw.Now PRÜFTECHNIK introduces a new portable saw that you can take to the test piece while it is still in the conveyor. Thanks to its narrow dimensions, it fits easily between inline rollers. It quickly and accurately produces standard slots in tubes, rods and billets.We carry additional equipment for the calibration of eddy current inspection equipment. A special test defect saw is available for producing standard slots on the insides of tubes. In addition, we offer a test bench for use when calibrating the eddy current test equipment.
