Destructive testing of butt fusion welding

The quality of a weld joint is crucial when manufacturing a butt fusion weld in a PE piping system. Normec QS guarantees the quality of PE butt fusion weld connections by:

  • Control of preparations and welding parameters before the start of the welding process
  • Control during and after the welding process on site
  • Visual inspection of test welding and field welding on location and in our own laboratory
  • Ultrasonic ToFD examinations of field welding on site
  • Non-destructive testing on site and in our own laboratory
  • Destructive testing of test welding and field welding in our own laboratory

Destructive testing of test welding and field welding

In its own laboratory, Normec QS has accredited facilities for the preparation and testing of butt fusion welding in accordance with the applicable standards. We can perform the following tests on both representative test welding and field welding:

  • Tensile tests PE butt fusion welding – according to NEN 7200:2017
  • Tensile tests PE butt fusion welding < 90 mm – according to ISO 527-1 and ISO 527-2
  • Tensile tests PE butt fusion welding > 90 mm – according to ISO 13953

Use of elongation tests

By carrying out tensile tests, Normec QS checks whether butt fusion welds are strong enough and meet the set requirements. Its quality is measured on the basis of applicable international ISO-NEN standards.

Non-destructive testing (NDT examination)

In addition to destructive testing of butt fusion welding, Normec QS offers the possibility of non-destructive testing (NDT) of butt fusion welding. This takes place through visual inspection and ultrasonic ToFD examination.
