Normec QS contributes to certification pilot for European hydrogen requirements
During the manufacture of butt fusion welding in a PE piping system, the quality of the welding connection is of crucial importance. Normec QS guarantees the quality of PE butt fusion weld connections through a number of measures:
ToFD is a form of non-destructive (ultrasonic) examination using a scanner. In addition, an ultrasonicist from Normec QS sends precisely tuned sound waves through the inside of the butt fusion weld. This form of NDT research is a form of radiographic welding research. With ToFD, a scan results in a film image of the inside of a butt fusion weld on which, for example, possible air bubbles or grains of sand in the butt fusion weld become visible. Based on the results of the investigation, the inspector can determine whether there are possible unacceptable deviations.
Non-destructive testing performs one of our welding inspectorsin addition to visual inspection. By performing ultrasonic NDT examination, the welding inspector assesses the inside of a butt fusion weld. During the visual inspection, he inspects and assesses the outside of a butt fusion weld.
Non-destructive testing by Normec QS takes place alongside destructive testing in the Normec QS Testing laboratory. In NDT research, the butt fusion weld remains intact. In destructive testing, the strength of the impact weld is tested in the Normec QS laboratory by means of a tensile test.
