The invention refers to a method for on-site X-ray inspection of a cable sealing end termination of a high-voltage cable in joint condition, such as found when inspecting gas insulated switchgear of electrical high voltage sub-stations, comprising the following steps: - providing a radiation generator (8) capable of emitting upon energization electromagnetic waves with a wave length and a photon energy in the x-ray range, - providing a photographic recording media (9) sensitive to the electromagnetic waves, - placing the recording media (9) and the radiation generator (8) at opposite sides of the cable sealing end termination such that the radiation generator (8) is directed towards the cable sealing end termination as a x-ray target, - energizing the radiation generator (8) at least once in order to record at least one x-ray image, - providing at least one reference image of a cable sealing end termination as a test target, - comparing the x-ray image with the reference image and subsequently assessing the sealing integrity of the cable sealing end termination.

Aspects of the disclosure are directed to an analysis of a material of a component 322a-c. A radiation source 304 is activated to transmit radiation 310 to the component 322a-c. A beam pattern is obtained based on the component 322a-c interfering with the radiation 310. The beam pattern is compared to a reference beam pattern. An anomaly is detected to exist in the material when the comparison indicates a deviation between the beam pattern and the reference beam pattern.

Method for manufacturing a control blade for calibrating a non-destructive tomographic inspection of actual blades that are similar in terms of shape and size. The method consists in producing a three-dimensional blank (10) from resin, creating housings (12, 14) in the thickness of this blank at predetermined locations, and introducing into each of the housings a cylinder (22, 24) comprising an artificial or actual defect in order to obtain the control blade.
摘要:
Die Erfindung betrifft ein Verfahren zur automatisierten Fehlererkennung in Werkstücken (26) mittels einer Röntgenprüfanlage (2) mit einer Röntgenstrahlenquelle (6) und einem Röntgenstrahlendetektor (8), bei welchem die Röntgenprüfung in einer definierten Stellung des Werkstücks (26) zwischen der Röntgenstrahlenquelle (6) und dem Röntgenstrahlendetektor (8) erfolgt und bei welchem die Werkstückstellung optisch erfasst und eine Abweichung von der definierten Stellung ermittelt wird. Hierbei werden die Röntgenstrahlenquelle (6) und der Röntgenstrahlendetektor (8) entsprechend der ermittelten Abweichung so verfahren, bis das Werkstück (26) in der definierten Stellung zwischen der Röntgenstrahlenquelle (6) und dem Röntgenstrahlendetektor (8) angeordnet ist.
