摘要： The invention relates to a method for filtering measurement signals by way of wavelet filtering, wherein the signals are first transferred to the wavelet domain by way of a wavelet transform, are subjected to threshold analysis, and the threshold values can then be varied in the wavelet domain relative to the respective measurement situation. The measurement signals are filtered by means of a plurality of filters in segmentation levels and a statistical parameter is calculated based on an adjustable number of already calculated wavelet coefficients of a segmentation level and is then multiplied with a value that can be adjusted for all levels together to determine the threshold value of the respective segmentation level.

摘要： 2.1.The invention relates to a process for the destruction-free testing of metallic pipes, in particular seamlessly produced steel pipes, in which method the entire length of the pipe is scanned following the circumference precisely and in this case, in addition to the wall thickness (WD) and the external diameter (Da) being determined, the inner and outer surfaces of the pipe are examined for faults, the faults determined in this process are compared with a predefined permissible reference fault depth RFT (RFT = fault threshold of x % of the nominal wall thickness), the pipes are sent to reworking means if the fault threshold is exceeded, and a requisite minimum wall thickness (WD min) has to be present in the reworked region after the processing has been carried out. 2.2. For this purpose, the invention provides for the pipes containing faults to be released for reworking only when the determined geometrical parameters have been correlated with one another beforehand in an evaluation step, and the following conditions are met: WD - RFT > WD min for faults on the inner and outer sides of the pipe and Da - RFT > Da min for faults on the outer side of the pipe.

摘要： The invention relates to a traction rod (1) for bracing a crane jib, comprising a metallic tubular body (2) and coupling elements (3) which are connected to both ends thereof for an articulated connection of the traction rods among each other by means of bolts (5). According to the invention, the tubular body and the coupling elements consist of a one-piece tube portion, wherein the coupling elements are designed in each case as a thicker zone of the wall of the ends of the tubular body and are dimensioned in such a manner that a weakening of the cross section of the nominal wall thickness of the coupling elements, which has to be considered for calculating the load capacity of the tubular body, is prevented in the region of the bolt connection and the transition regions (7) from the respective thicker zones of the wall in the direction of the tubular body have a transition free of starting points for increasing fatigue strength.

摘要： The invention relates to a method for testing pipes (1) in a non-destructive manner with the aid of a dispersion flow, said pipes being made of ferromagnetic steel. According to the invention, the pipe which is displaced in the longitudinal direction and, optionally, rotated is magnetised by a continuous field and the produced magnetic flow is transmitted in a contactless manner to the pipe. Projections (4, 4') which are located in the areas close to the surface of the external and internal surfaces of the pipes provoke magnetic dispersion flows which exit the surface of the pipe and can be detected by sensors (2, 2'). Ampltitudes, preferably the horizontal field components of the magnetic flow, which can alter in the vertical direction are detected at a distance close to the surface of the external surface of the pipe and at a distance therefrom. The detected signals are determined in relation to each other. The invention also relates to the device for carrying out said method.

摘要： The invention relates to a method for the nondestructive testing of pipes made of ferromagnetic steel for flaws by means of leakage flux, wherein the pipe is magnetized by a constant field and the flaws present in the near-surface region of the outer or inner surface of the pipe cause magnetic leakage flux, which exits the pipe surface and is detected by probes of a test unit each for longitudinal and/or transversal flaw testing, wherein the association of the detected amplitude signals is performed on the basis of the amplitude height and/or the frequency spectrum with respect to an outer or inner flaw by external or internal flaw thresholds. To this end, prior to associating the detected amplitude signals with an external or internal flaw, the angular position of the flaw relative to the respective magnetic field direction is determined, and a correction of the signals is carried out by way of a previously determined corrective factor for amplitudes and/or frequencies.

摘要： Kranbahntragsystem aus Stahl für hohe Beanspruchungen bestehend aus einem Obergurt und einem damit verbundenen Stegblech (3), an dem ein Untergurt angeschlossen ist und einer auf dem Obergurt (1) angeordneten Kranbahnschiene (6). Um bei einem derartigen System den Fertigungsaufwand zu verringern und die kostengünstige Herstellung zu ermöglichen, wird vorgeschlagen,
dass Obergurt (1), Stegblech (3) und Untergurt (4) als ein integriertes Tragsystem ausgebildet sind, wobei der Obergurt (1) aus zwei in Längserstreckung nebeneinander angeordneten Rohrkörpern (2,2') besteht, zwischen denen das mit in Längsrichtung in einem festgelegten Raster beabstandeten Quersteifen (5) versehene Stegblech (3) angeordnet und mit ihnen fest verbunden ist, wobei sich das obere Ende des Stegbleches (3) maximal bis zur Oberkante der Rohrkörper (2,2') erstreckt.
