Abstract: A method for planning an agricultural post-processing operation along a post-processing route includes carrying out an agricultural pre-processing operation by a pre-processing machine along a pre-processing route, using a recording system to record the pre-processing route, determining the post-processing route to be worked by a post-processing machine on the basis of the recorded pre-processing route. The recording system records a processing setting of the pre-processing operation and the planning device determines the post-processing route on the basis of the processing setting.

Abstract: A device for ultrasonic weld seam testing of longitudinally includes two testing carriages swingably suspended and moveable on the pipe surface to the right and left of the weld seam for longitudinal flaw inspection, and one testing carriage swingably suspended in central relationship to the weld seam and moveable on the pipe surface for transverse flaw inspection. Each testing carriage has a mount for accommodating at least one testing head which includes an oscillator, and at least one coupling medium connection having a channel ending in the region of the oscillator and configured as nozzle in the outlet area. The test head for longitudinal flaw inspection can be arranged at various fixed and predefined angle positions at variable distance to the nozzle in the mount, and the test head for transverse flaw inspection can be arranged, together with the mount, at a variable distance to the pipe surface in a support element accommodating the mount.

Abstract: The invention relates to a device for ultrasonic weld seam testing of longitudinally welded pipes for longitudinal and transverse flaws, including two testing carriages which are swingably suspended and which can be moved on the surface of the pipe to the right and left of the weld seam for longitudinal flaw inspection, and one testing carriage which is swingably suspended, oriented in central manner with respect to the weld seam, and which can be moved on the surface of the pipe for transverse flaw inspection. Each testing carriage is provided with a transducer for accommodating at least one testing head which includes an oscillator, and at least one coupling medium connection having a channel which ends in the region of the oscillator and is configured as a nozzle in the outlet area. The respective nozzle element is connected to the transducer by means of screws.
