Verfahren zur Ueberwachung und gegebenenfalls Steuerung des Fuegeprozesses beim Durchsetzfuegen

DE 10208304 C UPAB: 20031203 NOVELTY - The method has repetitive ultrasonic pulses supplied to the joined components during the connection process via ultrasonic transducers (7,8) incorporated in both the die (1) and the matrix (2) of the compression device, with measurement of the propagation times of the ultrasonic pulses reflected from the boundary surface between the joined components, for comparison with reference values for each component corresponding to the plastic deformation upon reaching the required joint thickness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM for a compression connection device for joining 2 components is also included. USE - The method is used for monitoring and control of a compression connection process for joining 2 components. ADVANTAGE - Evaluation of reflected ultrasonic waves allows monitoring of obtained joint thickness
