Compression connection process monitoring and control method using evaluation of ultrasonic pulses reflected from boundary surface between joined components

摘要

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. An Independent claim for a compression connection device for joining 2 components is also included.
