摘要： A system for non-destructively characterizing laser welds that includes at least one phased array probe that includes a plurality of ultrasonic transducer elements arranged in an array at one end of the probe, wherein the transducer elements are operative to both generate ultrasonic signals and to receive reflections thereof, wherein the transducer elements are further arranged into discrete subgroups, and wherein each subgroup may be activated independently of the other subgroups and at different time intervals; a combination of materials for allowing the probe to conform to a contoured surface of a laser weld while enabling sound energy to be transferred directly into a laser weld under test conditions, wherein the combination of materials further includes a flexible membrane mounted on the end of the probe and a fluid filled chamber material disposed between the membrane and the array of ultrasonic transducer elements; and a data processor in communication with the at least one phased array probe that includes software having at least one imaging algorithm for processing data received from the probe and generating color coded ultrasonic C-scan images of a characterized laser weld.

摘要： A method for characterizing a spot weld, including acquiring a sequence of A-scans from an ultrasonic phased array, wherein the A-scans describe individual portions of a field of view of the phased array; manually applying an interface gate and a flaw gate to each individual A-scan within the sequence of A-scans; calculating a gate ratio between a maximum amplitude under the interface gate and a maximum amplitude under the flaw gate for each individual A-scan; plotting the gate ratio for each individual A-scan as a function of location within the phased array field of view to generate a weld fusion map; using a predetermined threshold to differentiate fused locations from unfused locations on the weld fusion map; and calculating predetermined weld metrics, wherein the predetermined weld metrics include area, diameter, width, length, percent fused, or combinations thereof.
