INSPECTION AND REPAIR OF ADHESIVE-BONDED JOINT USING ULTRASONIC PULSES

摘要

A method of inspection and repair of a joint in an assembly. The joint is formed by a first work piece and a second work piece. An adhesive placed between the first and second work pieces to define the joint. The assembly includes an ultrasonic welding device including an ultrasonic horn configured to deliver ultrasonic energy to the joint. A controller is operatively connected to the ultrasonic welding device. The controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of inspecting and repairing the adhesive-bonded joint. The controller is programmed to deliver a first ultrasonic pulse (P1) to the joint, via the ultrasonic welding device, and determine an adhesive coverage (AC) based at least partially on the first ultrasonic pulse (P1).
