Paper Abstract

The application of Nondestructive Evaluation, particularly ultrasonic evaluation, in the automotive components industry has been accelerated in the last several years. The quality and integrity of materials and structures employed for automotive components are routinely examined by radiographic, eddy current and ultrasonic methods. Some discontinuities can be detected with one or all of these methods. Certain defects, in the form of delamination, can only be detected by the ultrasonic method. Both manual testing and highly automated system have been used for ultrasonic testing of automotive components. The automated system is particularly attractive when high reliability is required for automotive components used in critical safety systems applications. This paper gives a practical overview of the application of ultrasonic evaluation in automotive component development and manufacturing. Areas covered include ultrasonic evaluation of materials, automated inspection of cold rolled components, and methodology for setting up acceptance and reject standards. This manuscript is focused on the ultrasonic application to safety related automotive components.
