Abstract
Unintended leaks in pressurized components and systems, such as engine blocks, radiators, A/C components, fuel systems, torque converters and transmission housings, may be detrimental to consumers, manufacturers and the environment. Quick and reliable leak detection and localization are critical manufacturing quality-control processes for these products. This article presents a method for leak detection and localization based on photoacoustic sounds.
