Abstract
An apparatus for automatic leak detection includes a fixture having a primary seal and a secondary seal. The fixture connects to a workpiece to enclose a test volume defined in the workpiece. The seals are to interface with the workpiece to at least partially enclose a buffer volume. An enclosure is to connect to the fixture to enclose a test portion of the workpiece to form a test chamber. The secondary seal separates the buffer volume from the test chamber. The test volume and the test chamber have a tracer gas pressure differential between them. A port in fluid communication with the buffer volume removes fixture leakage from the buffer volume. A detector detects the tracer gas in the test volume or the test chamber where the tracer gas pressure differential between the test volume and the test chamber urges workpiece leakage of the tracer gas to accumulate.
