This paper gives study of design of a wet leak test machine, used for the detection of leakages in radiators. It is based on the technique of submerging the part in the water that is stored in an immersion tank. Immersion tanks are a widely used method for location of leakages in complex assemblies and products. The part under test is pressurized with air while being submerged in a liquid, typically water. The operator looks for a stream of bubbles indicative of a leak. Proper selection and implementation of a production leak test method starts with an understanding of why the test is being performed, followed by establishing what the leak rate limit is, and finally a determination of how the leak test will be performed.

Keywords: leak test, immersion tank, stream of bubbles, sensitivity, cost effective and reliable
