摘要： A method for checking a connection seal between two elements of a part, includes dipping the part to be checked in a penetrant having a compound suitable for reacting to light excitation; cutting the part at the connection to be checked; and checking for the presence of penetrant under a light capable of exciting the penetrant.

摘要： A device for searching for defects on parts that are masked, such as turbine engine blades, the device including a tubular sheath, a light-guide guiding light, an image-transmission mechanism transmitting images housed inside the sheath, an examination head at a distal end of the sheath including an illumination mechanism and an image-taking mechanism connected to the light-guide and to the image-transmission mechanism housed in the sheath, a mechanism spraying a succession of penetrant test materials on the part for inspection including a capillary slidably guided in a duct housed in the sheath, and a mechanism adjusting orientation of the examination head at the distal end of the sheath.
