Abstract:
A testing method for a joined body, in which a second pipe member having an outer diameter smaller than that of a first pipe member having at least one through hole is inserted into the first pipe member and the second pipe member is expanded to form a joining portion, the testing method includes: applying an elastic wave vibration to the joined body of the first pipe member and the second pipe member, for plural visual field regions at different positions in a circumferential direction of the joined body, acquiring a vibration distribution of the second pipe member measured through the through hole and a vibration distribution of the first pipe member in a visual field region including the joining portion of the first pipe member and the second pipe member, which are measured optically and in a batch, and determining quality of joining in the entire joining portion based on the acquired vibration distributions.
