Abstract
(EN) The present invention inserts a second tubular member (13) which has a smaller outer diameter than does a first tubular member (11) into the first tubular member (11), which has a through-hole (19), and tests the joined body (17) thereof in which a joined section (15) is formed by expanding the second tubular member. The present invention imparts elastic wave vibrations to the joined body comprising the first tubular member and the second tubular member, and for a plurality of visual field regions at different positions in the circumferential direction of the joined body, obtains a second tubular member vibration distribution measured through the through-hole and a first tubular member vibration distribution in a visual field region (IA) containing the welded section, the measurement of which is performed optically and in a batch. The present invention determines the quality of the joining in the joined section overall using these vibration distributions.
(FR) La présente invention insère un second élément tubulaire (13) qui présente un diamètre externe plus petit que celui d'un premier élément tubulaire (11) dans le premier élément tubulaire (11), qui présente un trou traversant (19), et teste le corps assemblé (17) de celui-ci dans lequel une section assemblée (15) est formée par expansion du second élément tubulaire. La présente invention confère des vibrations d'onde élastique au corps assemblé comprenant le premier élément tubulaire et le second élément tubulaire, et pour une pluralité de régions de champ visuel au niveau de différentes positions dans la direction circonférentielle du corps assemblé, obtient une seconde distribution de vibrations d'élément tubulaire mesurée à travers le trou traversant et une première distribution de vibrations d'élément tubulaire dans une région de champ visuel (IA) contenant la section soudée, dont la mesure est réalisée optiquement et sous forme de lot. La présente invention détermine la qualité de l'assemblage dans la section assemblée au moyen de ces distributions de vibrations.
(JA) 貫通孔(19)を有する第1管部材(11)の管内に、第1管部材よりも小さな外径を有する第2管部材(13)を挿入し、第2管部材を拡管して接合部(15)を形成した接合体(17)を検査する。第1管部材と第2管部材の接合体に弾性波振動を付与し、光学的に一括的に測定される、接合部を含む視野領域(IA)において、第1管部材の振動分布と、貫通孔を通して測定される第2管部材の振動分布とを、接合体の周方向の位置が異なる複数の視野領域について取得する。この振動分布により接合部全体における接合の良否を判定する。
