Abstract

Sposób kontroli jakości połączeń elementów o kołowym przekroju zgrzanych doczołowe łukiem wirującym, zwłaszcza połączeń cienkościennych elementów rurowych w postaci półosi i wałów napędowych z końcówkami roboczymi w postaci wałów krótkich czy przegubów, w którym ocenę jakościową połączenia dokonuje się na podstawie analizy fali ultradźwiękowej którą na czas pomiaru w kierunku zgrzeiny wysyła się z głowicy ultradźwiękowej (7) charakteryzuje się tym, że zgrzane łukiem wirującym elementy (1, 2) przy użyciu rolek (3), pozycjonuje się, a następnie na czas pomiaru wprawia się w ruch obrotowy w zakresie co najmniej pełnego kąta, przy czym podczas pomiaru kierowaną na zgrzeinę falę ultradźwiękową sprzęga się z kierowanym na zgrzeinę strumieniem cieczy, którą na zgrzeinę natryskuje się przy użyciu dyszy (6), w której umieszcza się głowicę ultradźwiękową (7) generującą falę podpowierzchniową w ściance zgrzanych elementów (1, 2).A method of checking the quality of connections of circular cross-section welded butt welded joints, especially connections of thin-walled tubular elements in the form of half shafts and drive shafts with working ends in the form of short shafts or joints, in which the qualitative assessment of the connection is made on the basis of ultrasonic wave analysis, which for the time of measurement in the direction of the weld, it is sent from the ultrasonic head (7) characterized by the fact that the elements (1, 2) welded with a rotating arc using rollers (3) are positioned, and then at the time of measurement set in rotational motion in the range of at least full angle, while during the measurement the ultrasonic wave directed at the weld is coupled with the stream of liquid directed at the weld, which is sprayed onto the weld using a nozzle (6) in which an ultrasonic head (7) is placed generating a subsurface wave in the wall of welded elements tes (1, 2).
