Abstract

Procédé pour l'examen par ultrasons de tubes ou de barres défilant lineairement, au moyen d'une installation comportant des têtes d'examen fixes, en particulier pour des tubes de diamètre extérieur allant jusqu'à 100 mm. Selon l'invention, ce procédé est caractérisé en ce que le produit à examiner est simultanément irradié par des sources ultrasonores qui sont réparties sur toute la totalité dudit produit et dont les faisceaux se rencontrent, en ce que les résu tats d'examen des différentes sources ultrasonores sont exploités séparément les uns des autres et en ce que de même les indications de défaut sont effectuées séparément Examen de produits sidérurgiques par ultrasons.Process for the ultrasonic examination of tubes or bars moving linearly, by means of an installation comprising fixed examination heads, in particular for tubes with an external diameter of up to 100 mm. According to the invention, this method is characterized in that the product to be examined is simultaneously irradiated by ultrasonic sources which are distributed over the whole of said product and the beams of which meet, in that the results of examination of the different Ultrasonic sources are operated separately from each other and in that likewise fault indications are carried out separately Examination of steel products by ultrasound.
