Abstract

PURPOSE: To improve the accuracy of the detection of welding defects, by expanding an end portion of an electro seamed tube in a fixed quantity, by recovering a portion where the end portion is extended and worked to an original form, and by inspecting a welding portion of the working portion in a non-destructive test.
CONSTITUTION: An electro seamed tube 6 cut in product length to be worked is expansion-worked and correction-worked in such a manner that an end portion of the tube 6 is inserted between a punch 1 and a die 2 under a condition that the tube is held by means of a proper clamp mold. The electro seamed tube 6 is drawn out from a portion between the punch 1 and the die 2, and a portion where the electro seamed tube 6 is extended is recovered to an original form. A welding portion of the end portion of the electro-unite tube 6 is inspected by means of an ultrasonic-wave flaw detection method, etc.
