Zusammenfassung:	Provided is a manufacturing method for an outer joint member (11, 11 2 ) of a constant velocity universal joint (10, 10 2 ), the outer joint member (11, 11 2 ) including: a cup section (12, 12 2 ) having track grooves (30, 30 2 ) formed in an inner periphery of the cup section (12, 12 2 ), which are engageable with torque transmitting elements (19, 23, 41); and a shaft section (13) formed at a bottom portion of the cup section (12, 12 2 ), the outer joint member (11, 11 2 ) being constructed by forming the cup section (12, 12 2 ) and the shaft section (13) as separate members, and by welding a cup member (12a, 12a 2 ) forming the cup section (12, 12 2 ) and a shaft member (13a) forming the shaft section (13) to each other, the manufacturing method at least including: a welding step (S6) of welding the cup member (12a, 12a 2 ) and the shaft member (13a) by irradiating a beam to joining end portions of the cup member (12a, 12a 2 ) and the shaft member (13a); and an ultrasonic flaw detection-inspection step (S6k) of inspecting a welded portion (49) formed in the welding step by a plurality of ultrasonic flaw detection methods with one probe (160).
