Abstract:
A manufacturing method is used for an outer joint member of a constant velocity universal joint. The outer joint member includes a cup section having track grooves formed in its inner periphery, which are engageable with torque transmitting elements, and a shaft section formed at a bottom portion of the cup section. The manufacturing method includes welding the cup and shaft members by irradiating a beam to joining end portions of the cup and shaft members, causing an outer surface including the welded portion to be formed into a flat smooth surface by removal processing, irradiating ultrasonic waves to the flat smooth surface with one probe at an incident angle which prevents total reflection in a circumferential angle beam flaw detection method, and setting a focal point of the ultrasonic waves to positions from a surface to an inside of the welded portion, to thereby perform inspection.

Claim (Index 8):
An ultrasonic flaw defection-inspection method for a welded portion of an outer joint member of a constant velocity universal joint,\n the outer joint member comprising:\n a cup section having track grooves formed in an inner periphery of the cup section, which are engageable with torque transmitting elements; and \n a shaft section formed at a bottom portion of the cup section, \n the outer joint member being constructed by forming the cup section and the shaft section as separate members, and by welding a cup member forming the cup section and a shaft member forming the shaft section to each other, the ultrasonic flaw detection-inspection method comprising: forming an outer surface including the welded portion into a flat smooth surface by removal processing; irradiating ultrasonic waves to the flat smooth surface with one probe at an incident angle which prevents total reflection of the ultrasonic waves in a circumferential angle beam flaw detection method; and setting a focal point of the ultrasonic waves of the probe to a plurality of positions within a thickness of the welded portion, to thereby perform inspection.
