Abstract
Ultrasonically welded thermoplastic materials are nondestructively inspected by sensing the infrared radiation emitted from the weld region of the material during or immediately subsequent to the welding operation. The sensed radiation levels are compared with a predetermined value and if they exceed the predetermined value are indicative of an acceptable weld. If the sensed radiation peak does not exceed the predetermined level, the weld is deemed to be unacceptable.
