APPARATUS AND METHOD FOR DETERMINING NON-DEFECTIVE OR DEFECTIVE OF WELDING OF WELDED MATERIAL

PROBLEM TO BE SOLVED: To rapidly determine non-defective or defective of welding by shortening a time required for the determination. SOLUTION: This apparatus comprises temperature sensors 14, 15a to 15c disposed at upstream and downstream of an ultrasonic welder 21 at a conveying route 12a to detec...

Summary:PROBLEM TO BE SOLVED: To rapidly determine non-defective or defective of welding by shortening a time required for the determination. SOLUTION: This apparatus comprises temperature sensors 14, 15a to 15c disposed at upstream and downstream of an ultrasonic welder 21 at a conveying route 12a to detect temperatures of the vicinity of a part to be welded before and after welding, and a determination control means 20 for obtaining a temperature difference of the vicinity of a part to be welded before and after welding based on measured temperatures from the sensors 14, 15a to 15c to determine non-defective or defective of the welding at the welded material.
