Abstract
An ultrasonic-welding apparatus, which can automatically achieve measurement of the face-deflection the work piece after welding and during the welding of work pieces, such as a reel for a magnetic tape. The ultrasonic-welding apparatus includes: a cradle, onto which two types of work pieces to be welded are mounted in piles, and which can rotate around an axis vertical to the welding surface of a workpiece to be welded; a welding horn, which carries out welding using ultrasonic vibration wherein the two work pieces are sandwiched by the cradle; and a transmission-type laser sensor which measures the fixed part of the work pieces, after welding, by the irradiation of laser light which runs parallel to the welding surface, wherein the workpieces are rotating on the cradle and the welding horn is apart from the work pieces.
