Abstract

The accuracy and speed of examination to see whether a spot-welded portion is good or defective by means of an ultrasonic flaw detector are enhanced. An automatic ultrasonic examining device (1) comprises an ultrasonic flaw detector (2), a robot arm (4), and a controller (5). The ultrasonic flaw detector (2) has an ultrasonic probe (2a) for detecting transmitted and reflected ultrasonic waves by touching the ultrasonic probe (2a) to a spot-welded portion and an ultrasonic flaw detector body (2b) connected to the ultrasonic probe (2a) and adapted to convert a reflected wave detection signal received from the ultrasonic probe (2a) into flaw detection information. The controller (5) has actual center position computing means (54) for determining the actual center position of the spot-welded portion on the basis of the flaw detection information collected from around a preset temporary center position of the spot-welded portion and judging means (56) for judging from flaw detection information collected at the actual center position whether the spot-welded portion is good or defective.

Description

technical field [0001] The present invention relates to an automatic ultrasonic inspection device, its inspection method and a manufacturing method using the inspection method, in particular to an automatic ultrasonic inspection device using a robot, its inspection method and a manufacturing method using the inspection method. Background technique [0002] Conventionally, a method using an ultrasonic flaw detector has been known as a nondestructive inspection method for spot welds. The structure of an ultrasonic flaw detector includes, for example, an ultrasonic probe that contacts a spot weld to transmit ultrasonic waves and detect reflected waves, and an ultrasonic flaw detector that is connected to an ultrasonic probe and receives reflected wave detection signals from the ultrasonic probe and converts them into flaw detection data. device body. In this ultrasonic flaw detector, the attenuation of ultrasonic waves due to the nugget formed inside the spot weld can be used ...
