    • The intensity of first reflected ultrasonic waves reflected from an end of a first electrode tip is measured while the electrode tip is separated from a workpiece. The intensity of second reflected waves reflected from the end of the electrode tip is measured while the electrode tip contacts with the workpiece. Based on the above intensities, an intensity ratio (reflectance) and the fraction of the waves entering the workpiece are determined from the following equations: reflectance=(intensity of second reflected waves)/(intensity of first reflected waves) fraction of waves entering the workpiece=1−reflectance. From a predetermined correlative relationship between a contact area of a region enabling ultrasonic waves to be incident on the workpiece and the determined fraction of the entering waves, a ratio (contact area ratio) is determined between a total area of the region and a contact area of the region contacting with the workpiece.
    • 在将电极头与工件分离的同时测量从第一电极头的端部反射的第一反射超声波的强度。 在电极尖端与工件接触的同时测量从电极尖端的端部反射的第二反射波的强度。 基于上述强度,从以下等式确定强度比(反射率)和进入工件的波的分数:反射率=(第二反射波的强度)/(第一反射波的强度)进入的波的分数 工件= 1反射率。 根据能够使入射到工件上的超声波的区域的接触面积与所确定的入射波次数之间的预定的相关关系,在该区域的总面积和接触面积之间确定比率(接触面积比) 的区域与工件接触。

    • A spot welding inspecting apparatus is provided with: a gun chip; a signal transmitting part; an ultrasonic sensor; an inner cylinder; a through hole; a partitioning cylinder; a first flow path; a second flow path; and a third flow path.The inner cylinder is inserted to an outer cylinder of spot welding gun and holds the ultrasonic sensor. The through hole is provided on the inner cylinder. The partitioning cylinder surrounds the through hole and is inserted into a gap between the ultrasonic sensor and the outer cylinder. The first flow path is formed between the inner cylinder and the partitioning cylinder by passing the through hole from an inner portion of the inner cylinder. The second flow path is formed at the gun chip to be circulated around a front end of the partitioning cylinder. The third flow path is formed between the outer cylinder and the partitioning cylinder. A cooling agent flows in an order of the first flow path, the second flow path and the third flow path.
