    • This invention provides a method for inspecting a joined region and joining strength of a joined object formed by a spot friction stir joining process. In this method, an ultrasonic wave is introduced into the joined object from a backing face 25 opposed to a joining tool plunging face 24 and the ultrasonic wave reflected from the joined object 20 is taken in. In this case, the joining region 21 and the joining strength is estimated by observing a reflected wave of the ultrasonic wave in the vicinity of a position, along a reference direction Z, corresponding to an interface 27 of two joining members, without using the reflected wave of the ultrasonic wave reflected from the joining tool plunging face, thereby inspecting the joined object based on the estimation result. Thus, influence of a concave/convex shape of a joining mark 29 formed in the joining tool plunging face 24 can be avoided, and the use of the ultrasonic wave for estimating the joined region 21 can achieve an inspection of joining quality without destroying the joined object 20.
    • 本发明提供了一种用于检查接合区域的方法和通过点摩擦搅拌接合工艺形成的接合物体的接合强度。 在该方法中,从与接合工具插入面24相对的背衬面25将超声波引入到接合物中,并且从接合物20反射的超声波被吸入。在这种情况下,接合区域21和 通过在不使用从连接工具反射的超声波的反射波的情况下,在与两个接合部件的接口27对应的基准方向Z的位置附近观察超声波的反射波来估计接合强度 从而根据估计结果检查接合物体。 因此,可以避免形成在接合工具插入面24中的接合标记29的凹凸形状的影响,并且使用用于估计接合区域21的超声波可以实现接合质量的检查,而不会破坏接合 对象20。
