| description | The invention belongs to the field of defects control of friction stir welding and particularly discloses a method and equipment for measuring friction stir welding holes. The equipment comprises a detection module and a calculation module which are mutually connected, wherein the detection module is used for acquiring an image and temperature of an actual weld joint and determining whether holes exist by making comparison on the results of the temperatures according to temperature data of a singular point of finite element calculation. According to the method and equipment, the online detection of holes of the welding joints can be realized, and the positions of the holes can be determined, so that the welding scheme can be amended, and the holes of the welding joints can be controlled.
本发明属于搅拌摩擦焊接缺陷控制领域，具体公开了种搅拌摩擦焊孔洞测量方法及设备，测量设备包括相互连接的检测模块与计算模块；通过检测模块获得实际焊缝的图像与温度，并通过有限元计算奇异点的温度数据，通过比较二者的结果确定孔洞是否存在；本发明可以实现焊缝孔洞的在线检测，确定孔洞所在的位置，以便修改焊接方案，对焊缝孔洞予以控制。 |
