According to the hull weld flaw detection imaging identification method and the information processing method, equipment is arranged between a radiation source and an imaging screen, a proper distance and photon release amount are formed between the radiation source and the imaging screen, and a designed identification method or information processing is adopted, so that the relation value of the signal-to-noise ratio and the pulse number under different distances of the radiation source and the imaging screen is obtained; therefore, optimal solutions of different imaging distances and X-ray frequencies are obtained, and effective and precise flaw detection identification of different ship body weld joints is realized. And accurate detection, identification and positioning are realized according to materials, densities and thicknesses of different parts of different welding workpieces.
本发明公开了一种船体焊缝探伤成像识别方法及信息处理方法,通过设备在射线源和成像屏设置,之间形成合适的距离和光子释放量,采用设计的识别方法或信息处理,从而得到射线源和成像屏不同距离下信噪比和脉冲数的关系值,从而得到了不同成像距离和X射线频率的最优解,以实现对不同船体焊缝有效、精密探伤识别。且实现根据不同焊接工件不同部位的材料、密度和厚度,实现精确探测识别、定位。
