摘要
目前,锅炉生产行业的绝大多数企业都使用X射线电视实时成像系统检测小口径管子对接环焊缝。作为大批量管子焊接质量检测的有效手段,该方法在生产中具有不可替代的作用。但X射线电视实时成像系统采用图像增强器作为射线接收装置,具有体积大、射线转化效率低、易老化、图像噪声大、灵敏度低及设备使用成本高等弊端。成功开发了扫描式X射线成像器和动态图像处理系统,有效解决了上述难题。介绍了扫描式X射线成像器和动态图像处理系统的技术特点,并对扫描式X射线成像器与图像增强器进行了对比,分析了扫描式X射线成像器在锅炉生产行业应用的经济性。
Most of boiler manufacturers test butt welding seam for small bore pipe by using X-ray real-time radioscopy imaging system.For the batch pipe welding seam quality test methods,this is irreplaceable.The system use imagine intensifier as ray receiver device,which has some disadvantages,such as big volume and low ray conversion efficiency and easily aging,and big imaging noise,blur,low sensitivity,high equipment usage cost.Aiming at the problems of existing equipment,a scanning X-ray imager and dynamic imaging system was developed,and the above problems were solved for traditional test methods.
