角接接头X射线检测方法探讨

摘要

After welding centrifuge rotor body and baseboard by connection , it turned to shape and formed circumferential corner joint.It needed to be 100% radiographic tested.Using method of X-ray source ectad in single welled transillumination , negative was particially black , because it was too closed to centrifuge rotor body .And it could not be fully tested.Using method of X-ray source inide in single welled transillumination , negative was paticially white , because it was too closed to centrifuge rotor body , it could not live up to 100% testing. Through ananization of rediographic testing ’s principle , using method of X-ray source inside in single welled transillumination , and adjusted the angle of incidence degree , it finally gained reasonable technology in rediographic testing , which solved the problem of corner joint radiographic testing in centrifuge rotor .%离心机筛篮的筛篮身与底板在连接部位经过焊接成型后，形成了环向角接接头，需要对其进行100％射线检测。采用源在外单壁透照方式，底片在靠近筛篮身部分过黑，不能实现100％检测；采用源在内单壁透照方式，底片在靠近筛篮身部分过白，亦不能实现100％检测。通过对射线检测原理分析，采用源在内单壁透照方式，调整入射角度，最终得到合理的射线检测工艺，解决了离心机筛篮角接接头射线检测的问题。
