摘要
根据GB 332 3- 87《钢熔化焊对接接头射线照相和质量分级》标准 ,结合现场实践 ,对目前国内小口径管对接焊缝X射线探伤中两种双壁双投影倾斜透照方法进行介绍 。
The two domestic double-wall double-projection inclined X-ray radiographic techniques for examination of butt weld of small bore pipes are introduced in accordance with GB 3323-87,Radiographic Examination and Quality Rating for Steel Melted Butt Weld Joints,and field practices.The determination of process parameters for parallel movement radiographic method is specially discussed.
