介绍了螺旋缝埋弧焊管检测用定向X射线检测系统检验辐射场的构成，以及实际检验中需要调整DR检测系统的机构，如探臂、射线管头、平板探测器等的调整。重点介绍了定向X射线检测系统检验辐射场的两种调校方法，即螺栓校准和辐射场校准器校准，分析了两种调校方法的优缺点。以自主设计的辐射场校准器调校方法为例，通过对φ325 mm×8 mm焊管进行辐射场差异模拟试验，得到了不正确调校辐射场对焊偏检验结果有一定影响的结论。
介紹瞭螺鏇縫埋弧銲管檢測用定嚮X射線檢測繫統檢驗輻射場的構成，以及實際檢驗中需要調整DR檢測繫統的機構，如探臂、射線管頭、平闆探測器等的調整。重點介紹瞭定嚮X射線檢測繫統檢驗輻射場的兩種調校方法，即螺栓校準和輻射場校準器校準，分析瞭兩種調校方法的優缺點。以自主設計的輻射場校準器調校方法為例，通過對φ325 mm×8 mm銲管進行輻射場差異模擬試驗，得到瞭不正確調校輻射場對銲偏檢驗結果有一定影響的結論。

In this article, it briefly introduced the structure of inspection radiation field for directional X-ray inspection system used in SAWH pipe, and some organizations need to adjust DR inspection system, such as exploring arm, tube head, flat panel detector etc. It emphasized 2 adjustment and calibration methods for directional X-ray inspection system, the bolt calibration and radiation field calibrator, and analyzed advantages and disadvantages for the above two methods. Taking independent design radiation field calibrator calibration method as sample, through radiation field difference simulation test for φ325 mm ×8 mm welded pipe, it is concluded that incorrect calibration radiation field has certain influence on misalignment inspection result.
