摘　　要：用焊接方法建造的ASME规范产品,其焊接接头系数与焊接接头的无损检测程度密切相关。在ASME规范压力容器卷中明确规定了焊接接头系数选取规则,但在一些较为复杂的情况下却很容易引起误解而选错系数。通过详细分析ASME规范中关于RT标记的要求和应用,探讨在实际应用中如何根据产品的RT标记来确定焊接接头系数。The joint coefficient of the ASME specified product constructed by welding is closely related to the non-destructive testing degree of the joint. The ASME-Ⅷ code （ rules for construction of pressure vessels） specifically defines the selection criterion of the joint coefficient. However, the criterion is misleading in some complex situations, resulting in mistakes in coefficient selection. Discusses how to determine the joint coefficient according to RT markings for ASME specified products during actual construction by analyzing the requirements and applications of RT markings.
