ISO 15614-8:2016规定了通过手动、部分机械化、全机械化或自动工艺对金属材料中管-管-板接头进行电弧焊接的焊接工艺评定试验的要求。 ISO 15614-8:2016是一系列标准的一部分。ISO 15607附录A中给出了该系列的详细信息。 通过管-管-板接头试验进行的资格鉴定可用于所有接头，即使它们是满载的或仅按照应用标准的要求进行密封焊接。 ISO 15614-8:2016适用于管与管板接头的金属材料熔焊，管与管板之间留有一定长度的管板厚度间隙。ISO 15614的本部分不适用于带有焊接管（外/内孔焊缝）锻造端部连接的管板。 对于承受载荷的机械膨胀管与管板接头的焊接，应规定焊接工艺试验。 对于其他应用和/或要求，如果规范要求，可以使用ISO 15614的本部分。 焊接工艺试验中应考虑补焊。

ISO 15614-8:2016 specifies requirements for the qualification testing of welding procedures for the arc welding of tube to tube-plate joints in metallic materials by manual, partly mechanized, fully mechanized, or automatic processes. ISO 15614-8:2016 is a part of a series of standards. Details of this series are given in ISO 15607, Annex A. Qualification by tube to tube-plate joint tests can be used for all joints even if they are fully loaded or only seal welded as required in application standards. ISO 15614-8:2016 applies to fusion welding of metallic materials for tube to tube-plate joints with a remaining gap between the tube and the tube-plate for some length of the tube-plate thickness. This part of ISO 15614 does not apply to tube-sheets with forged end connections with welded tubes (external/internal bore welds). For welding of tube to tube-plate joints with mechanical expansion which is load bearing, welding procedure test is to be defined. For other applications and/or requirements, this part of ISO 15614 can be used if required by the specification. Repair welding is to be considered in the welding procedure test.
