标准范围

本欧洲标准规定了通过手动、部分机械化、机械化或自动工艺对金属材料管-管-板接头进行电弧焊接的焊接工艺评定试验的要求。本标准是一系列标准的一部分。prEN 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。在这种情况下，应制作一个或多个特殊试样，以模拟生产接头的所有基本特征，例如:。g、 尺寸、约束、散热效果。试验应在生产前和生产条件下进行。本标准适用于带间隙的管-管板接头用金属材料的熔焊。本标准不适用于带有焊接管（外/内孔焊缝）的锻造端部连接的管板。对于无间隙的管与管板接头的焊接，规范中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，可使用本标准。焊接工艺试验中应考虑补焊。

This European Standard 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, mechanized or automatic processes.This standard is a part of a series of standards. Details of this series are given in prEN 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.In such cases, one or more special test pieces should be made to simulate the production joint in all essential features, e.g. dimensions, restraint, heat sink effects. The test should be carried out prior to and under the conditions to be used in production.This standard applies to fusion welding of metallic materials for tube to tube-plate joints with gap. This standard 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 without gap welding procedure test should be defined in the specification.For other applications and/or requirements the standard can be used if required by the specification.Repair welding should be considered in the welding procedure test.
