Abstract

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.
