Specification and qualification of welding procedures for metallic materials — Welding procedure test — Part 8: Welding of tubes to tube-plate joints
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.
