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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
