This part of ISO 15614 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.
This part of ISO 15614 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.
This part of ISO 15614 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.

L'ISO 15614-8:2016 spécifie les exigences pour l'épreuve de qualification de modes opératoires pour le soudage à l'arc d'assemblages de tubes sur plaque tubulaire en matériaux métalliques avec des procédés manuels, semi-automatique, automatiques ou entièrement automatique.
L'ISO 15614-8:2016 fait partie d'une série de normes. Les détails sur cette série de normes sont donnés dans l'ISO 15607, Annexe A.
La qualification par des épreuves pour assemblages de tubes sur plaque tubulaire peut être utilisée pour tous les assemblages, même si ces derniers sont entièrement soumis à une charge ou s'ils comportent seulement des soudures d'étanchéité comme l'exigent les normes d'application.
L'ISO 15614-8:2016 s'applique au soudage par fusion des matériaux métalliques pour les assemblages de tubes sur plaque tubulaire avec jeu subsistant après soudage entre le tube et la plaque tubulaire sur une certaine longueur de l'épaisseur de la plaque tubulaire. L'ISO 15614-8:2016 ne s'applique pas aux assemblages tubes sur plaque avec raccordements forgés sur des tubes soudés (soudures sur alésage intérieur/extérieur).
Pour la réalisation d'assemblages de tubes sur plaque tubulaire suivis d'une expansion mécanique résistante de tube, l'épreuve de qualification du mode opératoire de soudage doit être définie.
Pour d'autres applications et d'autres exigences, l'ISO 15614-8:2016 peut être utilisée si cela est prévu dans la spécification.
La réparation par soudage doit être incluse dans l'épreuve de qualification du mode opératoire de soudage.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

DRAFT INTERNATIONAL STANDARD ISO/DIS 15614-8

Specification and qualification of welding procedures for
metallic materials — Welding procedure test — Part 8: Welding
of tube to tube-plate joints
1 Scope
This International 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, mechanized or automatic processes.
This standard 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.
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 a gap between
the tube and the tube plate for some length of the tube plate thickness. 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 with mechanical expansion which is load bearing 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.
