Welding — Quality requirements for heat treatment in connection with welding and allied processes

This document provides quality requirements for heat treatment in air or controlled atmospheres carried out in workshops and on site in connection with welding and forming. It applies mainly to ferritic steels but can be used for other materials as appropriate. This document provides guidance for manufacturers that perform heat treatment or produce heat-treated products or components. This document can also be used as a basis for assessing the manufacturer in respect to its heat treatment capability. The fulfilment of a requirement can be waived where justification can be provided that a specific requirement is not applicable to a specific process. This document is intended to be a flexible framework to provide: — specific requirements for heat treatment by manufacturers in order to have a quality system in accordance with ISO 9001; — specific requirements for heat treatment in specifications which require the manufacturer to have a quality system other than ISO 9001; — specific guidance for a manufacturer developing a quality control system for heat treatment; — specific guidance for post-weld heat treatment for manufacturers adopting ISO 3834-2 or ISO 3834‑3; — detailed requirements for specifications, regulations or product standards that require control of heat treatment activities.

Soudage — Exigences de qualité relatives au traitement thermique associé au soudage et aux techniques connexes

Le présent document spécifie des exigences de qualité relatives au traitement thermique à l'air libre ou en atmosphères contrôlées, appliqué en atelier ou sur chantier en soudage et en formage. Ce traitement s'applique principalement aux aciers ferritiques, mais peut être utilisé pour d'autres matériaux, le cas échéant. Le présent document fournit des directives aux constructeurs et aux fabricants qui réalisent un traitement thermique ou qui fabriquent des produits ou des pièces traités thermiquement. Le présent document peut également servir de base pour évaluer la compétence d'un constructeur ou d'un fabricant dans le domaine du traitement thermique. La réalisation d'une exigence peut être écartée si la justification peut être fournie qu'une exigence spécifique ne s'applique pas à un traitement spécifique. Le présent document est censé être un cadre souple pour la maîtrise des traitements thermiques pour fournir: — des exigences spécifiques relatives au traitement thermique appliqué dans le cadre de spécifications exigeant que le constructeur ou le fabricant utilise un système qualité selon l'ISO 9001, — des exigences spécifiques relatives au traitement thermique appliqué dans le cadre de spécifications exigeant que le constructeur ou le fabricant utilise un système qualité autre que ceux décrits dans l'ISO 9001, — des directives pour un constructeur ou le fabricant développant un système qualité pour le traitement thermique, — des directives spécifiques relatives au traitement thermique après soudage pour les constructeurs ou les fabricants adoptant l'ISO 3834‑2 ou l'ISO 3834‑3, — des exigences détaillées pour des spécifications, réglementations ou normes produits qui demandent un contrôle des activités de traitement thermique.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the

1 Domaine d'application
Le présent document spécifie des exigences de qualité relatives au traitement thermique à l'air libre ou
en atmosphères contrôlées, appliqué en atelier ou sur chantier en soudage et en formage. Ce traitement
s'applique principalement aux aciers ferritiques, mais peut être utilisé pour d'autres matériaux, le cas
échéant.
Le présent document fournit des directives aux constructeurs et aux fabricants qui réalisent un
traitement thermique ou qui fabriquent des produits ou des pièces traités thermiquement. Le présent
document peut également servir de base pour évaluer la compétence d'un constructeur ou d'un
fabricant dans le domaine du traitement thermique.
La réalisation d'une exigence peut être écartée si la justification peut être fournie qu'une exigence
spécifique ne s'applique pas à un traitement spécifique. Le présent document est censé être un cadre
souple pour la maîtrise des traitements thermiques pour fournir:
— des exigences spécifiques relatives au traitement thermique appliqué dans le cadre de spécifications
exigeant que le constructeur ou le fabricant utilise un système qualité selon l'ISO 9001,
— des exigences spécifiques relatives au traitement thermique appliqué dans le cadre de spécifications
exigeant que le constructeur ou le fabricant utilise un système qualité autre que ceux décrits dans
l'ISO 9001,
— des directives pour un constructeur ou le fabricant développant un système qualité pour le
traitement thermique,
— des directives spécifiques relatives au traitement thermique après soudage pour les constructeurs
ou les fabricants adoptant l'ISO 3834-2 ou l'ISO 3834-3,
— des exigences détaillées pour des spécifications, réglementations ou normes produits qui demandent
un contrôle des activités de traitement thermique.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directiveswww.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 17663:20222023(E)

Welding — Quality requirements for heat treatment in connection
with welding and allied processes
1 Scope
This document provides quality requirements for heat treatment in air or controlled atmospheres carried
out in workshops and on site in connection with welding and forming. It applies mainly to ferritic steels
but can be used for other materials as appropriate.
This document provides guidance for manufacturers that perform heat treatment or produce heat-
treated products or components. This document can also be used as a basis for assessing the
manufacturer in respect to its heat treatment capability.
The fulfilment of a requirement can be waived where justification can be provided that a specific
requirement is not applicable to a specific process. This document is intended to be a flexible framework
to provide:
— specific requirements for heat treatment by manufacturers in order to have a quality system in
accordance with ISO 9001;
Formatted: Pattern: Clear
Formatted: Pattern: Clear
— specific requirements for heat treatment in specifications which require the manufacturer to have a
quality system other than ISO 9001;

— specific guidance for a manufacturer developing a quality control system for heat treatment;
— specific guidance for post-weld heat treatment for manufacturers adopting ISO 3834-2 or
