Welding - Quality requirements for heat treatment in connection with welding and allied processes (ISO 17663:2023)

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.

Schweißen - Qualitätsanforderungen zur Wärmebehandlung beim Schweißen und bei verwandten Prozessen (ISO 17663:2023)

Dieses Dokument stellt Qualitätsanforderungen für die Wärmebehandlung in Luft oder überwachten Atmosphären bereit, die in Werkstätten und auf Baustellen in Verbindung mit Schweiß  und Umformarbeiten durchgeführt wird. Es ist hauptsächlich für ferritische Stähle anwendbar, kann jedoch auch für andere Werkstoffe angewendet werden, sofern zutreffend.
Dieses Dokument stellt Herstellern, die Wärmebehandlungen durchführen oder wärmebehandelte Produkte oder Bauteile fertigen, einen Leitfaden zur Verfügung. Dieses Dokument kann auch als Grundlage für die Beurteilung des Herstellers hinsichtlich seiner Eignung zur Wärmebehandlung verwendet werden.
Auf das Erfüllen einer Anforderung kann verzichtet werden, wenn ein spezieller Prozess nicht für diese besondere Anforderung anwendbar ist. Dieses Dokument liefert einen flexiblen Rahmen für:
   besondere Anforderungen bei einer Wärmebehandlung durch den Hersteller, der ein Qualitätssystem nach ISO 9001 besitzt;
   besondere Anforderungen bei einer Wärmebehandlung durch den Hersteller, der ein anderes Qualitätssystem als das nach ISO 9001 besitzt;
   einen besonderen Leitfaden für einen Hersteller, der ein Qualitätskontrollsystem für die Wärme-behandlung entwickelt;
   einen besonderen Leitfaden zur Wärmenachbehandlung von Schweißungen durch Hersteller, die nach ISO 3834 2 oder ISO 3834 3 arbeiten;
   genaue Anforderungen für Spezifikationen, Regeln oder Produktnormen, die eine Kontrolle der Wärmebehandlungsaktivitäten fordern.

Soudage - Exigences de qualité relatives au traitement thermique associé au soudage et aux techniques connexes (ISO 17663:2023)

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.

Varjenje - Zahteve za kakovost pri toplotni obdelavi v povezavi z varjenjem in sorodnimi postopki (ISO 17663:2023)

Standard ISO 17663:2009 vsebuje zahteve za kakovost pri toplotni obdelavi v atmosferah z zrakom ali nadzorovanih atmosferah, ki se izvaja v delavnicah ali na mestu uporabe v povezavi z varjenjem in oblikovanjem. Uporablja se predvsem za feritna jekla, kjer je to ustrezno, pa ga je mogoče uporabiti za druge materiale.
Standard ISO 17663:2009 določa smernice za proizvajalce, ki izvajajo toplotno obdelavo ali izdelujejo toplotno obdelane proizvode ali sestavne dele. Uporabiti ga je mogoče tudi kot osnovo za ocenjevanje proizvajalca v povezavi z njegovo sposobnostjo toplotnega obdelovanja.
Standard je zasnovan kot prilagodljiv okvir za nadzor procesov toplotne obdelave. Izpolnitev zahteve je mogoče opustiti, če je mogoče utemeljiti, da se posamezna zahteva ne uporablja za določen proces.

3.1
manufacturer
person or organization responsible for heat treatment of products or components
3.2
loading temperature
temperature of the furnace at the stage when the product or component is put into the furnace
3.3
holding temperature
temperature at which the product or component is kept in order to achieve the specified properties
Note 1 to entry: The holding temperature depends on the type of heat treatment, type of material and material
thickness.
Note 2 to entry: Normally, the holding temperature is expressed as a temperature range.
3.4
holding time
time the product or component is kept at the holding temperature
Note 1 to entry: The holding time starts when the temperature at all measuring points has reached the minimum
value of the range of the holding temperature and stops when one of the measuring points falls below that
temperature.
Note 2 to entry: The holding time depends on the type of heat treatment, material and material thickness.
3.5
unloading temperature
temperature of the product or component when it is taken out of a furnace or when the heat source is
removed or switched off in any other heat treatment, e.g. local heat treatment
3.6
section temperature range
temperature range with a specified linear distance that can vary between two adjacent measuring
points
4 Review of requirements and technical review
4.1 General
The manufacturer shall review the contractual requirements and any other requirements together
with any technical data. This is to ensure that all information necessary to carry out the heat treatment
operations is available prior to the commencement of the work. The manufacturer shall affirm its
capability to meet all requirements and ensure adequate planning of all quality-related activities.
The review of requirements is carried out by the manufacturer to verify that the work content is within
its capability to perform, that sufficient resources are available to achieve delivery schedules and that
documentation is clear and unambiguous. The manufacturer shall ensure that variations between the
contract and previous quotation are identified.
4.2 Review of requirements
Aspects for consideration shall include the following:
a) product standard used, together with any supplementary requirements;
b) statutory and regulatory requirements;
c) any additional requirement determined by the manufacturer;
