Quality requirements for fusion welding of metallic materials - Part 1: Criteria for the selection of the appropriate level of quality requirements (ISO 3834-1:2021)
This document specifies a general outline of the ISO 3834 series and criteria to be taken into account for
the selection of the appropriate level of quality requirements for fusion welding of metallic materials,
among the three levels specified in ISO 3834-2, ISO 3834-3 and ISO 3834-4.
It is applicable to manufacturing, both in workshops and at field installation sites.
This document does not specify requirements for a total quality management system (QMS). However,
Clause 6 identifies QMS elements where their inclusion complements the ISO 3834 series.
Qualitätsanforderungen für das Schmelzschweißen von metallischen Werkstoffen - Teil 1: Kriterien für die Auswahl der geeigneten Stufe der Qualitätsanforderungen (ISO 3834-1:2021)
Dieses Dokument beschreibt die allgemeine Auslegung der Normenreihe ISO 3834 und die zu beachtenden Kriterien für die Auswahl der geeigneten Stufe der Qualitätsanforderungen für das Schmelzschweißen von metallischen Werkstoffen, aus den drei festgelegten Stufen in ISO 3834-2[1], ISO 3834-3[2] und ISO 3834-4[3]. Es gilt für die Herstellung, sowohl in Werkstätten als auch auf Baustellen.
ANMERKUNG 1 ISO 3834-2, ISO 3834-3 und ISO 3834-4 enthalten komplette Sätze von Qualitätsanforderungen zur Prozesskontrolle für alle Schmelzschweißprozesse (für einen einzelnen Prozess oder in einer festgelegten Kombination). ISO 3834-5 legt die Dokumente fest, deren Anforderungen erfüllt werden müssen, um die Übereinstimmung mit den Qualitätsanforderungen nach ISO 3834-2, ISO 3834-3 oder ISO 3834-4 nachzuweisen.
Dieses Dokument legt keine Anforderungen für ein Qualitätsmanagementsystem fest. Aber Abschnitt 6 enthält Elemente eines Qualitätsmanagementsystems, deren Einschluss ISO 3834 ergänzt.
ANMERKUNG 2 ISO 3834-2, ISO 3834-3 und ISO 3834-4 dürfen für sich allein oder in Verbindung mit ISO 9001:2015 vom Hersteller angewendet werden.
Exigences de qualité en soudage par fusion des matériaux métalliques - Partie 1: Critères pour la sélection du niveau approprié d'exigences de qualité (ISO 3834-1:2021)
Le présent document fournit un aperçu général de série ISO 3834 et les critères à prendre en compte pour la sélection d'un niveau approprié d'exigences de qualité en soudage par fusion des matériaux métalliques, parmi les trois niveaux spécifiés dans l'ISO 3834-2, l'ISO 3834-3 et l'ISO 3834-4.
Il est applicable pour la fabrication aussi bien en atelier que sur les sites de montage.
Le présent document ne spécifie pas d'exigences relatives à un système complet de management de la qualité (SMQ). Cependant, l'Article 6 identifie les éléments d'un SMQ dont la prise en compte vient compléter l'ISO 3834.

Introduction
Processes such as fusion welding are widely used to manufacture many products. In some companies,
they are the key feature of production. Products can range from simple to complex. Examples include
pressure vessels, domestic and agricultural equipment, cranes, bridges, transport vehicles and other
items.
These processes exert a profound influence on the cost of manufacture and quality of the product.
Therefore, it is important to ensure that these processes are carried out in the most effective way and
that appropriate control is exercised over all aspects of the operation.
It is emphasized that the ISO 3834 series is not a quality management system (QMS) standard replacing
ISO 9001:2015. However, it can be a useful tool when ISO 9001:2015 is applied by manufacturers.
Specification of quality requirements for welding processes is important because the quality of these
processes cannot be readily or economically validated. Therefore, they are consi

Introduction
Processes such as fusion welding are widely used to manufacture many products. In some companies, they
are the key feature of production. Products may range from simple to complex. Examples include pressure
vessels, domestic and agricultural equipment, cranes, bridges, transport vehicles and other items.
These processes exert a profound influence on the cost of manufacture and quality of the product. It is
important, therefore, to ensure that these processes are carried out in the most effective way and that
appropriate control is exercised over all aspects of the operation.
It is emphasised that the ISO 3834 series is not a quality management system standard replacing
ISO 9001:2015. However, it can be a useful tool when ISO 9001:2015 is applied by manufacturers.
Specification of quality requirements for welding processes is important because the quality of these
processes cannot be readily or economically validated. Therefore, they are considered to be special
processes as noted by ISO 9000:2015.
Quality cannot be inspected into a product: quality has to be built in. Even the most extensive and
sophisticated non-destructive testing does not improve the quality of the product.
For products to be free from serious problems in production and in service, it is necessary to provide
controls, from the design phase, through material selection, into manufacture and subsequent
inspection. For example, poor design may create serious and costly difficulties in the workshop, on site,
or in service. Incorrect material selection may result in problems, such as cracking in welded joints.
To ensure sound and effective manufacturing, management needs to understand and appreciate the
sources of potential trouble and to implement appropriate procedures for their control.
The ISO 3834 series identifies measures that are applicable for different situations. Typically, they may
be applied in the following circumstances:
— in contractual situations: specification of welding quality requirements;
— by manufacturers: establishment and maintenance of welding quality requirements;
— by committees drafting manufacturing codes or application standards: specification of welding
quality requirements;
— by organizations assessing welding quality performance, e.g. third parties, customers, or
manufacturers.
The ISO 3834 series can be used by internal and external organizations, including certification
bodies, to assess the manufacturer's ability to meet customer, regulatory or the manufacturer's own
requirements.
