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

Introduction
Welding is a special process in that the final result may not be able to be verified by testing. The quality
of the weld is manufactured into the product, not inspected. This means that welding normally requires
continuous control or that specific procedures be followed, or both. ISO 3834 deals with quality
requirements in welding and has been prepared in order to identify those controls and procedures.
ISO 3834 is not a quality system standard intended to take the place of ISO 9001, but a useful, additional
tool for use when ISO 9001 is applied by manufacturers, in which case the meeting of its requirements
needs to be recorded in certificates or documentation. However, ISO 3834 can be used independently of
ISO 9001.
ISO 3834 is intended for the fusion welding of metallic materials, and its application is independent
of the products manufactured. However, its principles and many of its detailed requirements are also
relevant for other welding and welding-related processes.
Among other International Standards covering resistance welding and thermal spraying are ISO 14554
and ISO 14922, respectively.
One of the aims of ISO 3834 is to define requirements in the field of welding so that contracting parties
or regulators do not have to do this themselves. A reference to a particular part of ISO 3834 should be
sufficient to demonstrate the capabilities of the manufacturer to control welding activities for the type
of work being done. This concept also applies to committees responsible for drafting product standards.
ISO 3834 does not in itself require external assessment or certification. However, assessments by
customers and certification by independent bodies are growing trends in commercial relations and the
standard can serve as a basis for these purposes, as well as for the demonstration of performance by
those manufacturers implementing it.

5 Using ISO 3834
5.1 General
ISO 3834-1 provides criteria for the selection and use of ISO 3834 as a whole. The following subclauses
identify different ways whereby the manufacturer may select or be required to adopt ISO 3834.
5.2 Product standards
Where product standards require control of fusion welding, ISO 3834 should be used to organize those
welding activities.
5.3 Purchasers and users
Purchasers and users of welded products may specify in contract documents that manufacturers
demonstrate their competence by compliance with ISO 3834.
5.4 Quality management systems in accordance with ISO 9001
Since ISO 9001 does not include specific requirements for welding activities, ISO 3834-2, ISO 3834-3
and ISO 3834-4 should be used.
5.5 Quality management systems other than ISO 9001
For welding activities in quality management systems other than ISO 9001 that do not include specific
requirements for welding activities, ISO 3834-2, ISO 3834-3 and ISO 3834-4 should be used.
5.6 Manufacturers
Whenever manufacturers wish to give evidence of their competence in fusion welding activities, the
appropriate part of ISO 3834 should be used.
6 Incorporating ISO 3834 in product standards
An important group of users of ISO 3834 is the committees that draft product standards at the
international, regional and national levels. ISO 3834-2, ISO 3834-3 and ISO 3834-4 provide a range of
quality requirements for welding. Committees drafting product standards are encouraged to select a
part, or parts, of ISO 3834 that provide the appropriate quality requirements for the products to be
manufactured, taking account of the selection criteria given in ISO 3834-1. Each part of ISO 3834 is
designed to provide a complete set of quality requirements; additional requirements should not need to
be specified unless very compelling reasons exist. In case of doubt, or where additional requirements
are being considered, consultation with ISO/TC 44/SC 10 is recommended.
Where welding is involved in the manufacture of a product, the standards committee may define
the documents to be applied or else take them from the ISO documents specified in ISO 3834-5. The
committee should also select the appropriate quality requirement standard or standards to be
applied. Where a series of levels exist in the ISO documents in ISO 3834-5, e.g. for welding procedure
qualification, it would be satisfactory for the standardization committee to select only those that would

be acceptable. The development of tables linking parts of ISO 3834 (with or without other quality-
related standards such as ISO 9001) to requirements other than those given in ISO 3834, is strongly
discouraged.
7 Using other documents with ISO 3834
Full conformity with ISO 3834-2, ISO 3834-3 and ISO 3834-4 may be achieved either by adopting the
ISO documents in accordance with ISO 3834-5, or applying other standards that provide equivalent
technical conditions.
Standards that do not provide equivalent conditions may be adopted if they are referenced in product
standards that are used in full by the manufacturer.
Product standards that have been operated satisfactorily in service may be considered by a manufacturer
as being recognized for application with ISO 3834. Where a manufacturer bases his demonstration of
conformity to ISO 3834 on product standards, it is the responsibility of the manufacturer to apply the
corresponding standards — whether separately specified or incorporated in the product standard
— in their totality. It is the responsibility of the manufacturer to demonstrate technically equivalent
conditions when standards other than the ISO documents in accordance with ISO 3834-5 are applied.
Certificates issued following assessment by independent certification organizations or claims of
compliance by a manufacturer with any part of ISO 3834 should clearly identify the documents used by
the manufacturer and provide or reference evidence of technical equivalence as applicable.
8 Documentation and quality systems
8.1 Documentation
In any control system there is a need for documentation. The term documentation embraces a range of
different types of documents such as procedures, records, instructions and certificates (see Table 1).
ISO 3834-2, ISO 3834-3 and ISO 3834-4 require certain documents to be produced. Annex A gives
examples of the types of documents which may be used by manufacturers.

8.2 Quality management system
ISO 3834 does not specifically require a quality management system. However, ISO 3834-1 identifies
those elements that could be considered as complementing ISO 3834 if a quality management system
were to be adopted. Of these, a most important one is document control, and manufacturers are
expected to implement a document control procedure ensuring that
a) documents are maintained up to date,
b) those in receipt of documents are identified,
c) the latest issues of the documents are available at locations where they are used,
d) obsolete documents are withdrawn,
e) records are archived to avoid deterioration and to enable retrieval, and
f) records are not destroyed without authorization.
Some of the records generated as part of this system require updating at periodic intervals. These
include calibration/validation records and welder qualification records.
Manufacturers who operate a quality management system conforming to ISO 9001 are expected to
have a documented system in place covering those elements identified in ISO 3834-1.
The effectiveness of the welding control system will depend to a large extent on the management input
and their role in monitoring performance and implementing action when weaknesses are detected.
Applying management review and internal audit ensures top management involvement in the welding
control system and enables the monitoring of performance and introduction of measures to overcome
identified deficiencies. Figure 1 provides a summary of critical measures in the welding control system
to assist management review of the performance of the welding control system.

9 Selecting the level of quality requirements
ISO 3834 incorporates three levels of quality requirements that may be included in product standards,
regulations and contracts or selected by a manufacturer. The level selected will depend on the nature of
the product being manufactured, the conditions under which it is to be used and the range of products
manufactured. In ISO 3834-1, it is stated that the standard can be applied in a variety of industrial
situations. The following criteria are identified as being those applying in the selection of the most
suitable level:
1) the extent and significance of safety critical products;
2) the complexity of manufacture;
3) the range of products manufactured;
4) the range of different materials used;
5) the extent to which metallurgical problems can occur;
6) the extent to which fabrication imperfections (e.g. misalignment, distortion, weld imperfections)
affect product performance.
Product standards that require compliance with ISO 3834 emphasize two critical areas in the choice
of the level of quality requirements: the safety-critical nature of the products and the significance of
dynamic loading in the product service environment.
In general, the standard level of quality requirements should be suitable for the broad range of
products having a normal safety critical component and that could experience dynamic loading. Such
products would be manufactured from conventional materials where the weldability is known and the
precautions to be taken to ensure mechanical performance and defect-avoidance are well documented.
Products having a very limited safety component and that are subjected to only moderate static
loads with minor dynamic components would normally only require the elementary level of quality
requirements.
Where there are significant safety factors with high static and dynamic loadings and the materials are
designed for high performance applications, the comprehensive level of quality requirements would be
appropriate. However, there may be situations where, because of the innovative nature of the design or
the use of novel production processes, the comprehensive level of quality requirements is selected in
place of the standard level.
