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 document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, Quality management in the field of welding, in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 121, Welding and allied processes, in accordance with
the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This document cancels and replaces ISO/TR 3834-6:2007, which has been technically revised.
The main changes are as follows:
— document changed from a Technical Report to an International Standard;
— references to IIW and IAB removed;
— Clause 11 updated to address visual testing of welds;
— text aligned with ISO 14731.
A list of all parts in the ISO 3834 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s

Welding is a special process in that it is not always possible to verify the final result 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. The ISO 3834 series deals with quality
requirements in welding and has been prepared in order to identify those controls and procedures.
The ISO 3834 series 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, the ISO 3834 series can be
used independently of ISO 9001.
The ISO 3834 series 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.
One of the aims of the ISO 3834 series is to specify 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 the ISO 3834
series 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
The ISO 3834 series does not in itself require external assessment or certification. However, assessments
by customers and certification by independent bodies are growing trends in commercial
