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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 3834-2 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 10, Unification of requirements in the field of metal welding.
This second edition cancels and replaces the first edition (ISO 3834-2:1994), which has been technically
revised.

This part of ISO 3834 defines comprehensive quality requirements for fusion welding of metallic materials both
in workshops and at field installation sites.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 3834-1, Quality requirements for fusion welding of metallic materials — Part 1: Criteria for the selection
of the appropriate level of quality requirements
ISO 3834-5:2005, Quality requirements for fusion welding of metallic materials — Part 5: Documents with
which it is necessary to conform to claim conformity to the quality requirements of ISO 3834-2, ISO 3834-3 or
ISO 3834-4
In order to fulfil the quality requirements given in this part of ISO 3834, the conformity to relevant documents
given in ISO 3834-5 shall be verified.
In certain situations, e.g. where manufacturing is more suited to ISO 3834-3 or ISO 3834-4, or where
particular operations, such as heat treatment, are not undertaken, the requirements detailed in this part of
ISO 3834 may be selectively amended or deleted.
Otherwise, the requirements contained within this part of ISO 3834 shall be adopted in full.
5.1 General
The manufacturer shall review the contractual requirements and any other requirements, together with any
technical data provided by the purchaser or in-house data when the construction is designed by the
manufacturer. The manufacturer shall establish that all information necessary to carry out the manufacturing
operations is complete and available prior to the commencement of the work. The manufacturer shall affirm
its capability to meet all requirements and shall 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 any variations between the
contract and any previous quotation are identified and the purchaser notified of any programme, cost or
engineering changes that may result.
Items in 5.2 are typically considered at or before the time of the review of requirements review. Items in 5.3
usually form part of the technical review and are considered during the initial planning stage.
When a contract does not exist, e.g. items made for stock, the manufacturer is required to take into
consideration the requirements of 5.2 while carrying out the technical review (see 5.3).
c) location, accessibility and sequence of welds, including accessibility for inspection and for non-destructive
testing;
j) sub-contracting;
l) other welding requirements, e.g. batch testing of consumables, ferrite content of weld metal, ageing,
hydrogen content, permanent backing, use of peening, surface finish, weld profile;
m) use of special methods (e.g. to achieve full penetration without backing when welded from one side only);
p) environmental conditions relevant to the application of the process (e.g. very low-temperature ambient
conditions or any necessity to provide protection against adverse weather conditions);
q) handling of non-conformances.
6 Sub-contracting
When a manufacturer intends to use sub-contracted services or activities (e.g. welding, inspection, non-
destructive testing, heat treatment), information necessary to meet applicable requirements shall be supplied
by the manufacturer to the sub-contractor. The sub-contractor shall provide such records and documentation
of his work as may be specified by the manufacturer.
A sub-contractor shall work under the order and responsibility of the manufacturer and shall fully comply with
the relevant requirements of this part of ISO 3834. The manufacturer shall ensure that the sub-contractor can
comply with the quality requirements as specified.
The information to be provided by the manufacturer to the sub-contractor shall include all relevant data from
the review of requirements (see 5.2) and the technical review (see 5.3). Additional requirements may be
specified as necessary to assure sub-contractor compliance with technical requirements.
