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.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
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/TR 581 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 7, Representation and terms.
It cancels and replaces ISO 581:1980, which has been technically revised.

TECHNICAL REPORT ISO/TR 581:2005(E)

Weldability — Metallic materials — General principles
1 Scope
This Technical Report gives general principles related to the weldability of metallic materials. These principles
apply to all welding processes and all different types of construction whatever properties they may have.
2 Weldability
2.1 General
A component consisting of metallic material is considered to be weldable by a given process when metallic
continuity can be obtained by welding using a suitable welding procedure. At the same time, the welds shall
comply with the requirements specified in regard to both their metallurgical and mechanical properties and
their influence on the construction of which they form a part. Weldability is governed by three factors, namely
material, design and production (see Figure 1).
Each of these factors is associated with different properties:
a) Metallurgical weldability: material properties
These are influenced primarily by production and to a minor extent by the design.
b) Cons
