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 9692-1 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 7, Representation and terms.
This first edition of ISO 9692-1 cancels and replaces ISO 9692:1992 which has been technically revised.
ISO 9692 consists of the following parts, under the general title Welding and allied processes —
Recommendations for joint preparation:
 Part 1: Manual metal-arc welding, gas-shielded metal-arc welding, gas welding, TIG welding and beam
welding of steels
 Part 2: Submerged arc welding of steels
 Part 3: Metal inert gas welding and tungsten inert gas welding of aluminium and its alloys
 Part 4: Clad steels

Introduction
This part of ISO 9692 defines the parameters characterizing the joint preparation and the collection of
frequently recurring values and shapes.
The recommendations given in this part of ISO 9692 have been compiled on the basis of experience and
contain dimensions for types of joint preparation that are generally found to lead to suitable welding conditions.
However, the extended field of application makes it necessary to give a range of dimensions. The dimension
ranges specified represent design limits and are not tolerances for manufacturing purposes. Manufacturing
limits depend, for instance, on welding process, parent metal, welding position, quality level, etc. Because of
the common character of this part of ISO 9692, the examples given cannot be regarded as the only solution
for the selection of a joint type.
Specific fields of application and manufacturing requirements (e.g. pipeline construction) may be covered by
selected ranges specified in other standards adapted from this basic part of ISO 9692.
Request for an official interpretation of technical aspects of this part of ISO 9692 should be directed to the
relevant secretariat of ISO/TC 44/SC 7 via the user's national standardization body; a listing of these bodies
can be found at www.iso.org.

Welding and allied processes — Recommendations for joint
preparation —
Part 1:
Manual metal-arc welding, gas-shielded metal-arc welding, gas
welding, TIG welding and beam welding of steels
1 Scope
This part of ISO 9692 specifies types of joint preparation for metal-arc welding with covered electrode,
gas-shielded metal-arc welding, gas welding, TIG welding and beam welding of steel (see Clauses 3 and 4).
It applies to joint preparation for full penetration butt welds and for fillet welds. For partial penetration butt
welds, types of joint preparation and dimensions differing from those specified in this part of ISO 9692 may be
stipulated.
The root gaps referred to in this part of ISO 9692 are those gaps presented after tack welding, if used.
Consideration should be given to altering the joint preparation details (where appropriate) to facilitate
temporary backing, “one-sided welding”, etc.

with the following processes as specified in Tables 1 to 4; combinations of different processes are possible.
a) (3) gas welding; oxyfuel gas welding;
b) (111) manual metal arc welding (metal arc welding with covered electrode); shielded metal arc welding;
c) (13) gas-shielded metal arc welding; gas metal arc welding includes:
 (131) metal inert gas welding; MIG welding; gas metal arc welding;
 (135) metal active gas welding; MAG welding; gas metal arc welding;
 (136) tubular cored metal arc welding with active gas shield; flux cored arc welding;
 (137) tubular cored metal arc welding with inert gas shield; flux cored arc welding;
d) (141) tungsten inert gas welding; TIG welding; gas tungsten arc welding;
e) (5) beam welding:
 (51) electron beam welding;
 (512) electron beam welding in atmosphere;
 (52) laser welding; laser beam welding.
NOTE The numbers in parentheses refer to the reference number of the welding process specified in ISO 4063.
5 Finish
The longitudinal edges of the root face should be de-burred and may be chamfered (up to 2 mm).
6 Type of joint preparation
The recommended types of joint preparation and dimensions are specified in Tables 1 to 4.
