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.

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 documents 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).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso

.org/iso/foreword .html.

This document was prepared by Technical Committee ISO/TC 44, Welding and allied processes,

Subcommittee SC 7, Representation and terms.

This fourth edition cancels and replaces the third edition (ISO 6947:2011), which has been technically

revised. The main changes compared to the previous edition are as follows:
— Figure 1 and Figure 2 have been revised;

— the concept of a special test position which is not covered by defined test positions has been

introduced;
— editorial corrections/improvements have been made.

Any feedback or questions on this document should be directed to the user’s national standards

body. A complete listing of these bodies can be found at www .iso .org/members .html. Official

interpretations of TC 44 documents, where they exist, are available from this page: https: //committee

Introduction

This document specifies positions for standard discrete test piece orientation, e.g. PA, PB, H-L045, that

have been included in this document since the third edition (ISO 6947:2011).

Since the third edition was published, positions for production welding are also defined. These

positions are flat, horizontal, vertical, and overhead. Unlike discrete testing positions, these positions

are contiguous.

Welding position are not dependent on the geometrical arrangement of the joint, e.g. butt or fillet joint,

or that of the semi-finished product. Welds of all types and in all directions are covered.

The direction of welding (i.e. upwards or downwards) can also contribute to defining welding positions.

The main positions have been given symbols which can easily be used for designation purposes; these

symbols were not derived from any particular language.

The concept of a special test position, not covered by the existing and well-defined positions, has been

included so that testing can be carried out in positions that do not meet the standard requirements.

The relationship between testing positions and production welding positions is specified elsewhere,

e.g. in the ISO 9606 series or ISO 15614 series.
