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

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

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.
INTERNATIONAL STANDARD ISO 6947:2019(E)
Welding and allied processes — Welding positions
1 Scope
This document defines welding positions for testing and production, for butt and fillet welds, in all
product forms.
Annex A gives examples of the limits of the slope of a weld axis and the rotation of the weld face about
the weld axis for welding positions in production welds.
Annex B gives a comparison of this document and US designation systems for welding positions.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
