Welds - Working positions - Definitions of angles of slope and rotation (ISO 6947:1993)
Defines fundamental welding positions and makes possible the location in space of straight welds by means of slope and rotation. Cancels and replaces the recommendations ISO/R 598-1967 and ISO/R 627-1967.
Schweißnähte - Arbeitspositionen - Definitionen der Winkel von Neigung und Drehung (ISO 6947:1993)
Diese Europäische Norm beschreibt die Arbeitspositionen und ermöglicht es, die räumliche Lage der Schweißnähte in Bezug auf eine horizontale Ebene (gewöhnlich parallel zum Werkstattboden) durch den jeweiligen Neigungs- und Drehwinkel festzulegen. Dies ist unabhängig von der umgebenden Konstruktion.
Soudures - Positions de travail - Définitions des angles d'inclinaison et de rotation (ISO 6947:1993)
La présente Norme internationale prescrit les positions de travail et permet la localisation des soudures dans l'espace par rapport à un plan horizontal de référence (généralement parallèle au sol de l'atelier) au moyen d'angles d'inclinaison et de rotation qui ne sont pas liés à la construction environnante.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch 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, govern-
mental 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.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 6947 was prepared by Technical Committee ISO/TC 44,
Welding and allied processes.
This second edition cancels and replaces the first edition (ISO 6947 : 19801, of which it
constitutes a technical revision; reasons for the revision are given in the “lntroduction”

lntroduction
The main reasons for the revision of ISO 6947 : 1980 are given below.
The working positions should be valid for welds in plates and pipes.
The direction of welding is an essential Parameter for determining the working posi-
tion, e.g. up or down; however, in ISO 6947 : 1980, the working direction was not dealt
with.
The working Position is not dependent on the geometrical arrangement of the joint,
e.g. butt or fillet joint, or that of the semi-finished product
The limitations for slope (within O” to 90°) and for rotation (up to a maximum of 1800),
as specified in ISO 6947 : 1980 (clockwise or counter-clockwise), prevent the complete
specification of the weld and the direction of welding in space; it could not, therefore,
be applicable for automatic and robotic welding. lt is intended in this second edition of
ISO 6947 that the whole sphere be included so that welds in all types and all directions
a re covered .
To avoid any misunderstanding, the main positions have been given Symbols which
tan easily be used for designation purposes; these Symbols were Chosen independent-
ly of possible meaningful abbreviations, i.e. they are not derived from any particular
language.
The centreline is normally identical with the Position of the stick electrode. The main
positions have been defined without any tolerantes for slope and rotation. For some
stick electrodes, it may be useful to add the required tolerantes as necessary for their
application. In such cases, the main Position, e.g. flat Position, tan be supplemented
by specifying limits of slope and rotation.

Esch particular Cross-section has its own specific Co-Ordinate

For the purposes of this International Standard, the following
definitions apply.
NOTE - For pipes with inclined axes, the slope is intrinsically
expressed by the welding direction (see 3.2).

of the weld in space and by the working direction.
