This document defines the rules to be applied for symbolic representation of welded joints on technical
drawings. This can include information about the geometry, manufacture, quality and testing of the
welds. The principles of this document can also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side
and other side on drawings. In this document:
— clauses, tables and figures which carry the suffix letter "A" are applicable only to the symbolic
representation system based on a dual reference line;
— clauses, tables and figures which carry the suffix letter "B" are applicable only to the symbolic
representation system based on a single reference line;
— clauses, tables and figures which do not have the suffix letter "A" or "B" are applicable to both
systems.
The symbols shown in this document can be combined with other symbols used on technical drawings,
for example to show surface finish requirements.
An alternative designation method is presented which can be used to represent welded joints on
drawings by specifying essential design information such as weld dimensions, quality level, etc. The
joint preparation and welding process(es) are then determined by the production unit in order to meet
the specified requirements.
NOTE Examples given in this document, including dimensions, are illustrative only and are intended to
demonstrate the proper application of principles.

1.4   For the purposes of calculations required to be made in accordance with this document, dimensions are in millimetre, pressures are in bar (except otherwise specified), stresses are in newton per square millimetre and temperatures are in degree Celsius.

ISO 15607:2003 defines general rules for the specification and qualification of welding procedures for metallic materials.
It also refers to several other standards as regards detailed rules for specific applications. ISO 15607:2003 is applicable to manual, mechanized and automatic welding.

ISO 2553:2013 defines the rules to be applied for symbolic representation of welded joints on technical drawings. This may include information about the geometry, manufacture, quality and testing of the welds. The principles of this standard may also be applied to soldered and brazed joints.
It is recognized that there are two different approaches in the global market to designate the arrow side and other side on drawings. In ISO 2553:2013: sections, tables and figures which carry the suffix letter "A" are applicable only to the symbolic representation system based on a dual reference line; sections, tables and figures which carry the suffix letter "B" are applicable only to the symbolic representation system based on a single reference line; sections, tables and figures which do not have the suffix letter "A" or "B" are applicable to both systems.
The symbols shown may be combined with other symbols used on technical drawings, for example to show surface finish requirements.
An alternative designation method is presented which may be used to represent welded joints on drawings by specifying essential design information such as weld dimensions, quality level, etc. The joint preparation and welding process(es) are then determined by the production unit in order to meet the specified requirements.

ISO - Taking over of a ISO Technical Corrigendum

ISO 10042:2005 specifies quality levels for imperfections in arc-welded joints in aluminium and its alloys. It applies to material thicknesses above 0,5 mm. It covers full-penetration butt welds and all fillet welds. The principles of the standard may also be applied to partial-penetration butt welds.
Three quality levels are given in order to permit application to a wide range of welded constructions. The quality levels refer to production quality and not to the fitness for purpose of the product manufactured.
The standard applies to:
all types of weld, e.g. butt welds, fillet welds and branch connections;
the following welding processes and their sub-processes as defined in ISO 4063:
131....metal inert gas welding (MIG welding); gas metal arc welding /USA/,
141....tungsten inert gas welding (TIG welding); gas tungsten arc welding /USA/,
15......plasma arc welding;
manual, mechanized and automatic welding;
all welding positions.
Metallurgical aspects, e.g. grain size, hardness, are not covered by the standard.
