Welding - Arc-welded joints in aluminium and its alloys - Quality levels for imperfections (ISO 10042:2005)

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.

Soudage - Assemblages en aluminium et alliages d'aluminium soudés à l'arc - Niveaux de qualité par rapport aux défauts (ISO 10042:2005)

L'ISO 10042:2005 fournit des niveaux de qualité par rapport aux défauts dans les assemblages en aluminium et alliages d'aluminium soudés à l'arc. Elle s'applique à des épaisseurs de matériau supérieures à 0,5 mm. Elle couvre les soudures bout à bout à pleine pénétration et toutes les soudures d'angle. Les principes de la présente norme peuvent aussi s'appliquer aux soudures bout à bout à pénétration partielle.
Trois niveaux de qualité sont donnés dans le but de permettre son application à une large gamme de fabrications soudées. Les niveaux de qualité se rapportent à la qualité de la fabrication et non à l'aptitude à l'emploi du produit fini.
L'ISO 10042:2005 s'applique:
à tous les types de soudures, par exemple soudures bout à bout, soudures d'angle et piquages;
aux procédés de soudage suivants et à leurs sous-catégories définies dans l'ISO 4063:
131, soudage à l'arc en atmosphère inerte avec fil électrode (MIG);
141, soudage à l'arc en atmosphère inerte avec électrode de tungstène (TIG);
15, soudage à l'arc au plasma;
au soudage manuel, mécanisé et automatique;
à toutes les positions de soudage.
L'ISO 10042:2005 ne traite pas des aspects métallurgiques, par exemple la grosseur de grain ou la dureté.

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 10042 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee

SC 10, Unification of requirements in the field of metal welding.

This second edition cancels and replaces the first edition (ISO 10042:1992), which has been technically

revised.

Introduction

This International Standard should be used as a reference in drafting application codes and/or other

application standards. It contains a simplified selection of arc welding imperfections based on the designations

given in ISO 6520-1.

Some imperfections described in ISO 6520-1 have been used directly and some have been grouped together.

The basic numerical referencing system from ISO 6520-1 has been used.

The purpose of this International Standard is to define the dimensions of typical imperfections which might be

expected in normal fabrication. It may be used within a quality system for the production of welded joints. It

provides three sets of dimensional values from which a selection can be made for a particular application. The

quality level necessary in each case should be defined by the application standard or the responsible designer

in conjunction with the manufacturer, user and/or other parties concerned. The quality level will have to be

prescribed before the start of production, preferably at the enquiry or order stage. For special purposes,

additional details may to be prescribed.

The quality levels given in this International Standard provide basic reference data and are not specifically

related to any particular application. They refer to the types of welded joint in fabrication and not to the

complete product or component itself. It is possible, therefore, that different quality levels are applied to

individual welded joints in the same product or component.

It would normally be expected that for a particular welded joint the dimensional limits for imperfections could

all be covered by specifying one quality level. In some cases, it may be necessary to specify different quality

levels for different imperfections in the same welded joint.

The choice of quality level for any application should take account of design considerations, subsequent

processing (e.g. surfacing), mode of stressing (e.g. static, dynamic), service conditions (e.g. temperature,

environment) and consequences of failure. Economic factors are also important and should include not only

the cost of welding but also of inspection, test and repair.

Although this International Standard includes types of imperfection relevant to the arc welding processes

given in Clause 1, only those which are applicable to the process and application in question need to be

considered.

Imperfections are quoted in terms of their actual dimensions, and their detection and evaluation may require

the use of one or more methods of non-destructive testing. The detection and sizing of imperfections is

dependent on the inspection methods and the extent of testing specified in the application standard or

contract.

This International Standard does not address the methods used for the detection of imperfections. However,

ISO 17635 contains a correlation between the quality level and acceptance level for different NDT methods.

This International Standard is directly applicable to visual examination of welds and does not include details of

recommended methods of detection or sizing by other non-destructive means. It should be considered that

there are difficulties in using these limits to establish appropriate criteria applicable to non-destructive testing

methods such as ultrasonic, radiographic and penetrant testing and they may need to be supplemented by

requirements for inspection, examination and testing.

The values given for imperfections are for welds produced using normal welding practice. Requirements for

smaller (more stringent) values as stated in quality level B may include additional manufacturing processes,

e.g. grinding, TIG dressing.

Requests for official interpretation of any aspect of this International Standard should be directed to the

secretariat of ISO/TC 44/SC 10 via your national standards body. A complete listing of these bodies can be

found at www.iso.org.

INTERNATIONAL STANDARD ISO 10042:2005(E)
Welding — Arc-welded joints in aluminium and its alloys —
Quality levels for imperfections
1 Scope

This International Standard 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 this International Standard may also be applied to partial-penetration butt welds.

Quality levels for beam-welded joints are presented in ISO 13919-2.

Three quality levels are given in order to permit application to a wide range of welded constructions. They are

designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished

weld. The quality levels refer to production quality and not to the fitness for purpose (see 3.2) of the product

manufactured.
This International 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 this International Standard.
