Resistance welding - Spot welding of aluminium and aluminium alloys - Weldability, welding and testing (ISO 18595:2007)
ISO 18595:2007 specifies requirements for resistance spot welding in the fabrication of assemblies of aluminium sheet, extrusions (both work- and age-hardening alloys) and/or cast material comprising two or three thicknesses of metal, where the maximum single (sheet) thickness of components to be welded is within the range 0,6 mm to 6 mm.
ISO 18595:2007 is applicable to the welding of sheets or plates of dissimilar thickness where the thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses where the total thickness is less than or equal to 9 mm.
Welding with the following types of machines is within the scope of ISO 18595:2007: pedestal welding machines; gun welders; automatic welding equipment where the components are fed by robots or automatic feeding equipment; multi-welders; robotic welders.
The welding of coated material, e. g. zinc coated or anodised material, is not within the scope of ISO 18595:2007.
Widerstandsschweißen - Punktschweißen von Aluminium und Aluminiumlegierungen - Schweißeignung, Schweißen und Prüfungen (ISO 18595:2007)
Diese Internationale Norm legt Anforderungen für das Widerstandspunktschweißen bei der Herstellung von Verbindungen aus Aluminiumblech, Strangpressprofilen (kaltverfestigte und ausgehärtete Legierungen) und/oder Gusswerkstoffen im Zwei- oder Dreilagen-Punktschweißen fest. Dabei liegt die maximale Einzelblechdicke der zu schweißenden Bauteile in einem Bereich von 0,6 mm bis 6 mm.
Diese Internationale Norm gilt für das Schweißen von Blechen oder Platten verschiedener Dicke, wobei das Dickenverhältnis kleiner oder gleich 3:1 ist. Sie gilt für das Dreilagenschweißen bis zu einer Gesamtdicke von 9 mm.
Schweißen mit den folgenden Maschinenarten fallen in den Anwendungsbereich dieser Internationalen Norm:
Ständerschweißanlagen;
Punktschweißgeräte mit Stoßelektrode;
Automatik-Schweißeinrichtungen, bei denen die Bauteile von Robotern oder automatischen Vorschubeinrichtungen zugeführt werden;
Vielpunktschweißanlagen;
Schweißroboter.
Angaben über geeignete Schweißeinrichtungen sind in Anhang A enthalten und über Punktschweiß-bedingungen in Anhang B. Letztere dienen nur zur Information und können Änderungen erforderlich machen, abhängig von den Betriebsbedingungen bei der Herstellung, der Art der Schweißeinrichtung, den Kenndaten des Sekundärstromkreises, dem Elektrodenwerkstoff und der Gestaltung.
Schweißen von beschichtetem Werkstoff, z. B. Werkstoffe mit Zinküberzug oder anodisierte Werkstoffe, fallen nicht in den Anwendungsbereich dieser Internationalen Norm.
Soudage par résistance - Soudage par points de l'aluminium et des alliages d'aluminium - Soudabilité, soudage et essais (ISO 18595:2007)

L'ISO 18595:2007 s'applique au soudage de tôles ou de plaques d'épaisseurs différentes et dont le rapport entre les épaisseurs est inférieur ou égal à 3:1. Elle s'applique au soudage de trois épaisseurs dont l'épaisseur totale est inférieure ou égale à 9 mm.
Le soudage avec les types de machines suivantes entre dans le domaine d'application de l'ISO 18595:2007: machines de soudage avec commande au pied; machines à souder à pistolet; matériel de soudage automatique avec lequel les composants sont mis en place par des robots ou par des appareils d'alimentation automatique; machines à souder multipoints; et robots de soudage.
Le soudage de matériaux revêtus (les matériaux galvanisés ou anodisés par exemple) n'entre pas dans le domaine d'application de l'ISO 18595:2007.

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 18595 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 6, Resistance welding.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 6 via your national standards body, a complete listing of which can be found at

INTERNATIONAL STANDARD ISO 18595:2007(E)
Resistance welding — Spot welding of aluminium and
aluminium alloys — Weldability, welding and testing
1 Scope
This International Standard specifies requirements for resistance spot welding in the fabrication of assemblies
of aluminium sheet, extrusions (both work- and age-hardening alloys) and/or cast material comprising two or
three thicknesses of metal, where the maximum single (sheet) thickness of components to be welded is within
the range 0,6 mm to 6 mm.
This International Standard is applicable to the welding of sheets or plates of dissimilar thickness where the
thickness ratio is less than or equal to 3:1. It applies to the welding of three thicknesses where the total
thickness is less than or equal to 9 mm.
Welding with the following types of machines is within the scope of this International Standard:
⎯ pedestal welding machines;
⎯ gun welders;
⎯ automatic welding equipment where the components are fed by robots or automatic feeding equipment;
⎯ multi-welders;
⎯ robotic welders.
Information on appropriate welding equipment is given in Annex A and on spot welding conditions in Annex B.
The latter are for guidance only and may require modification depending on service conditions of the
fabrication, type of welding equipment, characteristics of the secondary circuit, electrode material and
geometry.
The welding of coated material, e.g. zi
