EN ISO 11970:2007

Specification and approval of welding procedures for production welding of steel castings (ISO 11970:2001)

This International Standard specifies how a welding procedure specification (WPS) for production welding of steel castings is approved.
It defines the conditions for the execution of welding procedure approval tests and the limits of validity of an approved welding procedure for all practical welding operations wi thin the range of essential variables.
Tests shall be carried out in accordance with this International Standard unless additional tests are specified by the purchaser or by agreement between the contracting parties.
This International Standard applies to the arc welding of steel castings. The principle of this International Standard may be applied to other fusion welding processes subject to agreement between the contracting parties.
In the case of specific service, material or manufacturing conditions, more comprehensive tests may be specified by the purchaser, than are specified by this International Standard, in order to gain more information, e.g; longitudinal weld tensile tests, bend tests, chemical analyses, ferrite determination in ausferritic stainless steels, elongation, Charpy "V" impact tests, radiography, etc. ;

Anforderungen und Anerkennung von Schweißverfahren für das Produktionsschweißen von Stahlguss (ISO 11970:2001)

Diese Internationale Norm legt fest, wie die Schweißanweisung (welding procedure specification = WPS) für Produktionsschweißungen von Stahlguss anerkannt wird.
Es werden Bedingungen für die Durchführung der Anerkennung von Verfahrensprüfungen und die Grenzen der Gültigkeit eines anerkannten Schweißverfahrens für alle praktischen Schweißtätigkeiten im Bereich der grundlegenden Einflussgrößen definiert.
Prüfungen sind in Übereinstimmung mit dieser Internationalen Norm durchzuführen, wenn nicht zusätzliche Prüfungen durch den Kunden oder durch Übereinkunft zwischen den Vertragsparteien festgelegt werden.
Diese Internationale Norm gilt für das Lichtbogenschweißen von Stahlguss. Die Prinzipien dieser Internationalen Norm dürfen auch auf andere Schmelzschweißverfahren angewendet werden, falls es eine entsprechende Übereinkunft zwischen den Vertragsparteien gibt.
Umfassendere Prüfungen, als sie in dieser Internationalen Norm aufgeführt sind, dürfen zur besseren Information des Kunden von diesem für bestimmte Einsatz , Werkstoff  oder Herstellbedingungen verlangt werden, z. B. Längszugversuche an der Schweißnaht, Biegeversuche, chemische Analysen, Ferrit Bestimmung in austenitischen nicht rostenden Stählen, Dehnung, Charpy V Kerbschlagbiegeversuch, Durchstrahlung usw.
