Resistance welding - Weldability - Part 1: General requirements for the evaluation of weldability for resistance spot, seam and projection welding of metallic materials (ISO 18278-1:2015)

ISO 18278-1:2015 specifies procedures for assessing the generic weldability for resistance welding of uncoated and coated metals.
It is assumed for this and other linked standards that their application is entrusted to appropriately trained, skilled, and experienced personnel.
For the quality of welded structures, the relevant part of ISO 14554 is applicable. The specification of procedures is to follow guidelines as in ISO 15609‑5.
The purpose of the tests are to
a)    compare the metallurgical weldability of different metals,
b)    assess the weldability of differing component designs, e.g. dimensional configuration, stack-up, projection geometry, etc.,
c)    investigate the effect of changes in welding parameters such as welding current, weld time, electrode force or complex welding schedules including pulse welding, current stepping etc. on weldability, and/or
d)    compare the performance of resistance welding equipment.
Precise details of the test procedure to be used will depend on which aspect of items a) to d) will be evaluated relative to the welding result obtained.

Widerstandsschweißen - Schweißeignung - Teil 1: Allgemeine Anforderungen an die Bewertung der Schweißeignung von Widerstandspunkt , Rollennaht- und Buckelschweißungen von metallischen Werkstoffen (ISO 18278-1:2015)

Dieses Dokument legt Verfahren für das Bewerten der allgemeinen Schweißeignung für das Widerstands-schweißen unbeschichteter und beschichteter Metalle fest.
Voraussetzung für die Anwendung dieser Norm und anderer, mit ihr in Zusammenhang stehende Normen ist, dass geeignet ausgebildete, qualifizierte und erfahrene Schweißer eingesetzt werden.
Für die Qualität der geschweißten Konstruktionen sollte der jeweils zutreffende Teil von ISO 14554 angewendet werden. Zur Festlegung der Schweißverfahren sollten die in ISO 15609 5 angegebenen Anleitungen befolgt werden.
Die Prüfungen dienen folgenden Zwecken:
a)   dem Vergleichen der metallurgischen Schweißeignung der unterschiedlichen Metalle und/oder
b)   dem Bewerten der Schweißeignung unterschiedlich gestalteter Bauteile, z. B. der maßlichen Konfiguration, der Schichtung der zu schweißenden Teile, der geometrischen Gestalt des Schweißbuckels usw. und/oder
c)   das Untersuchen des Einflusses von Veränderungen der Schweißparameter auf die Schweißeignung, wie Schweißstrom, Schweißzeit, Elektrodenkraft oder komplizierte Schweißprogramme einschließlich Mehrimpulsschweißen, Stepperfunktion für den Schweißstrom usw. und/oder
d)   dem Vergleichen der Leistungsfähigkeit der Widerstandsschweißeinrichtung.
Die genauen Details des anzuwendenden Prüfverfahrens hängen davon ab, welcher Aspekt der Punkte a) bis d) in Bezug auf das erhaltene Schweißergebnis zu bewerten ist.

Soudage par résistance - Soudabilité - Partie 1: Exigences générales pour l'évaluation de la soudabilité pour le soudage par résistance par points, à la molette et par bossages des matériaux métalliques (ISO 18278-1:2015)

ISO 18278-1:2015 définit les procédures à suivre pour évaluer la soudabilité générique pour le soudage par résistance des métaux revêtus et non revêtus.
Il est attendu que pour la présente norme et les normes associées, leur application soit confiée à un personnel dûment formé, qualifié et ayant de l'expérience.
En ce qui concerne la qualité des structures soudées, la partie correspondante de l'ISO 14554 s'applique. Pour la spécification des modes opératoires, il convient de suivre des lignes directrices telles que l'ISO 15609-5.
L'objectif des essais est de:
a)    comparer la soudabilité métallurgique de différents métaux,
b)    évaluer la soudabilité des différentes configurations d'assemblage, telles que la configuration dimensionnelle, l'empilement de tôles, la géométrie du bossage, etc.,
c)    étudier les effets des changements sur les paramètres de soudage tels que le courant de soudage, le temps de soudage, l'effort de soudage ou les programmes de soudage complexes incluant le soudage avec pulsations, l'incrémentation du courant de soudage, etc.,
d)    comparer les performances des matériels pour le soudage par résistance.
Les détails précis de la procédure d'essai à utiliser dépendent de la nature exacte des points a) à d) à évaluer en rapport avec le résultat obtenu en soudage.
