Dieses Dokument legt spezifische Prüfverfahren zur Bestimmung des zulässigen Schweißstrombereiches und der Elektrodenstandmenge für das Punktschweißkleben unter Verwendung des Widerstandspunkt-schweißens in Zusammenhang mit Kleben fest.
Dieses Dokument ist zur Bewertung der Schweißeignung von vorbereiteten Baugruppen anwendbar, die aus unbeschichteten und beschichteten Blechen mit individuellen Dicken von 0,4 mm bis 6,0 mm bestehen.

Soudage par résistance - Soudabilité - Partie 3: Méthodes d'évaluation de l'aptitude au soudocollage par points (ISO 18278-3:2017)

ISO 18278-3:2017 spécifie une méthode d'essai spécifique permettant la détermination du domaine de soudabilité acceptable et de la durée de vie des électrodes pour le soudocollage par point qui est l'association du soudage par résistance par point et du collage.
ISO 18278-3:2017 est applicable à l'évaluation de la soudabilité d'assemblages de tôles de métal revêtues et non, d'épaisseurs individuelles comprises entre 0,4 mm et 6,0 mm.

Uporovno varjenje - Varivost - 3. del: Postopki vrednotenja varivosti pri hibridnem načinu točkovnega uporovnega varjenja in lepljenja (ISO 18278-3:2017)

Ta dokument podaja posebne preskusne postopke za določanje sprejemljivega razpona varilnega toka in življenjske dobe elektrode za točkovno varjenje, ki povezuje uporovno točkovno varjenje z lepljenjem. Ta dokument se uporablja za oceno varivosti pripravljenih sestavov neprevlečenih in prevlečenih kovinskih plošč s posameznimi debelinami od 0,4 do 6,0 mm.
