ÖNORM EN ISO 17641-1:2004-10

Действует
Destructive tests on welds in metallic materials - Hot cracking tests for weldments - Arc welding processes - Part 1: General (ISO 17641-1:2004)
This standard gives an introduction to the fundamentals of hot cracking in weld metals and parent alloys, and
briefly describes the tests available for arc welding processes.
Part 2: Self restraint tests - specifies the tests which should be used to assess the susceptibility to hot
cracking of weld metals. The strains to cause cracking are provided by the restraint of the weldment.
Part 3: Externally loaded tests - describes the tests which can be used to assess the susceptibility to hot
cracking of parent alloys and weld metals. The strains to cause cracking are provided by external loading
on the test specimen.
NOTE The tests in part 3 require the use of non-standardised proprietary equipment and different laboratories use
various procedures, test conditions and specimen sizes, therefore reproducibility within a given laboratory is usually good
but differences between laboratories are sometimes found.
Neben einer Beschreibung der Grundlagen der Heißrissbildung werden das Prinzip zur Prüfung der Heißrißempflindlichkeit von Schweißzusätzen, Grundwerkstoffen und Schweißverbindungen festgelegt und die am meisten genutzten Prüfungen charakterisiert. Als Ergänzung werden eine Übersicht über die Heißrissprüfverfahren, ihre Einteilung in EN ISO 17641-2 und EN ISO 17641-3 und ihre Anwendungsbereiche angegeben.
