Hybridschweißen für anspruchsvolle Schweißnähte

(PresseBox) (Hannover, )
Hochfeste Stähle, bekannt aus dem automobilen Leichtbau, finden immer häufiger Einsatz in der Konstruktion, im Schiffbau, in Fahrzeugen und Maschinen der Bauindustrie sowie im landwirtschaftlichen Bereich. Außer einem geringeren Gewicht haben hochfeste Stähle - verglichen mit normalen Baustahl - eine höhere Verschleißfestigkeit und Härte über einen breiten Temperaturbereich.

Allerdings sind hochfeste Stähle relativ problematisch zu schweißen. Bei den meisten Schweißprozessen gehen die positiven Eigenschaften des Grundmaterials (die im sehr komplexen thermo-mechanischen Herstellungsprozess eingestellt werden) in der Schweißnaht und der Wärmeeinflusszone verloren. Außerdem haben diese Stähle einen hohen Kohlenstoffgehalt, der zu Rissen in der Schweißnaht führen kann.
