Abstract

Es wird eine Laserstrahlschweißvorrichtung und ein Laserstrahlschweißverfahren zur Erzeugung einer, insbesondere ringförmigen, Schweißnaht an einem Bauteil vorgeschlagen, wobei die Laserschweißvorrichtung eine Laserstrahlquelle sowie mindestens ein erstes Laserstrahlumlenkmittel und ein zweites Laserstrahlumlenkmittel aufweist, wobei die Laserstrahlquelle zur Erzeugung eines ersten Laserstrahls konfiguriert ist, wobei das erste Laserstrahlumlenkmittel zur Umlenkung des ersten Laserstrahls in einen zweiten Laserstrahl konfiguriert ist, wobei das zweite Laserstrahlumlenkmittel zur Umlenkung des zweiten Laserstrahls auf das Bauteil konfiguriert ist und wobei das erste Laserstrahlumlenkmittel beweglich gegenüber dem zweiten Laserstrahlumlenkmittel ausgebildet ist. Weiterhin wird eine Laserstrahlschweißvorrichtung und ein Laserstrahlschweißverfahren zur Erzeugung einer, insbesondere ringförmigen, Schweißnaht auf einem Bauteil, mit mindestens einer Laserstrahlquelle zur Erzeugung eines Laserstrahls mit einer Hauptausbreitungsrichtung vorgeschlagen, wobei das Bauteil im Wesentlichen senkrecht zur Hauptausbreitungsrichtung des Laserstrahls beweglich angeordnet ist.
