Description

Die am Markt verbreiteten (bekannten) Getränkebehälter, insbesondere für Bier sind sogenannte KEG′s. Die ursprüngliche Bauart war eine dreiteilige Ausführung mit Bodenunterteil in Klöpperform, zylindrischem Mantel/Zwi­ schenstück und einem gewölbten Oberteil gebaut wie größere Druckbehälter. Besonders die Getränkeindustrie und hier insbesondere die Bierbrauer störten sich an den vielen Schweißnähten. Besonders glatte und saubere Nähte konnte man nur erreichen bei einer aufwendigen Spanntechnik und mit einer einwandfreien Badunterstützung; bei der letzten Umfangsschweißung ein technisch schwieriges Unterfangen.
Durch Verbesserungen bei der Tiefziehtechnik gelang es, 2-teilige KEG′s aus Ziehteilen herzustellen. Die Schweißnahtlänge konnte um Faktor 2-2,5 reduziert werden. Aber auch hierbei muß von innen eine Badunterstützung bei dem gebräuchlichen MIG/MAG-Schweißverfahren erfolgen.
Verfahrensbedingt entsteht durch die hohen Temperaturen und lange Einwirkzeiten eine mehr oder minder starke Oxydschichtbildung beim Schweißvorgang.
Um die geforderte Oberflächengüte für den Kontakt mit Bier und sonstigen Getränken in der geforderten Güte zu erreichen, müssen die Fässer gebeizt, elektrolytisch poliert oder zumindest die Oberflächen der Schweißnähte be­ arbeitet werden.
Die Edelstahlbeizung wird mit einem Flußsäuregemisch durchgeführt und ist deswegen unter Umweltgesichtspunkten problematisch und sehr aufwendig.
Über 98% der Faßoberfläche bleibt durch das Zusammenschweißen unbe­ schädigt, so daß für die relativ kleinen Schweißnähte ein unverhältnismäßig großer Beizaufwand betrieben werden muß.
Der Erfindung liegt die Aufgabe zugrunde, Getränkebehälter zu schaffen, die Schweißnähte beinhalten ohne die störenden Anlauffarben bzw. die Oxydschichten. Durch die erfindungsgemäße Schweißung entfällt die teure Nachbehandlung durch Beizen, Elektropolieren, Schleifen oder Bürsten.
Dieses Ziel wird dadurch, daß die Teile, des Getränkebehälters mit einem Zentrieransatz in einer Vorrichtung, über den Zentrieransatz gegeneinander dichtgeschoben und laserverschweißt sind.
Bei der heutigen Produktion wird nach dem Tiefziehen eine Beschneidung des Randes vorgenommen, um diese Teile anschließend mit einer Rundnaht zu einem Behälter zu verschweißen.
Würde man diese Rundnaht laserschweißen, so läßt sich zwar theoretisch auch eine praktisch zunderfreie Schweißnaht erzeugen, aber in der Praxis sind die für das Laserschweißen notwendigen kleinen Spalten von max. 0,1 mm nicht so erreichbar.
Erfindungsgemäß wird eine einwandfreie Laserschweißung bei derartigen Teilen dadurch erreicht, daß die beiden zu verschweißenden Teile in einer Vorrichtung zum Laserrandbeschneiden aufgenommen werden und in dieser Position auch anschließend nach dem dicht Zusammenschieben Laserver­ schweißt werden.
Stellt man bei dem Laserschneiden den Schneidkopf unter einen Winkel bis max. 60° an, so ergibt sich eine sehr vorteilhafte Zentrierfläche.
Nach dem heutigen Stand der Lasertechnik werden hierzu 2 Laserköpfe eingesetzt. Zu dem Laserbeschneiden wird eine spezielle Optik verwendet, und die Laserverschweißung findet unter optimaler Schweißnahtlage mit einem Schutzgas statt.
Vorteilhaft können auch mehrteilige Behälter mit zylindrischem Mittelteil herge­ stellt werden. Es ist ebenfalls denkbar, daß der Schnitt unter Einsatz von Mikroplasma durchgeführt werden kann.
Einzelheiten der Erfindung sind anhand von Ausführungsbeispielen in den Zeichnungen erläutert.
