Abstract

A small gap abutting arrangement of two weldable plate or hollow body edges prior to butt welding without weld additive, especially a laser weld seam, has abutting edges formed by plate edges having a matching slope which is preferably chosen according to the requisite unevenness correction of the abutting edges. The plates may have different thicknesses and may consist of different materials.

Description

Spaltarmes Aneinanderstoßen von zwei schweißbaren Plattenkanten (1) oder Hohlkörpermantelkanten als Vorbereitung für eine Nahtstumpfschweißung (Fig. 3) ohne Schweißzusatz besonders einer Laserschweißnaht.Low-gap butting of two weldable plate edges ( 1 ) or hollow body edges in preparation for butt welding ( Fig. 3) without welding filler, especially a laser weld.

Für alle Stumpfschweißungen (13) ohne Schweißzusatz (Fig. 3) ist das spaltarme Aneinanderfügen der durch die Schweißung zu verbindenden Teile (3) (4) eine unerläßliche Voraussetzung.For all butt welds ( 13 ) without welding filler ( Fig. 3), the low-gap joining together of the parts ( 3 ) ( 4 ) to be connected by the weld is an essential requirement.

Besteht zwischen den Kanten der zu verbindenden Teile (1) ein Spalt (2), so schießt die Flamme beim Schweißen mit Gasen, oder der Laserstrahl, beim Laserschweißen durch den Spalt (2) und sie nehmen Teile, der für die Schweißung flüssig werdenden Kanten mit. Selbst beim Widerstandsschweißen können flüssig gewordene Kantenteile (9) durch den Spalt tropfen.If there is a gap ( 2 ) between the edges of the parts to be connected ( 1 ), the flame shoots through the gap ( 2 ) when welding with gases, or the laser beam during laser welding, and they take parts of the edges that become fluid for welding With. Even during resistance welding, liquid edge parts ( 9 ) can drip through the gap.

Selbst wenn bei dickeren Platten (3) (4) während des Schweißens der Spalt sich schließt, fällt die Naht von der Schweißquelle aus, (meist oben), mindestens um die durch den Spalt (2) fehlende Masse ein. Dies führt zu einer Querschnittsverringerung und zur Min­ derung der Stabilität.Even if the gap in thicker plates ( 3 ) ( 4 ) closes during welding, the seam falls out from the welding source, (usually at the top), at least by the amount missing from the gap ( 2 ). This leads to a reduction in cross-section and a reduction in stability.

Aufgabe der Erfindung ist es, die gebräuchlichen rechtwinkligen Stoßkanten gegen zur Basisfläche hin gleiche schräge (13) zu tauschen.The object of the invention is to exchange the customary right-angled abutting edges for the same oblique ( 13 ) towards the base surface.

Auch die schrägen Kanten (1) können ungerade sein (5). Durch vertikales Verschieben (6) einer Kante auf die andere feststehende hin, schließt sich der Spalt (2) parziell immer da, und soweit er vorhanden ist.The sloping edges ( 1 ) can also be odd ( 5 ). By vertically shifting ( 6 ) one edge towards the other fixed one, the gap ( 2 ) always closes partially and as far as it is present.

Das Andruckelement (6) (Fig. 1) sollte flexibel sein, gefedert, oder mit einem feuerfesten Schlauch je nach Plattendicke.The pressure element ( 6 ) ( Fig. 1) should be flexible, spring-loaded, or with a fire-resistant hose depending on the plate thickness.

Nach dem Nahtschweißen sind die Plattenflächen (3) (4) an den Kanten (10) zueinander mehr oder weniger uneben. Ist dieser Kantenversatz unerwünscht, so kann die Naht (9) auf einer geschliffenen Schiene (11) liegend (Fig. 4) mit einer darüber geschobenen Rolle (12) geglättet werden, indem sie die Schweiß­ naht (9) auf die Schiene (11) drückt. Mit diesem Verfahren werden die Stumpfschweißnähte (13) voll ausgefüllt. Sie haben die Stabilität der durch die Schweißnaht verbundenen Platten (3) (4) und durch das Glätten sind die Schweißnähte (13) so eben wie die Platten.After the seam welding, the plate surfaces ( 3 ) ( 4 ) are more or less uneven at the edges ( 10 ). If this edge offset is undesirable, the seam ( 9 ) lying on a ground rail ( 11 ) ( FIG. 4) can be smoothed with a roller ( 12 ) pushed over it by welding ( 9 ) onto the rail ( 11 ) presses. With this method, the butt welds ( 13 ) are completely filled. They have the stability of the plates ( 3 ) ( 4 ) connected by the weld seam and, due to the smoothing, the weld seams ( 13 ) are as flat as the plates.

Auch das Stumpfschweißen (Fig. 2) von zwei unterschiedlichen Materialdicken (7) (8) ist mit diesem Verfahren möglich, besonders wenn die Glättrolle (12) den Plattendickenversatz als Profil trägt.Butt welding ( Fig. 2) of two different material thicknesses ( 7 ) ( 8 ) is also possible with this method, especially if the smoothing roller ( 12 ) carries the plate thickness offset as a profile.

Aus Gründen der Wirtschaftlichkeit können die Schweißvorrichtung mit dem flexiblen Kantenandruck und die Glätteinrichtung in einer Vorrichtung kombiniert sein.For reasons of economy, the welding device with the flexible edge pressure and the smoothing device in one Device can be combined.
