Abstract
Verfahren zum Schweißen zweier zu verbindender verzinkter Bleche (1, 2) mit einander überlappenden Randbereichen (3, 4; 18, 19), insbesondere im Karosseriebau, wobei die Randbereiche (3, 4; 18, 19) sich unter Bildung eines taschenförmigen Spaltes (8; 20) längs einer anzubringenden Schweißnaht (9; 23) wenigstens beinahe berühren und der Spalt (8, 20) in vorgegebenen Abständen unterbrochen ist und daß die Randbereiche (3, 4; 18, 19) im Bereich dieser Unterbrechungen (5, 6; 16, 17) vollflächig aufeinanderliegen, dadurch gekennzeichnet, dass die Bleche durch Punktschweißung (10, 11; 21, 22) der Unterbrechungen (5, 6; 16, 17) geheftet werden bevor die Schweißnaht (9; 23) gelegt wird.Method for welding two galvanized sheets (1, 2) to be joined with overlapping edge regions (3, 4, 18, 19), in particular in the bodywork, the edge regions (3, 4, 18, 19) forming a pocket-shaped gap (3, 4, 18, 19) 8, 20) are at least almost in contact with one another along a weld seam (9, 23) to be attached, and the gap (8, 20) is interrupted at predetermined intervals, and in that the edge regions (3, 4, 18, 19) in the region of these interruptions (5, 6 16, 17) over the entire surface, characterized in that the sheets are tacked by spot welding (10, 11, 21, 22) of the interruptions (5, 6, 16, 17) before the weld (9, 23) is laid.
Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruchs.The The invention relates to a method according to the preamble of the claim.
Im Karosseriebau werden aus Korrosionsschutzgründen bisweilen verzinkte Bleche benutzt. Bei der Verbindung zweier solcher Bleche durch Schweißen sind besondere Gestaltungsregeln zu beachten, damit einerseits eine dauerhafte Schweißverbindung überhaupt zustande kommt und andererseits eine Verletzung der Zinkhaut weitestgehend vermieden wird.in the Bodywork corrosion protection reasons sometimes galvanized sheets used. When connecting two such sheets by welding special design rules to be observed, so on the one hand a permanent Welded joint at all on the other hand, a violation of the zinc skin largely avoided becomes.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Verfahren aufzuzeigen, das die Schweißbarkeit der Bleche verbessert.Of the Invention is based on the object, a generic method demonstrate the weldability the sheets improved.
Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.These Task is with the characterizing features of the claim 1 solved.
Eine vorteilhafte Ausgestaltung der Erfindung ist Gegenstand des Unteranspruchs. Eine solche Ausführung läßt sowohl eine Punktschweißung als auch eine Nahtschweißung zu. Dabei können mit der Punktschweißung die Bleche zunächst geheftet werden; mit der anschließenden Nahtschweißung, beispielsweise mittels einer Laserstrahlschweißeinrichtung, wird dann die erforderliche Festigkeit, gegebenenfalls auch eine Dichtheit im Übergangsbereich zwischen den beiden Blechen erreicht.A advantageous embodiment of the invention is the subject of the subclaim. Such an execution lets both a spot weld as also a seam weld to. It can with spot welding the sheets first be stapled; with the subsequent seam welding, for example by means of a laser beam welding device, then becomes the required strength, optionally also a Tightness in the transition area between reached the two sheets.
Zwei Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnungen erläutert. Darin zeigen:Two embodiments The invention will be explained below with reference to the drawings. In this demonstrate:
