Abstract

Die Erfindung betrifft ein Verfahren zum Verbinden zweier Werkstücke durch Schmelzschweißen. Aufgabe der Erfindung ist es, ein Verfahren zu entwickeln, bei dem eine hohe Positioniergenauigkeit einer Wärmequelle entlang einer Schweißnaht und ein großes Toleranzfeld für die Abmessungen von Entgasungskanälen möglich ist. Die Erfindung besteht darin, dass bei einem Verfahren zum Verbinden zweier Werkstücke durch Schmelzschweißen, bei dem in mindestens eines der Werkstücke mindestens eine Spur mit mindestens einer Vertiefung eingebracht wird, bei dem die Werkstücke an der Vertiefung zueinander gepaart werden und bei dem entlang der Spur Wärme zugeführt wird, bis Teile der Werkstücke geschmolzen werden, wobei ein Schweißkopf mit einer Wärmequelle relativ zu den Werkstücken positioniert wird, zur Positionierung des Schweißkopfes (1) laufend die Lage der Vertiefung (18, 28, 34-37) anhand von Detektorsignalen bestimmt wird, die geometrische Merkmale der Vertiefung (18, 28, 34-37) wiedergeben, und aus den Detektorsignalen Stellsignale für eine Vorrichtung mit Relativbewegung zwischen Wärmequelle (6) und Werkstücken (11, 12) erzeugt werden.The invention relates to a method for joining two workpieces by fusion welding. The object of the invention is to develop a method in which a high positioning accuracy of a heat source along a weld and a large tolerance field for the dimensions of degassing channels is possible. The invention consists in that in a method for joining two workpieces by fusion welding, in which at least one of the workpieces at least one track is introduced with at least one recess in which the workpieces are mated to each other at the recess and the heat along the track is supplied until parts of the workpieces are melted, wherein a welding head is positioned with a heat source relative to the workpieces, for positioning of the welding head (1) continuously the position of the recess (18, 28, 34-37) is determined by means of detector signals, reproduce the geometric features of the recess (18, 28, 34-37), and from the detector signals actuating signals for a device with relative movement between the heat source (6) and workpieces (11, 12) are generated.
