The invention relates to a method for joining two workpieces (11, 12) by fusion welding. The aim of the invention is to develop a method wherein it is possible to place a heating source in a highly precise manner along a weld and a large field of tolerance can be obtained for the dimensions of the degassing channels. The inventive method for joining two workpieces (11, 12) by fusion welding consists in the following: a track with at least one recess (18) is created in at least one (11) of the workpieces (11,12); the workpieces (11,12) are paired together at said recess (18) and heat is guided along the track until parts of the workpieces (11,12) melt; a welding head (1) with a heat source is positioned in relation to the workpieces (11,12); in order to position the moving welding head (1), the recess (18) is determined by means of detector signals (15,16) reproducing the geometric characteristics of the recess (18) and actuating signals are produced for a device with relative movement between the heating source (6) and the workpieces (11,12) from the detector signals (15,16). |
