Abstract
The filler wire is a closed tube, in whose interior is located a filling of two or more pulverulent material components. With the split tube still open, the filling is introduced in the form of layers and then the split tube is closed. As a result of the filling introduced in layer form, a favorable set of conditions for closing or sealing the tube, for example by welding, is provided.
