| 摘要 |
The invention relates to a method of joining at least one aluminium wire to a copper part by soldering or welding. In the method, the ends of two aluminium wires (1) are first disposed in the interior of a copper sheathing (4) then a strip of hard solder (5) is placed on the lamella (2) of a collector (3) onto which the wires (1) are to be soldered, and subsequently an electrode (6), whose lower end is of hat-shaped construction, is placed on the sheathing (4) in order to melt the aluminium and then the hard solder. In the interior of the sheathing, diffusion in the liquid phase takes place between the copper and the aluminium.
