Abstract
The present invention relates to a method for laser welding conductor wires (), in particular conductor wires () arranged in slots () of a core () of a dynamo electric machine, such as a stator core, to form a winding and a device () for laser welding conductor wires (). A first end () of a first conductor wire () and a second end () of a second conductor wire () are arranged adjacent to each other. A laser beam is applied to a first end surface () of the first conductor wire () and a second end surface () of the second conductor wire () to weld together the first end () of the first conductor wire () and the second end () of the second conductor wire (). The first end surface () and the second end surface () point upwards, preferable the first end surface () and the second end surface () are axial end surfaces. A laser beam () is applied in a first substantially closed path () within the first end surface () to form a first molten pool (). The laser beam () is applied in a second substantially closed path () within the second end surface () to form a second molten pool (). The laser beam () is applied in a third substantially closed path () to the first end surface () and to the second end surface () connecting the first and second molten pool.
