The invention relates to a method for producing thin silicon rods (1), comprising the steps: a) providing a rod of polycrystalline silicon, from which at least two thin rods (11, 12) with a reduced cross section in comparison with the polycrystalline silicon rod are separated; b) cleaning the at least two separated thin rods (11, 12) by treatment with a material-eroding liquid medium; c) welding at least two of the cleaned thin rods (11, 12) to form a longer thin rod (1); d) packaging the longer thin rod (1) in a tubular film (100). |
