摘要

Producing a silicon single thin rod comprises providing two thin rods of polycrystalline silicon, and welding of the two thin rods to a longer thin rod by induction welding an induction coil, where in the step of welding of two thin rods for longer thin rod, the temperature is measured at a weld and a thermal output of an induction coil which heats the two thin rods by thermal radiation, is time regulated.
