Abstract:
1. A method of processing a structural component, comprising: a) providing a structural component that has a processing area which is to be processed; b) producing plural energy beams respectively individually from plural laser sources; c) heating the processing area of the structural component by directing the plural energy beams respectively from the plural laser sources onto the processing area while the laser sources remain stationary relative to the processing area of the structural component, whereby the plural energy beams respectively individually form plural energy spots at respective locations on the processing area and the energy spots heat the processing area of the structural component, and wherein during the heating each respective one of the energy spots respectively remains stationary relative to the processing area; d) respectively individually measuring the heating that is respectively caused by each respective one of the energy spots at the respective locations on the processing area by respectively individually measuring respective actual measured temperature values at the respective locations on the processing area using plural temperature measuring devices that are respectively individually allocated to the plural laser sources; e) respectively individually controlling the plural laser sources in response to the respective actual measured temperature values; and f) performing a mechanical processing, distinct from and in addition to the heating, on the processing area of the structural component, at a time that is at least one of before or during or after the heating.
