部品の加熱方法
Document Type and Number:
Japanese Patent JP2007523285
Kind Code:
A
Abstract:
A processing area of a structural component, such as a gas turbine component, is heated by irradiation with several laser sources prior to and/or during and/or after carrying out a processing such as a deposit welding or machining of the component on the processing area. For the heating, each laser source directs a respective energy beam onto the processing area, which respectively produces an energy spot on the processing area. The respective positions of the energy spots are static or quasi-static on the processing area. The energy spots jointly heat the processing area.
