Laser Forming of Thick Steel Plates by a 2kW Diode laser with a Kaleidoscope(Physics, Processes, Instruments & Measurements)

概要

論文の詳細を見る
A high power 2kW diode laser system was used for laser forming of 5mm and 10mm thick steel plates. Measurements obtained with thermocouples and a thermo-viewer revealed the temperature and temperature distribution during thick plate laser forming. Finite element analysis was also performed to simulate single pass laser forming. The results were then used to determine the laser parameters for optimum irradiation. Employing these parameters, a 5mm thick plate was bent 13.5 degrees with 30 laser scans at an output power of 1kW and a 10mm thick plate bending of 90 degrees was successfully achieved.
