Laser Scribing of Grain Oriented Electrical Steel Under the Aspect of Industrial Utilization using High Power Laser Beam Sources

摘要: Abstract The core loss of grain oriented electrical steel can be improved by an additional treatment process. For the industrial utilization, CO2 or Nd:YAG lasers are most widely used for laser scribing with typical improvements about 10%. In this work, a high power and fiber up to 4 kW investigated under aspect utilization. It was found that specific parameter range both beam sources necessary improve losses applied range. Furthermore, increase improvement 0.3 mm HiB (High-Permeability) using compared laser.
