Paper Abstract

A fully automated laser process has been installed on a main stream production line for the manufacturing of electrical steel. The process uses high power continuous wave Nd:YAG lasers to refine the magnetic domain structure in a high magnetic permeability sheet steel product. The result is a typical 10% reduction in the electrical energy lost when the steel is used in a transformer core. A mathematical model of the process with dynamic sensor input is used by a computer to control the laser power and scan rate to ensure magnetic quality improvement independent of processing speed.
