Abstract

For most laser hardening industrial applications, CO₂ laser with power in the range 1-10 kW are used. To obtain the proper hardened path and thickness it is usually necessary to set up an optical system to guarantee the required beam energy distribution on the component. Beam shaping techniques using static and moving optical components will be discussed evaluating their reliability for an industrial environment. Two examples of beam shaping system are described; both employed with a stationary component and a computer controlled path. The first optical system uses a three mirror rotating homogenizer to heat treat cylinder bores of about 100 mm. The second system includes a light pipe integrated at the end of a laser robot cartesian system to heat treat large 3 dimensional components.
