Laser hardening machine for steam turbine blades

Since many years the laser beam hardening of power plant steam engine blades has successfully been proven as wear protection procedure. The company Siemens AG Mühlheim an der Ruhr is going to apply in-house this technology in order to shorten the production process. Fraunhofer IWS provided the unique laser hardening system.

Effective surface hardening with rotational symmetry

IWS scientists designed and completed an innovative laser machine for the industrial hardening of spherical calottes in the automotive industry. The basic concept of this machine is the particular rotating mirror optics, which allows, combined with the measuring system »E-MAqS« and the control system »LompocPro«, a precisely adjusted process management.
