| Laser Surface Engineering – the CO2-Laser System |
|
The CO2-Laser operates with gas as active laser medium and is still most frequently used in industrial applications. Due to its very good beam quality it is well suited for keyhole welding applications as well as laser metal forming i.e. build-up welding and laser cladding applications. Sulzer Innotec is doing business with its CO2-Laser system since 1988, assuring the state of technology by periodic refits.

Integrated Contour Recognition System
A laser welding system for build-up welding with powder is a complex machine tool. The advantages of CNC-controlled precision welding must be weighed against the setup effort necessary for the accurate programming of the system. In general, setup time is significantly greater than welding time. In the case of large-area free-form surfaces in particular, the integrated contour recognition system in the laser welding system from Sulzer Innotec helps to reduce the setup effort and thereby the setup costs, as well as improving the setup quality. Moreover, the portal robot can be used as a large digitizing system, for example, in reverse-engineering applications.

The digitizing head with a touch-sensitive
tracer pin makes rapid automated
digitization possible, even for complex
geometrical shapes. |
Once the geometry has been scanned,
the tracer pin is replaced by a powder
nozzle, and the build-up welding can
begin. |
