Principle of Operation

precSYS lets you 3D-position the focalspot onto workpieces with

precise tracking of angles of incidence (AOI). You can simultaneously

vary progression of focal motion, angles of incidence and laser intensities

etc. High-end scan technology with small mirror rotation angles and

low moving masses ensure highly dynamic processing with trepanning

or precession frequencies up to 650 Hz (39 000 rpm). The system

works without any rotary optics.

Advanced digital encoders, control algorithms and application-optimized

servo control enable contour-true, speed independent processing with

maximum precision. The system is servo-regulated for stable positioning

at precession frequencies up to 650 Hz. Specially conceived for USP

precision processing, the opticalpath is polarization-maintaining and

accommodates pulse energies up to 300 µJ at 1030 nm and 65 µJ at

515 nm.

System Design

Active water cooling of beam-guidance components (including galvo axes)

and of spatially separated electronics makes the system robust against

load-dependent temperature fluctuations. Moreover, the system’s innovative

beam guidance provides suitability for up to 50 W lasers.

A sealed, gas-purged optical beam path(overpressure) guarantees optimum

cleanliness even in harsh industrial conditions – thereby enhancing system

service life and processing accuracy.

high power meets high dynamics

The welDYNA scan head enables innovative high power applica

tions by a unique set of properties:

• Suitable for multi-kW lasers

• Designed for highest beam quality (single mode)

• High oscillation frequencies >  2 kHz

• Modular integration with standard collimation and focussing units

• Low long-term and temperature drift

• Fully digital servo circuitry

• Integrated sensor system with real-time monitoring

• Software-independant interlock interface

• Water and air cooling in a robust housing

Typical Applications:

• Welding of dissimilar materials, e. g. aluminum and copper

• Joining of materials with low weldability, e. g. for power

train or body-in-white components

• Cutting of thick metal sheets or fiber-reinforced plastics (FRP)

Typical Industries:

• Automotive

• Mechanical engineering and metalworking

• Aerospace industry

The welDYNA scan head joins high power with high dynamics. The

high power suitability is supported by ultra-low absorption coatings,

air cooling of the mirrors, strict separation of electronics and optical

path and in addition a set of built-in sensors. Empowered by the

fully digital electronics, the integrated sensors provide extensive

possibilities for real-time monitoring of the system’s operational

state. Light-weight SiC mirrors and highly dynamic galvanometer

scanners of the dynAXIS 3 series enable beam oscillation frequen

cies that are unprecedented in high-power scan heads.

An innovative optical configuration leads to opposing beam

entrance and exit apertures, thus facilitating the integration in

gantry- or robot-based machines, e. g. in the automotive or met

alworking industry.

Layout and Principle of Operation

The solidly designed Collimation Module

includes an adapter for mounting the mod

ule and scan system to a machine. Installa

tion is possible from four sides, providing a

high level of integration flexibility.

Various fiber adapters are offered for laser

coupling. The water-cooled, stainless-steel

beam entrance aperture is corrosion-free

even when using DI water. A scale ring

facilitates manual adjustment of the mov

able collimation optic. This allows precisely

setting the focus position to the scan sys

tem’s nominal working distance, as well as

compensating for tolerances.

Housing

The Collimation Module‘s robust housing is

dust and splash proof – particularly at the

junction to the scan head. A replaceable

protective window in front of the collima

tion optic additionally protects the lens

unit from dust infiltration when changing

fibers. This guarantees a long service life in

industrial environments.

Optional Camera Port

The Collimation Module can be optionally

equipped with a camera adapter for process

control or workpiece position detection. The

light arriving from the workpiece is coupled

out of the laser beam path by an integrated

beam splitter and directed to an observation

port. The laser light itself, however, is

nearly fully reflected by the beam splitter to

establish a 90° angle between fiber-in and

beam-out.

fiber connection for scan heads

The Collimation Module enables direct connection of a fiber

coupled laser to a scan head (typical: 30-mm aperture).

Key benefits:

•  Robust housing (water-cooled entrance aperture; stainless steel)

•  Manually adjustable collimation optic, incl. scale ring

•  Optionally with or without camera port (90°/180° variants)

•  Flexible mounting possibilities

•  Replaceable protective window in front of collimation optic

•  Good transmission for red pilot lasers

The module features robust mechanical coupling, along with opti

cal collimation of laser radiation to match the scan head’s aperture.

The employed optical components are suitable for multi-kW laser

powers and adaptable to various beam qualities.

Typical Applications:

•  Welding, micro-welding

•  Cutting

•  Rapid prototyping, additive manufacturing

Typical Industries:

•  Automotive

•  Mechanical engineering and metalworking

smart welding

Designed for robot-assisted welding applications, intelliWELD  

3D scan systems are capable of swiftly positioning the laser 

beam along 3D contours. While a robot guides the scan system 

along a part’s contour, the intelliWELD quickly and accurately 

deflects and fine-positions the laser spot. Complex motions and 

time-wasting robot repositioning are avoided, thereby boosting 

speeds and cutting weld-to-weld positioning time down to a few 

milliseconds. Hence, beam source utilization climbs significantly,  

as does productivity. 

The intelliWELD system’s compactness facilitates straightforward 

mounting onto industrial robots. Its optics are optimized for fiber

coupled disk or fiber lasers with powers up to 8 kW.

The intelliWELD family includes a version with prefocus optics for 

vision-assisted applications (e.g. fillet welding with precise contour 

tracking), as well as the intelliWELD II with integrated zoom axis 

(particularly well-suited for overlap welding, its variable spot size 

enables flexible seam widths).

intelliWELD scan systems use SCANLAB’s fully digital iDRIVE tech

nology, providing an integrated approach to laser and process 

safety. It allows real-time monitoring of all important scan head 

status parameters. And its integrated interlock signal facilitates 

software-independent integration of the scan system into safety 

circuits.

Camera Adapters

The camera adapter allows process observation of the working plane of the galvanometer scanning head by means of a camera. This makes it suitable for process control during laser processing or for inspection of workpiece position and orientation.

Its mechanical interface can be mounted directly between the scanning head and the laser flange. Four camera placement positions are available for setting up the objective unit, ensuring easy integration into existing or new systems.

In order to observe the working plane, the light from there is decoupled in the camera adapter via a beam splitter and imaged onto the sensor via the camera objective. In contrast, laser radiation is transmitted almost unimpeded on its way to the scanning system.

vision for scan heads

The camera adapter enables camera-based observation of a galvanometer scan head’s working field. Typical applications include process monitoring or determination of a workpiece’s orientation during laser processing.

The camera adapter ensures easy integration into new as well as existing systems. The adapter’s mechanical interfaces enable straight forward mounting between the scan head and laser flange. The system allows 4 alternative orientations of the objective with camera.

To facilitate monitoring of work surfaces, light arriving from the workpiece is decoupled via the adapter’s beam splitter and directed through the camera’s objective onto its imaging chip. The laser beam on the other hand passes practically unattenuated through the beam splitter to the scan system. Optical configurations are available for various wavelengths. Customers can freely select a camera suitable for their requirements and attach it via a C-mount.

The camera adapter is specifically designed for maximum observation field size and its integrated iris diaphragm can be adjusted for optimal imaging quality. In addition,color or interference filters can be installed.
