Laser Welding

Arnold

ARNOLD Ravensburg was founded in Ravensburg in 1919 and has now been in existence for over 100 years. With the current owner, Mr. Thomas Arnold, the company is still family-owned and in 2019 employed around 80 people in our anniversary year.

In 1985 we built our first one Laser welding system manufactured for the gear factory in Friedrichshafen. We have been producing and developing since then complex laser systems including the necessary additional processes, the necessary automation components and the special device technology for laser welding.

Laser Welding Systems

Whether gear wheel, differential, shaft, vibration damper, rotor shaft, die-cast aluminum, copper, electromobility components. All this is possible with our flexible laser welding systems. Various systems are available for different component sizes and cycle time scenarios. In order to achieve the best possible process quality for our customers, we are able to integrate all technologies available on the market such as fiber, disc, diode lasers and CO2 lasers into our systems.

Welding optics, scanners and wobble optics are available as process optics.

Clamping technology and automation are developed by us on a project-specific basis and supplied with the turnkey systems.

3D Laser Center Flex Cell

Our flex cells are as flexible as a Swiss army knife. With 3–7 axes and travel distances from 750x250x250mm to 1200x1200x750mm in the linear axes as well as rotary swivel axes for optics and components, there are almost no limits to the applications.

Processes such as welding, cutting, soldering, polishing, hardening, LMD are exemplary applications on the laser cell.

The use of several different lasers, some of which are integrated at the same time, make the flex cell not only a flexible production system but also the ideal solution for your application laboratory.

LDRS System

Our LDRS systems are a joint development with the Fraunhofer IWS. The Laser Domain Refinement Systems are used to treat grain-oriented electrical steel sheets. The electrical sheet, which is later used in the production of transformers, moves through the system at a high speed of around 100m/min while the focused laser beam is moved over the sheet at 25m/s. The resulting change in the microstructure enables better magnetic reversal properties of the electrical sheets and thus a higher efficiency of the transformer.
