Laser welding research aims for EV manufacturing solutions
September 12, 2022
The laser technology continues to get more sophisticated. A company said to be on the leading edge of this development is Israel-based Civan Lasers. The company received the 2022 Prism Award in the industrial lasers category from SPIE, the international society for optics and photonics, and Photonics Media. The award recognizes Civan’s OPA 6 Weld, a 7- to 14-kW, single-mode, continuous-wave, dynamic beam laser (DBL) technology that modulates beam shape as desired at speeds up to hundreds of megahertz without any moving parts.
Dynamic beam lasers based on coherent beam combining
June 20, 2022
Civan’s Dynamic Beam laser provides a High Power (up to 100 kW), Single Mode, Continuous Wave output with the ability to create arbitrary beam shapes and do beam steering at a speed of 10s of MHz. The Dynamic Beam is derived from using the Coherent Beam Combining (CBC) technology and the Optical Phased Array (OPA) technology. This combination allows to dynamically tailor beam parameters to the required application. The benefits of the Dynamic Beam are significant in many applications such as welding, cutting, drilling, and additive manufacturing. This is due to its ability to have better control of the melt pool and the keyhole, which both affect the quality of products. In cases where the melt pool is not stable, spatter and pores occur and damage the pieces.
Dynamic Beam Laser System Offers Real-Time Look into Melt PoolMaterial Processing
April 27, 2022
Laser developer and manufacturer Civan Lasers has delivered an OPA 6 dynamic beam laser (DBL) to the University of Stuttgart’s Institut fur Strahlwerzeyge (IFSW). The DBL will form a system with IFSW’s high-speed x-ray video facility for laser materials-processing diagnostics. The system will enable researchers to view inside the melt pool during the laser welding process.
Dynamic Beam Lasers: Redefining Flexibility in Material Processing
March 15, 2022
Learn how dynamic beam shaping laser technology overcomes the most challenging high-power laser welding applications. Understand the impact of laser beam shape, shape frequency, and shape sequencing on weld geometry and microstructure. How focus steering helps maintain deep weld seam consistency in thick materials. How to quickly test multiple shapes to optimize laser parameters for specific welds.
Multiphysical Process Simulations Analyze Dynamic Beam Laser Welding
March 3, 2022
Laser experts at the Technical University Wien have collaborated with Civan Lasers to simulate its disruptive dynamic beam laser technology. As the first and only multiphysics simulation software capable of modeling the megahertz-level frequencies of Civan’s dynamic beam lasers (DBLs), the work improves understanding of how these beam-shaping lasers influence control of keyhole and melt-pool dynamics.
Civan partners with Smart Move on welding and additive
January 24, 2022
The two partners say that the combination of Civan’s dynamic beam laser (DBL) with Smart Move’s state-of-the-art laser scan head means that customers are now able to change beam-shape orientation on the fly - meaning that more complex geometries can be formed.
Dynamic Beam Lasers: Possible breakthrough for fuel cell cars
November 15, 2021
The three companies driving the Eureka Project — Civan Lasers in Israel, the Fraunhofer Institute for Laser Technology in Germany, and Smart Move in Germany — are international leaders in the field of laser welding. They aim to solve the welding problem by implementing Civan Lasers’ dynamic beam laser technology, which can wobble the beam in MHz frequencies, creating a faster, more accurate weld of the bipolar plates.
Civan / EU-Funded PULSATE Project Names Winners of 1st Technology Transfer Experiments
October 1, 2021
Proposal partners: BBW Lasertechnik GmbH (Germany) and Civan Advanced Technologies Ltd. (Israel).
Aims: To develop machine build-up of new coherent beam combining technology and experiments of aluminum welding with new beam shaping possibilities.
Fraunhofer IWS and Civan: Flexible 13kW fiber laser developed for rapid materials processing
July 27, 2021
The system is based on the Coherent Beam Combining (CBC) method, which is still new for high-power lasers. The 13 kilowatt laser can generate different energy distribution patterns particularly quickly during operation and thus process even demanding materials precisely and quickly.
The IWS researchers intend to make the innovative laser technology from Israel available to companies worldwide in the near future.
