Civan's dynamic beam laser welds 70 mm thick in a single pass . The Fabricator: "Civan's Dynamic Beam Laser has led to some eyebrow-raising accomplishments, the most recent one announced on Feb. 9, when the company said it completed a single-pass weld that’s 70 mm deep, accomplished at atmospheric pressure—no vacuum required.

Dynamic Beam Laser: Civan Lasers Brings new Technology for Welding Thick Steels to the Market with a Single Pass Weld Civan Lasers has now introduced a new laser technology . This new technology offers a more efficient and cost-effective approach to welding, especially for industries that require welding of 25-70 mm thick steels. Welding has always been a crucial aspect of many industries, including shipbuilding, wind towers, nuclear reactors, boilers, steam plants, and oil and gas pipes. The traditional welding methods, such as GMAW, SAW, and GMA Laser Hybrid, are often time-consuming and resulting a large heat input, leading to large Heat Affected Zones (HAZ) and the use of consumables such as wire filler and flux. Single Pass welds from 25mm up 70mm The traditional laser welding technology could only achieve a maximum penetration of just over 15mm without processing in a vacuum environment. However, with optical phased array (OPA) technology commercialized in the Dynamic Beam Laser , these limitations are no longer an obstacle. Dynamic Beam Laser technology enables efficient laser welding of 25-70 mm thicknesses at atmospheric pressure , eliminating the need for vacuum furnaces and reducing the time and costs associated with multi-pass methods. Illustration of a welding machine specifically designed for panel welding using Dynamic Beam Laser technology The economics of the system are clear. Welding at a feed rate of 10-40mm/sec with only one pass can reduce the total welding time, leading to a welding cost reduction of x30. Furthermore, one laser machine can weld with a capacity of x10 other systems, making it attractive for companies that require deep penetration welding. Civan's Dynamic Beam Laser technology is an optical phased array technology and a type of coherent beam combining (CBC), which merges many single-mode laser beams into one larger beam. This technology provides the flexibility to easily manipulate the beam shape in real-time, without any moving parts, creating a dynamic beam laser. This table compares the Dynamic Beam Laser welding method to traditional welding methods, including Gas Metal Arc Welding (GMAW), Submerged Arc Welding (SAW), and Gas Metal Arc Laser Hybrid (GMA Laser Hybrid). Several shipbuilding companies are already exploring the benefits of Dynamic Beam Laser technology, which has the potential to transform the welding industry and make the welding of thick steels more efficient and cost-effective. Civan Lasers is confident that this technology will provide its customers with a competitive advantage and make welding easier, faster, and more efficient. About Civan Founded in 2008, Civan Lasers stands apart as the sole provider of dynamic beam lasers. With this technology, manufacturers are empowered to manipulate beam shape, frequency, and sequence for optimal results. Dynamic beam lasers eliminate spatter, increase welding power, and allow for faster welding speeds, all while providing the ability to steer and focus the beam. These advanced capabilities unlock a world of new possibilities for a variety of applications. For more information, contact Civan Lasers >

An introduction to Civan's revolutionary laser technology. Download the white paper to learn more about the upcoming changes in the nature of materials processing in the Automotive and Aerospace Industries. Laser technology replaced traditional processes and brought new levels of quality, reliability, and efficiency. However, the industry has continued to evolve with new materials and faster processes - Which is why it is highly important to innovate and improve laser technologies. At the moment, it seems as if materials processing needs to change faster than new laser capabilities are being developed. For example, auto parts are now made from an assortment of alloys and often require the welding of asymmetric parts or dissimilar metals. This creates challenges, and it is particularly difficult to overcome issues of cracking and porosity when welding at high speeds. One of the ways to improve results is by tailoring the beam shape for the process. Download the White paper and learn about Civan's Next-Generation Laser's new capabilities.

The Institut für Strahlwerkzeuge (IFSW) at the University of Stuttgart will study dynamic beam laser welding keyhole fluid dynamics with high-speed X-ray video imaging. Civan Lasers (Jerusalem) has delivered the Institut für Strahlwerkzeuge (IFSW) at the University of Stuttgart an OPA 6 dynamic beam laser (DBL). IFSW researchers will study Civan’s disruptive DBL technology using their unique high-speed X-ray video facility for laser materials-processing diagnostics. The system will allow researchers to view inside the melt pool during laser welding processes, further investigating the opportunities of using DBL technology to improve keyhole stability in industrial welding applications. Other in situ diagnostics such as high-speed cameras and optical sensors reveal only phenomena on the surface of the process. In contrast, the IFSW high-speed, X-ray diagnostics system allows researchers to view with high spatial and temporal resolution the fluid dynamics occurring within process samples. With detection of features well below 250 μm in steel and maximum detection rates exceeding 10,000 Hz, the X-ray imaging system lets researchers better understand the origin of defects such as pores, spatter, and cracking. “Civan’s patented coherent beam combination modulates beam shape as desired at speeds of up to hundreds of megahertz without any moving parts.” “When developing improved laser-based manufacturing techniques for processes such as ablation, drilling, joining, cutting, and additive manufacturing, comprehensive diagnostics of melt pool and keyhole dynamics are crucial for understanding the interaction between laser beams and matter,” says Prof. Rudolf Weber , head of the process development department at IFSW. “We are thrilled to have access to this game-changing laser tool and are eager to improve the understanding of how Civan’s dynamic beam-shaping lasers can influence control of keyhole and melt-pool dynamics and be applied to industry’s most challenging materials-processing applications such as welding thick materials, asymmetric parts, dissimilar metals, and metals with coatings.” Civan’s patented coherent beam combination modulates beam shape as desired at speeds of up to hundreds of megahertz without any moving parts. In addition to beam shape, Civan’s DBLs also enable control of shape frequency, shape sequence, and depth of focus. The ability to control these parameters is a powerful tool for optimization of evaporation in the capillary, the flow in the molten pool, the temperature gradients near the process and with it the solidification of the melt for any laser materials-processing application. Such control does away with pore, spatter, and crack formation while increasing feed rates and speeds in welding and additive manufacturing applications. "IFSW already has projects funded by the Israel Innovation Authority in collaboration with Bosch and with the Israeli Institute of Metals as part of the LAMP [Laser for Advanced Material Processing] consortium," says Civan CEO Dr. Eyal Shekel. “The integration of our OPA 6 laser into IFSW’s X-ray facility will help researchers and industrial companies better understand the impact of laser beam shape, shape frequency, and shape sequencing on weld geometry and microstructure to tap into greater flexibility of laser processing.” About Civan Lasers Civan Advanced Technologies Ltd. was established in 2008 and is the only company to offer dynamic beam lasers. Civan’s dynamic beam lasers allow manufacturers to control beam shape, frequency, sequence, and focus steering to eliminate spatter and increase welding power and speed. Through their advanced capabilities, dynamic beam lasers open the door to countless new applications.
