Hall 11 Hall 11 Our official EuroBLECH 2010 Show Preview gives you an idea of the wide variety of products and services on display in Welcome Hanover this year. On the following pages, hundreds of exhibiting companies provide detailed information about their exhibits, their new technologies and sophisticated solutions. This Show Preview also includes a complete exhibitor list as well as useful travel and on-site information. With this year’s theme 'Time for Innovation', EuroBLECH 2010 will showcase ideas and expertise for the future of sheet metal working. The leading exhibition for this industry sector is the first choice when it comes to sourcing the right machinery, systems, tools and materials. We hope you enjoy reading this Show Preview and look forward to welcoming you to EuroBLECH 2010. Photons are up front Laser beam sources are being used for more and more applications In the last few years, the laser has been used for very fine weld seams, and at the same time able to open a wide range of applications they have extremely small heat affected zones, that where its special characteristics can be used are almost non-existent. This means workpieces with a to advantage. The key characteristics of thickness of only 50µm can be welded, but only if the modern beam sources are apart from better welding edges have been optimized, and there is no energy exploitation, higher beam quality weld gap. Again, the laser is predestined to be used and output powers. for edge preparation, and the right process parameters and equipment can be used for cutting the edges to In the last few years, the laser has established itself have a zero-weld gap, before welding takes place. The firmly in industrial manufacturing, beginning with the main advantage is that one laser can be used for both automobile industry. High feed rates mean the laser cutting and welding, and thus, investment costs are can work cost-effectively for producing semi-finished kept low, while productivity is kept high by intelligent and end products, despite high investment costs. alternation of production steps with product Shorter switch-on times have also helped to reduce transportation. operational costs by reducing power consumption. And for metal sheets of only a few millimetres thickness, rack, up to 30kW systems. Similar units are also High beam qualities can be used to generate feed rates of 9m/min are achievable. The current available for pulsed laser systems. Whereas CO2 lasers workpieces from scratch. Laser-based rapid prototyping transition from rod lasers to fiber, disc and diode lasers are being used more for cutting applications, the trend can build up structures that are thinner than 100µm, is also pushing efficiency to above 30%. Available for welding applications is to use fibre-guided, solid- and which can be used for applications in medicinal beam quality is being used to allow lasers to state lasers. Flexible beam guidance offers great products, or for cutting or stamping tools. Alloy concentrate its energy output on such a small area, so advantages when programming welding seams, and elements or hard particles can also be embedded in a that extremely small and temperature-sensitive even programming for three-dimensional welding has cladding layer during repair welding, to improve wear workpieces can be produced. Medical products and become relatively easy. resistance. components for the automotive and electronic fields, in particular, can profit from smaller and smaller welding However, not only complex or large workpieces can be Even the so-called disadvantages of laser processing, seams or cut kerfs. The range of laser sources with a challenge to welding technologies. Small like weld seam hardening for some materials, can be continual wave output runs from compact systems with components especially tend to be more difficult to used positively. Complex constructions with units with over a kilowatt power that fit into a 19" weld, for example metal foils. Pulsed lasers can be components subject to mechanical stress are presently Exhibitor Profiles 2 Hall 11 Contents strengthened by using higher strength steels or higher Using a laser, it is possible to weld the tubing to the welding technologies. With the help of stationary and material thicknesses. This results in a material mixture back side of the aluminum sheet, without allowing the mobile measurement systems, the LZH is compiling a or more weight. Both alternatives are time and cost temperature on the front side to reach a critical level data base for laser work stations, which will be intensive, from welding and forming the semi-finished which would damage the coating. Simultaneously, available for firms interested in safety. products to their actual use in the finished product. copper and aluminium are mixed in a stable weld spot, However, once the weak points of a component have which can withstand the different thermal expansion Falling prices for purchasing a laser and lower been localized, laser welded seams can be used to values of copper and aluminiun. But copper and operating costs will soon make the use of lasers strengthen them. Since lasers are already an integral aluminum are not the only two-metal-weld that can be attractive for a growing number of applications. This part of most sheet metal working processes, made using the laser. Aluminum and steel, or other will be a future guarantee for the competitive position knowledge concerning the mechanical characteristics steel-based hybrid combinations can also be welded or of a number of firms with high quality products. of laser weld seams and the produced workpieces can soldered. be combined to designate where components strengthening is necessary. Thus, an additional Welding of steel is already state-of-the-art, and it is the production step can be avoided. For example, remote daily business of many small and medium sized Authors: Dipl.-Ing.

Over the last few years, the energy sector has proven a 6kW fiber laser have recently been installed at the to be a growing market. In spite of the general LZH, for use in research projects in these fields. recession, the solar and wind energy fields have had full order books, and have even been able to expand Along with the higher laser output, work safety for their business. This trend is especially true for solar laser applications is becoming more and more thermal energy, where solar energy is used directly to important. Long focal lengths mean that the intensity provide warm water for heating systems. In the heart far from the actual point of work is high enough to of solar thermal systems is the solar absorber, cause damage to people or equipment. In response to consisting of an aluminium sheet and a copper tubing this, both active and passive protection measures with system. Solar energy is transferred from the coated high resistance to laser radiation have been developed, aluminium sheet to a fluid in the copper tubing. Often, which in an emergency situation can actively influence a pulsed laser is used to connect the copper tubing to the production chain. In addition, process emissions the aluminum sheet. The challenge here is the must be removed, typically smoke and particles from thinness of the coated aluminum. Welding calls for a the laser process. This places higher demands on very low heat input, so the coating is not damaged. exhaust systems than for conventional cutting and Exhibitor Profiles 3 Hall 11 Hall 11 welding.
