Product Portfolio
  • New: QIROX Laser Cell

  • Laser welding and cutting with highest precision

    Precise, quick and reliable: The use of laser beams in the welding and cutting technology offers many advantages. CLOOS presents the QIROX Laser Cell, a new product line of compact cells for automated laser cutting and welding.

    The demands on productivity, repeatability and quality are continuously increasing in industrial production. This has to be met by the welding and cutting technology, too. Modern welding technologies allow increasing the quality, productivity and efficiency of the complete production process. The importance of laser welding and cutting in particular will grow in future. The main reasons for this are the high efficiency and accuracy of the laser beam. Laser welding and cutting often allows a much higher process speed with at the same time a better quality than with conventional processes. The exact work with a precise heat input minimises the heat affection and thus the thermal distortion. This reduces any time-consuming rework to a minimum.

    With the QIROX Laser Cell CLOOS developed an extensive range of laser cells for maximum efficiency and quality. Each laser cell system is a tailor-made unit with components which match each other perfectly. They do not require much space and can be easily integrated into any production. The turnkey systems consist of a laser welding head, safety equipment, operating terminal, positioner, QIROX robot, flat screen with HD camera for visualisation and a pre-assembled media room.

    The laser cells are equipped with a high-tech diode laser offering a maximum electrical efficiency. Other features of this laser type are the high availability, low maintenance expenditure, easy operation and an excellent process stability.

    The 2-station systems are available with different types of positioners for different workpieces and can be loaded from outside. At one end employees can remove the welded workpieces, check the quality of the welding and reload the system while the welding process takes place at the other end. This results in an enormous saving on time for the whole process.

                • Material: Thin plate up to 4 mm
                • Location: Agrostroj

                Modern harvesting machines are very complex units which allow to carry out many steps of the harvesting process in a confined space. To ensure highest reliability the individual components must be perfectly constructed regarding functionality, robustness and weight. A welding robot mounted overhead on a C-frame welds different medium-sized thin plate components. The robot system is equipped with a double-station positioner which changes the station with a horizontal rotary axis. Each of the two stations is equipped with a turn/tilt positioner with counter bearing. Due to the arrangement of the turn/tilt axes even complex workpieces can be perfectly positioned for welding. Thus positions which are difficult to access can be reached and an optimum weld quality is achieved. The stations have quick clamping systems so that the working stations can be retrofitted to another workpiece within a few minutes. Thus retrofit times are reduced to a minimum and the efficiency of the robot system is guaranteed also in the case of frequent retrofits.

                In the Saxon AMS Apparate-Maschinen-Systeme Technology GmbH production the time-consuming manual work of cutting the stainless steel material is done by a robot. Instead of the previous two days manual work, the robot only needs less than four hours. The robot is equipped with a tactile sensor for an exact workpiece measurement. Thus manual marking-out works are not required. And only a minimum of rework is necessary. The two-station system ensures highest system efficiency because the operator works parallel to the robot. Due to the RoboPlan software the workpieces can be programmed offline on a PC during cutting. This considerably reduces the set-up and downtimes. In addition, there is a high level of conformity from the drawing to the product. In this way AMS can produce reproducible components which will make the subsequent exchange of containers simply possible.

              • The narrow gap welding technology reduces production times by 80 %

                • Component: Turbine bearing housings
                • Process: Narrow gap welding
                • Material: Thick plate from 8 mm on
                • Location: Siemens AG Power Genereation

                For many years, Siemens has belonged to the group of leading manufacturers in the world with innovative gas turbines for power stations. In order to be able to manage the greatly increasing demand and at the same tim e improve the working environment for employees, Siemens is using narrow gap welding by means of robots for handling huge turbine housings weighing up to 80 tons. Up to 300 mm thick plates can be welded without an extensive weld preparation. Compared to the previous manual welding the production time reduces by more than 80 %. There is an enormous potential saving with regard to the filler material, shielding gas and power consumption. And the relatively low heat input reduces the material distortion during welding. The use of the narrow gap technology considerably increases the efficiency of the robot system and leads to an improved welding result.

            • CLOOS Welding processes

            • Increased efficiency due to modern processes
                • Control Weld - Through thick and thin

                • The Control Weld process covers the whole range of controlled arcs. At low power a short arc forms which is particularly advantageous when welding thin steel. When the power is increased the short arc turns to a spray arc. This process has more energy and there is more heat input in the base material and the wire than with the short arc process. The small short circuit proof drop transfer ensures a low-spatter welding process without extensive rework
                • Speed Weld - Pulsed arc process for rapid welding

                • The main advantage of the Speed Weld process is a very directionally stable and powerful arc. Thus relatively high welding speeds can be achieved with the Speed Weld process. Due to the voltage regulation of the pulse phase the arc stabilises itself because of the internal control. The Speed Weld process is used in all sectors of industrial production and is perfectly suitable for joining components with different plate thicknesses.
                • Vari Weld - for aluminium welding and MIG brazing

                • The Vari Weld process creates an extremely low spatter pulsed arc. Its special strengths are the welding of aluminium and MIG brazing, where due to the low temperature the base material remains metallurgically unaffected and the corrosion protection is maintained. This process offers completely stable arc conditions and an outstanding controllable weld pool even under varying external influences
                • Rapid Weld - That's what efficiency looks like!

                • The Rapid Weld process is a high-capacity spray arc. The special control generates a very focused stable arc with a very high arc pressure. Via special electrical parameter you can adjust either a wide arc or a narrow focused arc thus exactly modelling the penetration profile. Due to the very small opening angle filler material and shielded gas can be reduced. Considerably less welding beads are necessary thus reducing the welding time additionally. The Rapid Weld process provides advantages wherever high penetration depths and a safe root fusion are required. It is particularly suited for automated applications in industries such as construction machinery, shipbuilding and railway vehicle construction.
                • Cold Weld - Welding with minimum heat input

                • With the Cold Weld process an alternating current produces a very special pulse form, which brings about an extremely low heat input. Due to this type of heat-reduced kind of arc welding the welding process can be optimally controlled. The increased deposition rate can either be used for more filling volume or higher welding speed. The material is only subjected to minimum heat and the original material properties remain to a large extent unchanged.
                • Tandem Weld - Efficient welding times two

                • The Tandem process is the further development of the double wire process. Two electrically independent arcs burn in a common molten pool. The high deposition rate results in weld speed or volume filling. Different process combinations are reached by the electrical separation of the wire electrodes. On the one hand you can select the electrical parameters independently from each other, on the other hand different wire diameters and materials can be used. This possibility opens up entirely new combinations and results in enormous deposition rates of up to 25 kg/h. Weld speeds of up to 4.5 m/min. can be realised when welding thin plates
                • Narrow gap welding - Revolution for thick plate welding

                • The MIG/MAG Narrow gap technology offers a particular economic efficiency for welding thick-walled component parts. Thus, the weld seam volume can be reduced by about 60% in comparison to the conventional weld seam preparation. Thus we enable you to significantly reduce welding time and provides a considerable potential saving with regard to the filler material, shielding gas and power consumption. The basis of the narrow gap technology is the rectangular narrow gap blade with a length of up to 400 mm which guides the wire electrode, the shielding gas and the cooling water. The weld seams with the typical constant seam structure meet the highest quality demands. The relatively low energy supply during narrow gap welding provides special advantages even for steel and for high-strength fine grained structural steel
                • TIG Welding process – Clean, precise and reliable

                • With the CLOOS products for TIG welding you are always a pinpoint ahead. Our TIG power sources weld clean, precisely and reliably all over the world. But we also offer small and compact inverter technology for workshop and trade. Thin plates or pipe constructions: CLOOS has the right products for all materials and the most different components. The TIG process is very good for automation purposes and application at the robot. As the welding power is not coupled to the wire feed, the deposition rate can be controlled independently from the electrical power and thus perfectly adapted to the welding task. So the TIG process creates very high-quality, spatter-free weld seams.
                • TIG Welding with cold wire - Clean, precise and reliable

                • With the CLOOS products for TIG welding you are always a pinpoint ahead. Our TIG power sources weld clean, precisely and reliably all over the world. But we also offer small and compact inverter technology for workshop and trade. Thin plates or pipe constructions: CLOOS has the right products for all materials and the most different components. The TIG process is very good for automation purposes and application at the robot. As the welding power is not coupled to the wire feed, the deposition rate can be controlled independently from the electrical power and thus perfectly adapted to the welding task. In the case of an automatic supply a distinction is made between hot wire feeding and cold wire feeding. When feeding cold wire, the filler material is led to the welding spot without current and molten in the arc of the main process. So the TIG process creates very high-quality, spatter-free weld seams.
                • Laser Weld - High welding speed and excellent weld quality

                • Laser Weld creates a restricted arc characterised by a every high energy density. This energy melts the material and allows welding. The specific contact- and thus force-free energy input in the base material results in high welding speeds and high-quality welds.
                • Laser Hybrid Weld – As efficient as never before

                • The laser beam MIG/MAG Hybrid process is the combination of a laser beam with a MIG/MAG welding process in one common process zone thus using the advantages of both processes. Considerable savings in production time and filler material are possible. Full-depth welds can be welded without preparation. Moreover a high weld speed can be reached when welding either thin plates or thick plates. Due to the combination of the two processes many additional parameters can be set. Thus the process is perfectly matched to the respective task.
                • Plasma Cut - Perfectly suitable for robot applications

                • In the case of Plasma Cut the electric arc generates a plasma jet which is very restricted by a special nozzle and a focusing gas. Due to the high thermal arc energy and the high kinetic energy of the additional plasma gas the metal melts and is removed out of the cutting groove. The main advantage of this process is a very small heat-affected zone, a very good cutting quality and a high cutting speed. Due to the low heat input the component distortion is reduced to a minimum. The Plasma Cut process is perfectly suitable for welding automation.
                • Laser Cut - Excellent cutting quality at extremely high speed

                • The Laser Cut process strongly restricts the arc and generates a small focussed spot with a very high energy density. This energy melts the material and due to the kinetic energy of an additional cutting gas the molten metal is removed out of the groove. Laser cutting is characterised by an excellent cutting quality, an extremely high cutting speed and a very good automation capability. Depending on the requirement different laser types with different characteristics can be used.
