Innovative welding technology shown at
EuroBLECH
A number of product innovations in welding machine and robotic technology as well as highly efficient process technologies - including thin plate welding.
The new CP process (Cold Process) developed by Cloos for efficient thin-plate welding is presented in a turnkey robot system A special feature of the new HighEnd GLC 353 Quinto CP pulsed arc welding machine, which is also suitable for manual applications is the very low heat input in the weld seam

Compact cell welds small parts cost-effectively
Cost-effective welding system, with all the process units mounted on a common base plate, is designed for universal application in the production of small parts.
Large robot welds 8-tonnes excavator arms
Large robot welding system with an order value of approximately EUR 1.5 million has been installed in the Belgian plant of a global manufacturer of construction machinery.
Thus the CP process reduces component distortion and the burn off of the coating is significantly reduced when processing coated plates - as with the small parts made of thin CrNi steel, which were welded at EuroBLECH.
Other advantages are the optimised gap bridging ability and the considerably increased weld speed of about 50% even particularly when welding aluminium.
Time-consuming rework is no longer necessary due to the extremely reduced spatter formation.

Among a number of arc welding innovations, Cloos will demonstrate high capacity laser hybrid laser beam and arc welding process in a special handling and welding system for the automotive industry.
Compact robot welding systems are universal
Compact 6-axis robot systems for universal application offer effective low-cost robot welding, feature computer controlled pulsed arc welding machines and a fast installation and commissioning time.
Cold process welds thin gauge metal sheet
Manual welding power sources, including a Cold Process manual welding system for the joining of thin gauge materials, will be shown at the UK's MACH 2008 event.
The 6-axis Romat 320 industrial robot is equipped with an automatic tool change system and demonstrated the efficient combination of welding and handling tasks: using a gripper the robot loads the freely programmable positioning unit and after a rapid change to the welding torch the robot welds the component using the CP process.
* Laser+arc welding - MSG laser hybrid high-capacity process, an efficient combination of laser beam and arc welding, was presented in another robot station.
The newly developed laser hybrid welding head with integrated 7th robot axis provides optimum torch orientation which ensures an easy tracking of the weld seam even when changing welding direction.
This prevents awkward welding interruptions and ensures shorter cycle times for the robot welding process.
The integrated process monitoring sensors offer excellent possibilities for realisation of the most varied seam forms in universal application.
The high laser capacity of 20kW is an advantage particularly when welding thick materials.
The versatility of the Romat robot technology in the field of welding and handling was shown by two co-operating industrial robots.
The new Romat 400 is designed for a carrying capacity of up to 30kg and together with a Romat 350 welding robot demonstrates the efficient welding of components of very different sizes.
The handling robot, which is equipped with a gripper system, moves the workpiece into the optimum welding position while the welding robot is simultaneously welding.
When the welding process is finished, another different sized component can be immediately welded without any time-consuming retrofitting or tool change.
The use of the handling robot eliminates the need for costly positioning units.
At the exhibition a fully digitised HighEnd pulsed arc welding machine, which has been specially designed for the requirements of the automotive industry, was presented for the first time for robot applications.
With a favourable price/performance ratio the GLC 353 'Automotive' welding machine offers many technical features which guarantee a high process reliability and excellent welding results even when short arc welding or MIG brazing.
Synergic operation or single parameter adjustment can be freely selected in the variable synergy mode (VSM) at any time.
Tested synergy characteristics are available which are perfectly adapted to the respective welding application.
The functions 'Low spatter ignition' and AluPlus are provided as standard.
For high flexibility in the automotive production the machine can be adjusted by an external operating unit which is located remotely from the power source at the robot work station.
The new, very compact wire drive is directly mounted on the third robot axis thus ensuring a reliable and slip-free wire transport.
The stackable housing of the 'Automotive' is space-saving and suitable for integration into all production systems.
The newly developed robot torch system FlexTorch is unique world-wide and has two additional axes in the welding torch bracket which allows optimum adaptation of the torch geometry to the requirements of the component.
The freely programmable rotating axis is integrated in the robot controller; using the tilting axis the robot can change the angle of the welding torch.
This increases flexibility in particular where there are narrow angled weld contours which are difficult to access or completely inaccessible with standard torches.
As out-of-position- welding is significantly reduced, seam quality is improved with the FlexTorch system and productivity increased when robot welding complex components.
New software products for robot welding as well as the large range of MIG/MAG and TIG manual welding machines and torch series complete the exhibits presented at EuroBLECH.
