Innovative highlights shown in arc
welding
Cold process arc welding - to be demonstrated in a turnkey robotic system - reduces component distortion and the burn off of a coating when welding coated plate assemblies.
In Hall 13/Stand D 33 of the EuroBLECH 2006 trade fair, Carl Cloos Schweisstechnik, D-Haiger, will be presenting a number of product innovations in welding machine and robotic technology as well as highly efficient process technologies The new CP process (Cold Process) developed by Cloos for efficient thin-plate welding is presented in a turnkey robot system

Robotic arc welding developments exhibited
A turnkey, easily transportable Z6 robot welding cell for universal applications will be shown at Automatica as well as the latest synergy-controlled pulsed arc welding machines.
Digital drives shorten robot acceleration times
Digital drive technology guarantees short acceleration and delay times, as well as excellent robot dynamics, feature industrial robots for a variety of production line tasks.
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.
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 will be welded here.
Other advantages of CP are the optimised gap bridging ability and the considerably increased welding speed of about 50% - particularly when welding aluminium.

Pulsed arc welders offers stored expert knowledge
Using efficient 'Variable Synergic Mode' in fully digitised pulsed arc welding machines enables the use of stored expert knowledge via a single knob with the option of individual parameter setting.
Programmed MIG and TIG settings changed manually
It possible to manually correct individual welding parameters, without changing the original working program, in this compact universal arc welding power source for MIG and TIG.
Robotised MIG tandem brazing joins thin plate
MIG Tandem brazing using industrial robots is a highly efficient joining procedure especially for refined thin plate, but also can be used for uncoated as well as low- and high-alloy steels.
Time-consuming rework is no longer necessary due to the extremely reduced spatter formation.
The 6-axis Romat 320 industrial robot is equipped with an automatic tool change system and demonstrates 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.
MSG laser hybrid high-capacity process, an efficient combination of laser beam and arc welding, will be 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.
Robotic systems - the versatility of the Romat robot technology in the field of welding and handling is shown by two co-operating industrial robots.
The new Romat 400 is designed for a carrying capacity of up to 30 kgs 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.
* Pulsed-arc welding - at this exhibition a fully digitised HighEnd pulsed arc welding machine, which has been specially designed for the requirements of the automotive industry, will be 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 3rd 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.
* Robot welding torch - a 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 being presented at this exhibition.
