igm Robotersysteme AG at Schweißen & Schneiden 2009

igm Robotersysteme AG presented a number of new developments on occasion of the exhibition Schweissen und Schneiden in Essen:

• Robot RTi 390: the new developed mechanics, featuring in an enlarged working diameter of 4.600 mm and significantly faster axes speed
• Power Source iARC 5000: igm’s new power source for MIG/MAG welding processes with 500 A at 100% DC
• Welding media transfer: optimised hose package and improved wire liner
• Bevelling system iBS: redesign igm bevelling system with robot control RCi, teach pendant K5 and cutting parallelogram
• Laser camera iCAM: application on welding robot for seam tracking and gap detection, for the first time on the iBS for edge tracking
• Offline Teaching: programming of igm robot system via PC with original teach pendant K5

6 Days in the Focus of Welding Technology

The exhibition Schweißen & Schneiden (welding & cutting) is representing every four years the major platform for everybody being involved in this branch for getting informed about the latest developments and future aspects. Despite of the economically turbulent times the number of visitors was again very satisfying, even though it could be expected to be higher. Supposing some money saving tendencies of companies, there could be stated a positive aspect: rather high level managers and owners visited the fair, pushing up again the quality of the contacts made.

 
However, the visitor traffic was impressive: we could register sales leads from 43 countries world wide; with some of them we had interesting and detailed discussions. Of course we highly appreciated to welcome already existing customers and business friends, who took the opportunity of this come-together for informal but informative chats.

Exhibit: Robot System for Welding of Rear Frames

A large scale welding robot system for sensor controlled welding of rear frames was one of the main exhibits. The column was assembled to a rotary module; a cantilever arm has been travelling on this column carrying the welding robot RTi 330. The work piece was taken up by an L-shaped manipulator with a payload of 3,000 kg. The Laser camera iCAM was shown with its functionalities joint-tracking and adaptive control of the welding parameters.

Exhibit: Robot System RTi 390

The new welding robot generation RTi 390 has been showcased to the public in occasion of the Schweissen & Schneiden 2009. It is not only the working enveloped enlarged by 200 mm, which significantly improves the accessibility of the robot in upright position, important changes have been carried out with drives and media guiding: e. g. the hose package can be changed without any tools. For the first time in public, the new igm welding power source iARC 5000 has been presented, featuring in an admissible load of 500 A at 100% duty cycle.

Exhibit: iBS bevelling machine for sensor-guided chamfering of flat sheet metals

Apart from the rationalisation of the cutting process itself, the exactly executed chamfering inspires ideas for a rationalising of the welding process which follows. The iBS bevelling system allows the chamfering angles to be adjusted exactly and to be maintained along the whole of the plate edge. Depending on the plate thickness, the iBS is able to process to within a tolerance range of +/- 0.5 millimetres. What would be scarcely imaginable for practical purposes in a manual chamfering context the machine can manage with ease: the chamfering angle can be continuously varied in the automatic processing of a work piece. Quite apart from this, a chamfering of bent and circular contours is possible. The iBS machine chamfers internal and external contours - and apart from this it is possible to cut funnel-shaped holes, e.g. in machine components made from thick metal plates.

 
The new version presented is controlled via the well-proven igm teach pendant K5, the igm developed laser camera iCAM is applied for online edge tracking.
