Siemens welds faster
In order to weld large gas turbines faster, in October 2008 Siemens invested in an innovative robot welding plant. The success is very impressive: the CLOOS welding robot reduced welding times from 114 to 80 hours. Moreover the rework dropped clearly by over 10%. „After ten welded linings for the turbine bearing housings, we know that we have made the right decision with the CLOOS technology”, sums up Jerry Klopf, manager of the Housing Production in the Siemens factory in Berlin. “With the core competencies of welding technology plus robotics, CLOOS has placed itself in a very good position and proved itself as a reliable system partner”.
MAG process for firm stainless steel connections
Fillet and V-seams are usually welded in three layers in the MAG process. In order to achieve the optimum results in this arc welding process, the melting welding wire is continuously fed according to the weld form and the weld speed via the CLOOS-Duo-Drive at changeable speed. A tactile sensor secures the beginning of the seam. “And an arc sensor ensures the seam tracking and controls the weld head so that we do not have to exert ourselves any more for the preparation of the seam and the width of the gap”, emphasises Jerry Klopf.
of the robotic welding system
- Welding robot type 350 fitted on 10m high C-column
- Maximum flexibility due to six movement axis and turn-tilt table
- Dynamic servo drives guarantee high load bearing capacity of 15kg
- High repeat accuracy of under 0.1mm
