DEMMELER commissioned large robotic welding system with 24 axes and continues to automate

"In order to further optimise our processes, we are currently automating almost all production areas", says Johannes Demmeler, managing partner. Welding technology is an important part of the production chain. The new robot welding system with a total of 24 axes enables economical production with excellent welding results.

With a total length of 21 meters, the robot welding system consists of two stations, each equipped with an 8-ton manipulator. The manipulator consistently brings the work pieces into the ideal welding position. Two Qirox QRC 350 welding robots with an interference circle of 5 meters each are attached overhead to a longitudinal- lateral- height slide system and can flexibly slide back and forth between the two stations along a 16 m long portal. In addition, the robots can also be moved horizontally by 1.5 m and vertically by 2.5 m. The large range of the two welding robots simplifies and accelerates the welding of complex workpieces. The robots can weld together on one workpiece or parallel at both stations using position detection. This increases the flexibility of the system enormously.

The welding robots also have a torch changing system for the flexible use of different welding processes - depending on the application. In addition, the system is equipped with a laser sensor, arc sensor and a tactile gas nozzle sensor: During welding, the arc sensor measures whether the torch position actually corresponds to the programmed path. Deformations of the workpiece - for example due to thermal expansion - can be compensated directly.
