Typical welding robot system applications -

Small-scale - compact systems

The robot is mounted on a support in an upright position. The platform is shared with the workpiece periphery enabling 2-station operation for economical welding of small workpieces.

The entire robot installation may be installed on a stable platform for easy assembly. The seven basic modulARC components may be combined in a number of ways to form different manipulator types including position or NC-controlled axes.

Robot welding cell modulARC Robot working area: ø 2,5 m Handling device Load capacity 150 kg (335 lbs.) per station Number of stations: 2 Face plate distance: 1,5 m

Medium-sized - Floor-mounted track systems

The robot is mounted on a vertically adjustable articulated bracket which can be moved along a floor-mounted track in a longitudinal direction. Including the manipulator, 11 axes are simultaneously controlled. The hollow shaft of the face plate with the corresponding fixture allows the robot overall access. Thus, the entire excavation chassis may be welded in one process.

The automatic fixtures are designed for different workpiece sizes, and the face plate of the boom is free-standing for unlimited accessibility.

Large-scale - Overhead tracking systems

Each of two robots are mounted in a hanging position on a cross- and a vertical track sharing a longitudinal track system. The robots are equipped with a torch exchange system and an opto-electronic camera system for seam tracking and volume compensation.

Complex - flexible systems with automatic workpiece loading

This fully automated production line for excavation components comprises the robot installations, corresponding loading and unloading area, buffer stations, inspection areas and two processing centers. All stations are linked by loading wagons. Workpieces are transported by satellite wagons to the stations.

The system contains a supervising computer for robot and transport systems, a bar-code reading system for calling corresponding robot programs, off-line programming, process visualization, and warehouse control.
