KUKA KR 8 R2100-2 arc HW robotic welding station was built in 2021 in
Germany by KUKA Deutschland GmbH. The system is designed for precision
welding of workpieces with even the most complex geometry. All the
necessary components are integrated inside the modular design,
enabling the workstation to be adapted accordingly to current
production needs.
The workpiece welding process is performed by a KUKA 6-axis robot from
the KR CYBERTECH ARC series. The machine is distinguished by its
compact design, which provides a high degree of movement freedom even
in hard-to-reach places. To avoid any collision of cables with other
station components, they were routed inside the robot arm. All this is
complemented by an easy-to-use controller with a range of additional
functions.
During automated welding, dynamic and accurate feeding of the welding
wire is very important. To achieve this, a reliable KEMPPI feeder is
mounted directly on the machine body. The torch, in turn, is
continuously cleaned by the ABICOR BINZEL cleaning station, which
injects a special anti-adhesion substance into the torch. The cleaning
and humidification process is performed fully automatically, at set
intervals.
The welding station is fully complete and consists of the following
components:
– robot arm: KUKA KR 8 R2100-2 arc HW
– controller: KUKA KR C4
– inverter welder: KEMPPI KempArc Pulse 350
– welding cell: Robopartner RoboArc_C3
– welding positioner with rotary table
– portable control unit (pendant): KUKA SmartPad
– welding wire feeder: KEMPPI KempArc DT 400
– torch cleaning station: ABICOR BINZEL TCS-CC
