The KUKA KR16 L6 ARC-C robotic welding station with the PO-2t6m-01 rotary positioner was launched in 2017 and worked for a total of 50 hours. Previously, the welding robot arm built in 2009 was used only for testing. The entire welding station has been specially designed for very precise welding of gates and fence spans, but it can also weld various types of structures that fit within the positioner.
The KUKA KR 16 L6 ARC-C robotic welding system is equipped with:
– robot arm: KUKA KR16 L6 ARC-C
– controller: KUKA KR C2
– software: KUKA System Software (KKS)
– current source: FRONIUS TransPuls Synergic 4000 CMT R
– wire feeder: FRONIUS ROBACTA DRIVE CMT
– burner cleaning device: TBi BRG-2-ES-DAE
– rotary positioner: PO-2t6m-01
– track
The track-guided KUKA KR16 ARC welding robot has a reach of up to 6 m and a robust arm with 6 dynamic axes driven by an electromechanical system with brushless AC servomotors. High axial speed combined with small dimensions and weight guarantee excellent precision and the highest quality of welds, even in hard-to-reach places. The robot is controlled by a KUKA KR C2 controller with many useful functions, which significantly increases the productivity and efficiency of the machine.
Directly on the body of the welding torch, the FRONIUS ROBACTA DRIVE CMT feeder is mounted, which supports all welding processes by very dynamic and precise feeding of the electrode wire. The torch of the machine is cleaned of impurities by the TBi BRG-2-ES-DAE cleaning device, which cuts off the end of the wire, sprays anti-spatter liquid on the torch head in a closed spray chamber and removes spatter by a rotating reamer.
The PO-2t6m-01 manipulator has been adapted to rotate elements with a maximum weight of 2 tons and a length of 7 meters, in order to make welded joints. The turntable consists of a connector, a gear motor, a reaction arm, a control cabinet, a sensor mounting assembly and two bodies made of welded sheet, in which the positioner shafts with bolted discs are placed. A rotary table is attached to the discs, centered with pins inserted directly into the holes in the bearing shafts.
