Robotic system UDS747 for arc welding of bulky chassis constructions

UDS747 intends for MIG/MAG welding of bulky chassis constructions.

UDS747 consists of:
- Industrial robot RM-01 (PUMA-560) with the control device "Sfera-56";
- Set of welding equipment KEMPPI (Finland);
- Two-coordinate extender of robot service area;
- Four one-coordinate multiposition product manipulator;
- Assembly fixtures for welding with pneumodrive.

Peculiarities of UDS747:

Welding is run in four working places, where are, by turns, welded four units of chassis. Final welding is realized by manual device on the separate working place.
Welding product time more then 20 minutes.
Using special software.
Software of control device "Sfera-56" is updated with provision for specifics of arc welding and allows:
- a management of six coordinates of robot and two additional coordinates by extender of its service area;
- correcting a seam line by using base spots of product;
- correcting the modes of welding, arc starting and crater welding in the manner of unified operators with the possibility of programming parameters in suitable for the welder dimensionality;
- forming a library of welding modes.

Launching: In 1996.
