The welding of the crane booms is done in 2 stations. A suspended robot travels in the XYZ direction and can operate both stations. The total length of the track is 45 m. Robotics is supported by a Panasonic TM-1800 with Arc-Eye camera system. The product weights can be up to 10 t and the length up to 20 m. The special feature of the two workstations is the central, very flexible displacement of the heavy-load positioners. The 10 t manipulators are sliding on a rail system and might be moved to a specific position depending on requirements. Various tests with software waveforms and settings were carried out in advance for the welding quality requirements. KSK received welding software adapted to their needs. This is only possible because, in addition to the Panasonic robot, we also use the power source as an integral part of the system. "I can do the off-line programming and creation of new programs very easily in the office because of the DTPS off-line software. This feature makes my job much easier," says Filippo Di Lonardo. The DTPS software also comes from Panasonic and represents a fully comprehensive welding programming solution from a single source, without having to worry about interfaces or software coordination.
