Coach panel – Mig aluminium welding
Plant for welding the aluminium panels of the coach trains.
The manipulator, with height adjustable boom (non-retractable ones), works both on the left and on the right side on jigs located parallel to the track on which its motorized base moves.
On the boom have been installed : one motorized carriage and a motorized vertical slide to deliver x/y axis of the IG tactile tracking system. The wire feeder is housed on a/m carriage in order to have a short torch sheath, whereas power source with chiller and fumes aspirator are properly located on the manipulator base.
Underneath picture Nr. 5 shows a particular arrangement of weld ground made of carbon brushes crawling on the rail and connecting the power source to the jigs that hold the job, this avoids the frequent replacement of ground cables and improves the electrical conductivity as well.
The plant is very similar to the previous one described above but, in that case, the torch
is equipped with IG 2D joint tracking system and can rotate to perform longitudinal and transversal welds.
The control panel hangs from the boom tip where the operator can stand and effectively surveys and programs the welding process.
