Plant for welding the frame and the roof of high speed trains.
A gantry moves on rails with a work volume of 66 m length x 4.5 m width x 1.2 m height.
Its crossbeam height is automatically adjustable and four motorized carriages are installed on it, each carriage equipped with diving boom stroke 1200 mm.
The 2 diving booms lower end is equipped with automatic MIG welding torches both provided of an IG SCAN and of video systems as well and both handled by 2 – axis zero backlash robot wrists whereas automatic brushing machines are carried on by the other pair of diving booms.

A 16-axis CNC allows to enter countless jobs – each one including the brushing and the sequence – and parameters welding as well.
