Installations for assembling by welding or other means comprising means for positioning the various constituent parts, at least one programmeable means for assembly by welding or other means. An installation characterised in that it comprises at least one gantry (10, 11) the upper face of which accommodates the programmeable welding or other means which can be moved on at least one mobile cross member (10.sub.1, 11.sub.1) and in that means (13, 14) are provided to move constituent parts in the lower zone of the gantry and to immobilise them under the welding means.

DETAILED DESCRIPTION We claim: 1.
Installation for assembling various constitute or subassembly parts, said installation including: at least one programmable welding robot; a transfer line having a plurality of consecutively arranged stations spaced apart by equal distances with each of the distances corresponding to a predetermined length dimension; at least one gantry having a length corresponding to said predetermined length dimension for forming part of one of said station, said gantry including an upper elevated frame with at least one horizontally movable cross member supporting said programmable welding robot for vertical movement of the robot relative to the cross member; a base movable transversely of said transfer line into and out of a lower part of said gantry below said elevated frame, said base carrying positioning members for said parts; transfer bars extending along the plurality of said stations of said transfer line for carrying a subassembly to said gantry for support by said base; and means for lowering said transfer bars to place said parts on positioning members of said base by lowering of said bar when the base is in the lower part of said gantry.
2.
The installation according to claim 1 further including a second gantry having a length corresponding to said predetermined length dimension, said at least one gantry and said second gantry being detachably linked to respective consecutive ones equal distant support structures.
3.
The installation according to claim 2 further including a second programmable welding robot; and wherein said second gantry includes an upper elevated frame with at least one horizontally movable cross member supporting said second programmable robot for vertical movement relative to the cross member.
4.
The installation according to claim 3 further including a second base movable transversely of said transfer line into and out of a lower part of said second gantry below the elevated frame thereof, said second base carrying positioning members for said parts
