An apparatus for welding ends of plastics pipes comprising a supporting frame (16, 116) for a first clamp (17) for locking the end of a first pipe (18) and for a second clamp (19, 119) for locking the end of a second pipe (20) to be welded to the first pipe (18); the second clamp (19, 119) movable toward the first clamp (17) with translational motion. A heat-generating element (33) for welding and a milling device (34) for the ends of the first and second pipes (18, 20) are associable with the welding apparatus (10, 100) provided with a control unit (36) and with reversible elements for fixing to a vehicle (11, 111) provided with an auxiliary hydraulic system (25). The reversible fixing elements (14) comprise hydraulic couplings (28) for connecting the auxiliary hydraulic system (25) to the hydraulic means (21) for the translational motion of the second clamp (19, 119) and to a hydraulic motor (26) which is connected to an electric generator (27) for supplying power to the welding apparatus (10, 100). |
