1. A device for mutually positioning a first tube relative to a second tube, comprising:
a cramp including first and second homologous flanges mounted one on the other, the first flange supporting a first set of hydraulic jacks, the first set of hydraulic jacks being configured to allow a relative displacement of an end of the first tube, and the second flange supports a second set of hydraulic jacks, the second set of hydraulic jacks being configured to allow a relative displacement of an end of the second tube, the jacks of the first set of jacks and of the second set of jacks each being associated with a solenoid valve that can be controlled to supply the jack with fluid and with a proportional-type pressure regulator which can be made to control output of the jacks; and
a computer,
wherein each jack of the first set of jacks is associated with its own solenoid valve,
wherein each jack of the second set of jacks is associated with its own solenoid valve,
wherein the computer is configured to individually and independently control each solenoid valve associated with its respective jack, and
wherein each jack has an internal movement sensor connected to a central control and processing unit capable of transmitting corresponding data to the computer in order to move and/or deform the first tube and the second tube so as to obtain optimal coincidence of end surfaces of the first tube and the second tube for the purpose of welding the end surfaces of the first tube and the second tube.
