摘要:
A device for centering and clamping tubular parts such as conduits designed to form pipeline pipes of the type consisting of an elongated cylinder comprising in particular a clamping device, such as at least clamping shoes arranged over its entire periphery and adapted to be radially mobile projecting from said cylinder to be urged to press against the walls of the conduits to be clamped as well as means for moving each of the series of clamping shoes between a position projecting from the cylinder and a position wherein they are retracted into the cylinder

The invention relates to an orbital carrier (2) for a device for butt-welding pipes (C, C) to form a pipeline, said device comprising at least one welding carriage (1) supporting at least one welding head (6) which has at least one welding torch, said orbital carrier (2) surrounding the pipes (C, C) to be welded and being designed to enable positioning and movement in the plane of the joint between the pipes (C, C) of said welding carriage or carriages (1), and said orbital carrier (2) also being movable translationally along the pipeline as it grows. The invention consists in the fact that said orbital carrier (2) consists of at least two components (20) in the form of segments of a circle able to be connected together to form the orbital carrier (2) around the pipes (C, C) during a welding phase and also to allow said orbital carrier (2) to be opened, at least at the top, to allow it to pass an obstruction on the outside of the pipe (C, C). Application: the welding of pipes (C, C).
摘要:
The present invention concerns an automatic welding device of MIG/MAG type consisting of at least one carriage holding at least one welding head comprising at least one torch (1) guiding a consumable electrode wire along a parting plane (P) between the pipes to be welded, which brings the current to the end of the electrode wire in order to generate an electric arc and ensure melting of the filler metal,The invention consists of the fact that the welding head therefore presents a welding torch (1) intended to be centered in relation to the parting plane (P) to ensure the penetration pass and also bears at least two other so-called tracking welding torches (2, 3), respectively positioned one after the other following the first so-called central welding torch (1) and offset respectively on both sides of the so-called central torch (1) in order to make lateral passes.
摘要:
A mechanical system for automatic guiding of one or more torches of a welding unit in a groove delimited by chamfered end surfaces of two metal parts to be welded together, including a main carriage moving along a stationary guide relatively parallel to the groove, a secondary carriage that is connected to the main carriage by a hinged linking assembly and that includes a torch supporting unit and a guiding device including bearing members in contact with the surfaces of the metal parts bordering the groove and sensing members that enter the groove. The hinged linking assembly includes three pivoting axes.
