摘要:
The present invention is directed to a system for welding together segments of a pipeline. The system includes an external alignment mechanism for externally supporting and manipulating the orientation of pipe segments in order to align relative segments. The system also includes an internal welding mechanism for applying a weld to an interior face joint of the two abutted pipe segments. The internal welding mechanism including a torch for applying a weld, a laser for tracking the weld profile and guiding an articulating head of the torch, and a camera for visually inspecting the weld after the weld is applied.

The invention relates to a method for producing shell-and-tube heat exchangers, consisting of collector tubes, arranged at a distance from one another and running substantially parallel to one another, and a plurality of cross tubes, the ends of which are welded to prefabricated connecting holes of the collector tubes or which are connected to one another by means of welding and using U-shaped tube bends, a metal inert-gas welding with a torch that has a non-consumable electrode and with the addition of a welding filler being used as the welding method, and also relates to a device for carrying out the method. The invention is based on the object of simplifying and automating the entire welding of shell-and-tube heat exchangers. This is achieved according to the invention by the welding device being divided into two individual units, that is the torch on the one hand and the welding wire feed on the other hand, by the two individual units being fastened to separately controllable robot arms, by the torch being moved by means of its robot arm continuously around the welding location by 360° or somewhat more in a single operation and by the welding wire feed being moved by means of its robot arm in such a way that it runs together with the torch around the welding location by about 180° in a first operation, then swivels around to the other side of the torch by about 360°, and finally moves the remaining approximately 180° together with the torch in a second operation.

Disclosed are a heat exchanger capable of simplifying a configuration and a manufacturing process thereof, and a manufacturing method of the heat exchanger. The manufacturing method of the heat exchanger includes arranging a pair of header boxes to be spaced apart from each other, each of the header boxes being formed using a single hollow rectangular pipe, and mounting a plurality of finned tubes to the header boxes such that one end of each finned tube is connected to any one of the header boxes and the other end of the finned tube is connected to the other one of the header boxes.

The invention relates to a device providing assistance in the working of pipes, including: a plate (5) having an internal cavity and comprising parts (13A, 13B, 13C) assembled together such that they can pivot to occupy a closed position in which they are joined to form a ring; and a plate locking device. The adjacent ends of two plates (13A, 13B, 13C) include corresponding surfaces that are shaped to co-operate and establish a connection as the plate (5) moves into the closed position. Each connection comprises two complementary surfaces (37) that come into contact with one another in the closed plate position. The locking device comprises at least one catch which can be actuated in said position and which acts on the adjacent ends of the plates (13A, 13B, 13C) in order to clamp the complementary contact surface against one another.

A pipe welding arrangement (10) that allows for real-time independent control of all carriages, torches, and ancillary components by design is provided. The approach uses a split-ring race that is mounted on a backing ring of similar design. Numerous welding heads (24) are mounted on carriages that are distributed at set intervals along the circumference of the race. The left and right side race and backing ring assemblies are split at the twelve o'clock and six o'clock positions. They can be decoupled and spread apart horizontally to facilitate installation and for clearing obstacles. Alignment tools (tapered pins) (32) facilitate assembly. Locking devices (20) located near each split interface, coupled with the alignment pins (32), assure that the race acts as a continuous unit during the welding operation. Linear actuators (22) mounted on the backing rings maintain concentricity between the race and the welded tube and act as a positive clamping system.

The interior of a straight pipe is clad using a plurality of welding heads. The pipe is carried on support rollers including drive components for rotating the pipe about its axis while holding it fixed against axial movement. There are four welding heads with two carried on a cantilevered support arm of a respective one of a first and a second carriage mounted outside the pipe at opposite ends of the pipe and each movable in a direction longitudinally of the axis of the pipe. The heads are located on the arm at a common angular position at bottom dead center to weld vertically downwardly. The pipe support includes a pair of drive rollers arranged with their axes parallel to the axis of the pipe and adjustable in spacing to change the height of the pipe on the rollers relative to the welding heads.
