Abstract

The invention relates to a method for assembly of pipes (1) and fittings (2), wherein prior to the welding outer ends of pipes and fittings are provided with a weld preparation in the form of a chamfering (3) and an upright edge (4), and wherein during an automated welding process a weld is then realized between two pipes or between a pipe and a fitting or between two fittings.

Description

Method and system for assembly of pipes and fittings
The invention relates to a method for assembly of pipes and fittings, wherein an outer end of a first fitting or pipe and an outer end of a second fitting or pipe are in each case placed precisely against each other and wherein the outer ends are then welded together in an automated welding process. Such a method is described in for instance patent application WO 95/34400. The fact that the welding process is automated may create the impression that less professional skill is required for assembly of pipes and fittings. This is certainly the case for the actual welding process, but professional skill still plays a large part in the preparation thereof. It is more specifically the case that the undefined shape of the edges of these outer ends can adversely affect the result of the welding process. The method according to the invention obviates this drawback to a significant extent and has the feature that, prior to being placed against each other, the outer end of the first fitting or pipe and the outer end of the second fitting or pipe are provided with a weld preparation in the form of a chamfering or in the form of a chamfering plus an upright edge. The welding process can then be performed in two steps, wherein in a first step the edges are welded through and wherein in a second step the combined chamferings are fully welded, this leading to a
reproducible and perfect result.
A favourable realization of the inventive method, wherein the tolerances in the dimensioning between the outer ends of the fittings can moreover be improved, has the feature that each fitting or pipe is mounted on an adapter and placed on a milling machine or grinding machine, after which the milling machine or grinding machine provides each outer end of the fitting or pipe with a weld preparation.
A further favourable realization, wherein the relative position of the outer ends is also precisely determined, has the feature that the adapter can be mounted in a discrete number of different positions on the milling machine or grinding machine. This means that, for instance after welding a T-piece between the outer ends of two pipes, the pipes will lie precisely in line with each other, while the third pipe will lie precisely perpendicularly thereof.
A further favourable realization, wherein the adapter is advantageously utilized for precise positioning of a fitting against the outer end of a pipe or fitting, has the feature that, prior to a first fitting or pipe being welded to a second fitting, an adapter and the second fitting mounted thereon are placed on an adjustable support such that an outer end of the first fitting or pipe and an outer end of the second fitting are
precisely connected together. A welding robot can then be placed around the first fitting or pipe, and the first fitting or pipe can be welded to the second fitting. The invention also relates to a system for assembly of pipes and fittings, comprising an automatic welding machine for filling a weld between an outer end of a first fitting or pipe and an outer end of a second fitting or pipe. According to the invention the system also comprises a milling machine or grinding machine for providing the outer ends of the first fitting or pipe and the second fitting or pipe with a weld preparation, wherein the weld preparation comprises a chamfering or a chamfering plus an upright edge on the outer end.
A favourable embodiment has the feature that the system also comprises adapters provided with mounting means for mounting a fitting in the adapter. The adapters can then be mounted on the milling machine irrespective of the type of fitting. The adapter is preferably provided with first positioning means and the milling machine or grinding machine is preferably provided with second positioning means which can co-act with the first positioning means such that the adapter can be mounted in a discrete number of different positions on the milling machine or grinding machine. It can hereby be achieved in simple manner that, in the case of for instance a T-piece, two outer ends are positioned perfectly parallel after the milling or grinding, while the third outer end is positioned perfectly
perpendicularly thereof. The dimensions of the milled or ground adapter are now moreover precisely known, whereby the end result of the welding operation is precisely known .
A further favourable embodiment has the feature that the system also comprises a support on which an adapter can be mounted. The support can here be adapted such that an adapter can be mounted thereon in simple manner, irrespective of the type of fitting.
A further favourable embodiment has the feature that the support is provided with a positioning member and with a ball joint so that a milled outer end of the fitting can be positioned in precise and stable manner against an outer end of a pipe. A further favourable embodiment has the feature that an adapter for a fitting is provided with an aligning member for the purpose of indicating a direction of an outer end of the fitting. It is then possible when positioning for instance a T-piece against the pipe to precisely verify the direction of the outer end of the T-piece positioned perpendicularly of the pipe, and the direction can be easily corrected using the ball joint. A laser can for instance be arranged for this purpose in the adapter or in a base plate on which the adapter is mounted and which forms part of the support . A temporary mounting can then, as is usual, be arranged between the first fitting or pipe and between the second fitting or between the first fitting or pipe and between the adapter in which the second fitting is received, after which the welding robot can be placed.
The invention will now be further elucidated with reference to the following figures, in which: Fig. 1A shows a cross-section of a prior art pipe and a fitting to be welded thereto;

Fig. IB shows a cross-section of a pipe 1 and a fitting 2 according to the invention to be welded thereto, wherein the outer ends of fitting 2 are provided on both sides with a weld preparation in the form of a
chamfering 3, which results in a welded joint of better quality when pipe 1 and fitting 2 are welded together. According to the invention both outer ends of fitting 2 are arranged in a milling or grinding process in a manner such that the end surfaces lie precisely
perpendicularly of each other, while tolerances of fitting 2 can also be improved if desired.
Fig. 1C shows a cross-section of a pipe with an
alternative fitting according to the invention to be welded thereto, wherein the outer ends of fitting 2 are provided on both sides with a weld preparation in the form of a chamfering 3 plus an upright edge . Upright edge 4 is first welded through by a welding robot, after which the chamfering is fully welded, this resulting in a superior welded joint. According to the invention both outer ends of fitting 2 are arranged in a milling or grinding process in a manner such that the end surfaces lie precisely perpendicularly of each other, while tolerances of fitting 2 can also be improved if desired. The weld preparation on pipe 1 can be arranged by the manufacturer of pipe 1 or can be arranged in a milling or grinding process .
Fig. 2 shows a possible embodiment of an adapter 5 according to the invention with which a fitting 2 can be clamped and subsequently mounted on a table of a milling machine. Adapter 5 consists of a base plate 6 on which a fixed clamping part 7b and a movable clamping part 7a are provided, as well as a locking 8 with which adapter 5 can be closed. Before adapter 5 is closed, the two end surfaces of the fitting are positioned substantially perpendicularly of base plate 6, for instance using a set square. Base plate 6 is further provided with register holes 9 with which it can be fixed to the table of a milling or grinding machine such that an end surface lies substantially perpendicularly of a milling or grinding member which forms part of the milling or grinding machine and which must arrange a weld
preparation at an outer end of fitting 2. The desired precision can be realized in simple manner by arranging for instance two register holes for each outer end of fitting 2. Fig. 3 shows an alternative embodiment of an adapter 5 according to the invention with which a T-shaped fitting 2 can be clamped and subsequently mounted on a table of a milling machine. Adapter 5 consists of a base plate 6 on which a fixed clamping part 7b and a movable clamping part 7a are provided, as well as a locking 8 with which adapter 5 can be closed. Before adapter 5 is closed, end surfaces of the fitting which do not run parallel are positioned substantially perpendicularly of base plate 6, for instance using a set square. Base plate 6 is further provided with register holes 9 with which it can be fixed to the table of a milling machine such that an end surface lies substantially perpendicularly of an end mill which forms part of the milling machine and which must arrange a chamfering at an outer end of fitting 2. The desired precision can be realized in simple manner by arranging for instance two register holes for the three outer ends of fitting 2. Fig. 4 shows a schematic side view of a milling or grinding machine according to the invention, with a table 10 provided with register pins 11 so that an adapter 5 can be placed accurately in predetermined manner in front of a main plate 12. A carousel 13 which, using a motor 14, can rotate around an axis 15 is mounted on main plate 12. Mounted on carousel 13 is an adjustable carriage 16 on which a motor 17 is mounted, which drives a milling or grinding member 18 which provides the chamfering on the outer end of a fitting with a weld preparation via an opening 19 in main plate 12. Milling or grinding member 18 can take a form here such that the end surface part of fitting 2 is also milled off, whereby fitting 2 obtains a predetermined standard dimension.
Fig. 5 shows a schematic side view of a support 20 according to the invention, provided with a height adjustment 21, a longitudinal transport 22, a transverse transport 23, a ball joint 24 provided with an arresting member 25, and provided with a base plate 26 provided with register pins 11 on which an adapter 5 can be mounted. An outer end of a fitting 2 present in adapter 5, for instance a right-angled bend, can now be placed accurately against an outer end of a pipe. The free outer end of the right-angled bend has then yet to be aligned in a direction in which the pipeline must continue its path. Base plate 26 is provided for this purpose with an aligning member 27, in the embodiment shown here a laser, which precisely indicates this direction. Alignment can now take place using ball joint 24, after which ball joint 24 is secured using arresting member 25, after which the welding robot can carry out its work.
Fig. 6 shows schematically a temporary mounting of a fitting 2 which is mounted on an adapter 5, this in turn being mounted on a support 20 (not shown in the figure) . Adapter 5 is positioned such that fitting 2 connects precisely onto pipe 1 and that laser 27 is moreover pointing in the desired direction. A divided ring 28 is then mounted on pipe 1 and a pressure plate 29 is pulled against fitting 2 using pull rods 30a, 30b, after which fitting 2 is completely fixed and automatic welding machine 31 can be placed.
