"Device for joint welding by jf

Hollow bodies ". | The invention relates to a device for g Mechanical joint welding of hollow bodies «it |

run one or more at the same time or one after the other

same or different welding processes, §

With the known welding processes by hand, the post |

part given that especially when welding hollow - |

do not equally embody the demands for high |

Welding performance with constant weld seam quality after- 1

can be come. |

In addition to the so-called manual welding processes are also mechanical welding processes and devices are known for this purpose but with which only a single welding process can be carried out. This is the The area of application of such machines is limited. The weld seams produced with the known devices correspond not always the demands placed on them.

The object of the invention is to provide a device to create joint welding of hollow bodies with

the same or different at the same time or one after the other Smoldering procedure in the case of high smoldering exposure mad of constant weld seams can.

To solve this problem, it is proposed according to the invention, daft, depending on the same or different wall thickness, the feil * welded together optionally old one or more torches either using the Wolfraa Inert Gas (TIG) process without filler material via an I-shock or old metal inert Oat - metal active gas (MIG / MAG) process in one or more 0 · 1 steps via an I-substance or different Pugenforften or in the root position or the joint with the deft WlG method without additional etching material and the subsequent layers ftit deft MIG / MAG process with and without welding gap adjustment, fully mechanized and / or program-controlled under change the welding parameters can be welded.

D · a high welding performance with constant welding strength «Ltcll ^ a, it is successfully suggested that the welding torch optionally in one place The angle of the plane to the welding point can be adjusted and the welding position to the workpiece can be adjusted to 560 ° and at the same time swivel out of this uncomfortable level and can be moved parallel to this.

The single or multi-layer welding takes place via a control element «, preferably cam lobes or the like, the de » Assigned to the respective smoldering process and assigned to this < st last sii & d.

The quality of the tail seam largely depends on how the welding gun is oriented towards the seam to be welded siadi. It is. therefore, for the purpose of aögexalrfc to be assigned to the burner 1; ell «. In further training

Design of the invention is therefore struck, the weld Kittels a movable stop as well the end face distance of the one to the other to be smoldered Parts by Axiai-Verichiebea one or both clamping points for the work · tueJc adjustable.

The device according to the invention is followed by one Embodiment specifically for pipe welding in more detail described.

Fig. 1 shows a world-wide schematically a longitudinal section

by the device according to the invention, FIG. 2 is a section along line H-II of FIG. 1.

The device according to the invention for *. Joint welding of pipes consists of a tensioning and drive machine (l) ■ with cam disk control (2) and a complete, ni-.ht illustrated, TIG-Jid MIG / llAG-inert gas welding line and the A »» ngj> iia-ri * mn control- usd special switchgear. The system is rounded off with pipe registers, infeed and outfeed roller conveyors, and trestles for the welded-together pipe strings.

In the clamping and driving machine, the pipe ends to be welded (3) {*) are clamped centrically in two manual or quick-release chucks (5) each. Both tubes are driven by a continuously adjustable DC motor (6) with reduction gear (7) and double wheel drive {&). Welding speeds of, for example, 30 to 800 mm / min, at full torque, can be set for all possible flange dimensions.

The construction of the device according to the invention is such that the control and special switching and switchgear devices, apart from the two switchgear devices and the accessories, are arranged in a way that is easy to operate. The machine

frame (9) is mounted on a »base frame (10) and supports the two symmetrically arranged bearing structures ten (11).

The bearing superstructures (11) hold the associated work spindles (13) in their bronze sliding bearings (12), bit the chucks (5) which are flanged on in mirror image. Chucks (5) and work spindles (13) are so designed that pipes can be welded in a larger »offshore area, depending on the design. Longer non-productive times for building a new pipe dimension do not occur. The bronze sliding bearings (12) provide a particularly good transition to the earth cables. A resilient support roller (14) for the infeed and outfeed roller conveyor is attached to both sides of the machine frame (9).

DC motor (6), reduction gear (7) and cam disc control (2) are mounted on the base frame (10) and with the double wheel drive (8) is machine

The TIG (15) and MIG (16) micro torches are fixed in a clamp ?, (l?), Rotatable in several axes and adjustable in all welding positions with watch holders (18). For the Robrabeessimg to be welded, the burners (15) and (16) are fixed in the determined positions by small screws (19). J> ex distance between the torch - dJäseü (20) to the workpiece (3/4) is set on both torches using a toothed rack (21).

When the tubes (3) and (4) to be welded are clamped in place, a stop (22) is raised from the machine frame {9} by foot actuation. It has the effect that the welded horns are always in the plane of the fixed mascain burner (15/16). Bas in the right clamping head {23) inserted 5onr (3}

is pulled through to the raised stop (22) and clamped. After releasing the actuation, the stop falls back into its starting position. The second pipe (4) will! pulled through the left clamping head (24), attached to the already clamped pipe (5) and also clamped. In the left clamping head (24) according to the invention a gate direction built in, which after clamping the drill (3) and (%) required an exact setting ües Distance between the web or the stira surface allows. By moving the work spindle (13) with the chucks (5) can be a Distance between webs and faces of, for example, 0 to 5 Mi can be set.

The shielding gas welding devices are commercially available devices and rectifier old additional special circuits stm Controlling the welding current.

The inventive device for welding hollow bodies is in terms of the control organs, preferably Koekenscheiben control, the special circuits of the inert gas welding equipment and the control units, coordinated with one another so that the following work processes are calibrated:

The pipes to be connected can e.g.

a) old the TIG process without filler material in the butt joint,

b) ait of the MIG / MAG process in the root, middle and Top layer,

e) in the root pass or lsi joint with the TIG process,

without filler material, and in the middle or top layer ■ with the MIG / MAG process

be welded.

Pipes up to a certain wall thickness are provided in the butt joint with an I-seam preparation. For the pipe
