BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram schematically showing an electric welding apparatus 1 including a known electronic apparatus 2 having control and output electronics for electric welding; An electrical connection can be made by the welding cable 3. With a welding device 1 of this kind, a welding connection between a fitting or a joint and a plus-tip tube can be performed, especially in a pipeline system made of thermoplastic plus-tips. In this case, current is supplied via the welding cable 3. Furthermore, welding devices of this kind make it possible to carry out the welding of plastic plates or plastic foils, for example for sealing buildings or dumps. The welding device 2 has a processing device 4 and / or a reading device 5 and a storage device 6 for processing relevant welding data such as temperature, type indication, welding current, voltage, welding time and the like. The reading device 5, like the plug or connector 7, is arranged at the end or the end region of the welding cable 3 so that data recorded on a data medium such as a fitting or a joint can be read. The data medium fixed to the fitting or the like is configured as a barcode, a magnetic card, a microchip, or the like. The parameters characterizing the welding process are stored in a storage device 6 and, if necessary, transmitted or queried externally by a data connection 8, for example a modem with a parallel interface.

According to the invention, a further receiver 10 is suitably integrated into the welding device 2 together with other electronic components in the casing of the welding device. The receiver 10 is part of a positioning system, preferably a global positioning system (abbreviated GPS), which allows accurate identification and localization of the target object using orbited satellites. To Satellite and / or terrestrial specific transceiver signals are received by antenna 12;
At the receiver 10, the exact location of the ground weld joint and / or the welding device 2 is determined. In particular, not only latitude and longitude but also sea level and time are stored. The data received by the receiver 10 is supplied to the storage device 6 and added to the data of the welding process. Thereby, the welding data, preferably stored with the job number, is at least associated with the geographical coordinates.

In a preferred embodiment, the welding device 2 comprises a data transmission system 14 by means of which other data, in particular road maps, can be loaded. Preferably, a PCM data transmission system is used. The data transmission system allows the input of additional or alternative coordinates and / or correction values, and the associated data is
Supplied to a storage device and / or computer 6.
The determination of the position can be performed mainly by the transmission system 14 in the present invention.

The data in the computer and / or storage device 6, ie welding data and position data, can be transmitted to the transfer device 16 via the data connection 8 as required. Transmission is facilitated by a cable 18 that can be connected as needed. It can also have a direct plug-in connection or a wireless transmission. The data can be stored as intermediate data by the transfer device and sent from the welding device to another computer or the like.
The transfer device 16 includes a storage medium that is writable and erasable as needed. This storage medium is in particular in the form of non-volatile storage, examples being magnetic tape, magnetic diskette, or digital storage components.
