Equipment with welding apparatus

Technical field

The invention relates to a device with a welding apparatus by means of which the current, voltage and welding time are predetermined and stored in particular, the welding apparatus comprising a memory and / or a computer.

BACKGROUND OF THE INVENTION

An electric welding apparatus of this kind is known from U.S. Pat. No. 5,130,518 and is used, in particular, for the electric current welding of necks or fittings with thermoplastic pipes. This welding machine allows the storage of the parameters required for welding and, if necessary, printing of the welding documentation, while also allowing the transfer of data to a computer, in particular to a personal computer or laptop. This welding machine includes a computer-controlled command system for fully automatic welding control and monitoring. When laying pipes, welding of a plurality of sockets, fittings or the like is carried out, and recording and logging of the data required for welding as well as the assignment to the respective welding site requires considerable expense. There are cases where these data are not sufficient to accurately identify them. Assignment to the respective welding spot can cause a number of problems in the short term due to inaccurate data. Managing and storing the amount of data is costly, and after a short period of time the data may not be available for testing and maintenance in practice or no longer provide the necessary assurance to unambiguously assign it to a particular fitting, fitting or the like.

The positioning system may further be stored with other data, for example, a road map or drawings of the laid network, and corrected as necessary to ensure accurate positioning of the welding machine. Said data, i.e. welding data as well as position data, are preferably processed in a computer and stored in a memory. For evaluation, these data are preferably recalled via the transfer unit. and save. Thus, these data can be retrieved via the handover unit at the construction site without difficulty and, after the handover unit is transferred to the documentation center or computing center or office, stored in the computer in the necessary manner and further processed.
