Problems solved by technology

[0007] A disadvantage of the electric welding sockets known from the prior art is that a sufficient connection cannot be established between the pipe and the electric welding socket when the pipe is not sufficiently inserted into the electric welding socket
This results in leaky tube connections
In addition, tubes that are not inserted sufficiently in the welding sleeve can cause localized overheating of the welding sleeve, which can even lead to fire in the worst case
The display for checking the correct positioning of the individual elements relative to each other is only insufficiently provided in the welding sleeves known from the prior art

Abstract

The invention relates to a method for connecting a thermoplastic line element (3) to a connecting element (2). The method comprises the following steps: providing the at least one thermoplastic line element (3); providing the connecting element (2), which has a thermoplastic body (4), wherein there is embedded in the body (4) a heating element (6), which serves for generating heat for welding the body (4) to the at least one line element (3) in a welding region (5); joining the connecting element (2) to the at least one thermoplastic line element (3); providing a welding device (10) for welding the connecting element (2) to the at least one thermoplastic line element (3); welding the connecting element (2) to the at least one thermoplastic line element (3) by generating heat in the welding region (5) by means of the welding device (10). The welding of the connecting element (2) to the at least one thermoplastic line element (3) is stopped by the welding device (10) before the end of the planned welding time if a fault criterion is met.

Description

technical field [0001] The invention relates to a method for producing a welded connection of a conduit element and a connecting element. Background technique [0002] The connection of conduit elements made of thermoplastic by means of likewise thermoplastic connecting elements provided with heating elements is known. Conduit elements are understood here to mean pipe components, fittings and shaped parts which are joined via connecting elements to form conduits and conduit networks. The connecting elements are often designed here as welding sleeves and welding-able connection and drilling jigs. However, connecting elements can also be used to connect other elements than pipe elements, for example for joining rods, but the use of weldable connecting elements in pipe construction is one of the most common fields of application. In order to reliably connect conduit elements by means of such connection elements, it is desirable to check the weld. The starting point of EP 017...
