    Abstract: Tube elements, i.e. pipes, shaped pieces and armatures of weldable synthetic material, are interconnected by electric welding. The welding operation is made possible by means of a welding sleeve (3) which is connected to the output (4) of the apparatus. A monitoring device (11) allows the engagement of a stage (7) of the welding circuit. The heating power is determined by a quadratic mean of the welding voltage of the network voltage respectively, in a pulse generator (9) which generates a pulse frequency depending upon this value. The generator pulses are added in a counter (10) and when the counted value corresponds to the heating energy, the stage (7) of the circuit is disengaged. If this value is not reached, a monitoring device (5) produces a failure signal.

    Abstract: The invention concerns a device for welding an accessory (10) on a pipe (11) made of thermoplastic material. The accessory (10) comprises segments whereto are integrated electrical heating elements powered by a welding apparatus (1), via electrical connecting lines (21, 22), thereby enabling to assemble the pipe (11) and the accessory (10) by welding at their mutual contact zones. The welding apparatus electrical connecting lines (21, 22) comprises mutual coupling elements (28, 29) which can be placed in electrical contact with the coupling elements (18, 19) located on the accessory segments. In order to obtain a perfectly welded assembly with low consumption of energy, each of the two welding apparatus (20) connecting lines (21, 22) is connected with its respective connection line (31, 32) so as to obtain each time a combination of lines (30, 30'). The two line combinations (30, 30') comprise in turn two mutual coupling elements (18, 19) of different segments of the accessory (10), thereby producing a parallel electrical connection of all the heating elements located in the accessory (10).
