Jedoch können im einzelnen die Wärmeelemente so gewählt werden, daß sie den Arbeitsbedingungen genügen. Sie müssen nur die zur Verschweißung notwendigen Temperaturen der Werkstücke erzeugen können.However, in particular, the heating elements can be selected to suit the working conditions suffice. You only have to generate the temperatures of the workpieces required for welding can.
Dieses Verfahren eignet sich für alle schweißbaren Kunststoffe. Die im einzelnen zu verwendenden Temperaturen, Anpreßdrücke und Einwirkungszeiten hängen dabei natürlich vom Material und dessen Wandstärke ab. So beträgt die Schweißtemperatur für ein Polyäthylen mit einem Molekulargewicht von etwa 300 000 und einer Dichte vonThis process is suitable for all weldable plastics. The individual to be used Temperatures, contact pressures and exposure times naturally depend on the material and its Wall thickness. So is the welding temperature for a polyethylene with a molecular weight of about 300,000 and a density of
0,955 g/cm3 etwa 200° C. Wenn der verwendete Rohrabschnitt einen Außendurchmesser von 110 mm sowie eine Wandstärke von 3,5 mm und das einzusetzende Rohrstück einen Außendurchmesser von 63 mm und eine Wandstärke von 3 mm aufweist, muß man zum Erwärmen auf die Schweißtemperatur während einer Zeit von etwa 90 Sek. einen von 0,5 kg/cm2 bis auf 0 kg/cm2 abnehmenden Druck ausüben. Zui Erzeugung der ringförmigen Schweißzone des Rohrabschnittes benötigt man einen Druck von 29 kg/cm* während 25 Sek. und während weiterer 35 Sek überhaupt keinen Druck. Der Druck, der auf der sich beim Aufdrücken des Rohrstückes auf den Rohrabschnitt gebildeten Wulst ausgeübt werden muß beträgt etwa 81 kg/cm2, dieser muß während etw£ 10 bis 15 Sek. aufrechterhalten werden.0.955 g / cm 3 about 200 ° C. If the pipe section used has an outside diameter of 110 mm and a wall thickness of 3.5 mm and the pipe section to be used has an outside diameter of 63 mm and a wall thickness of 3 mm, you have to heat to the Welding temperature exert a pressure decreasing from 0.5 kg / cm 2 to 0 kg / cm 2 for a period of about 90 seconds. To create the ring-shaped welding zone of the pipe section, a pressure of 29 kg / cm * is required for 25 seconds and no pressure at all for a further 35 seconds. The pressure which must be exerted on the bead formed when the pipe section is pressed onto the pipe section is approximately 81 kg / cm 2 , and this must be maintained for approximately 10 to 15 seconds.
