Hot plate welding, also called heated tool welding, is a thermal welding technique for joining thermoplastics. A heated tool is placed against or near the two surfaces to be joined in order to melt them. Then, the heat source is removed, and the surfaces are brought together under pressure. Hot plate welding has relatively long cycle times, ranging from 10 seconds to minutes, compared to vibration or ultrasonic welding. However, its simplicity and ability to produce strong joints in almost all thermoplastics make it widely used in mass production and for large structures, like large-diameter plastic pipes. Different inspection techniques are implemented in order to identify various discontinuities or cracks.

- Spiegellassen (Engels:mirror welding of hot plate welding) is een vormgeefproces waarbij twee delen aan elkaar worden bevestigd door ze te versmelten. Een kenmerk van het spiegellassen is dat er geen lasmiddel wordt toegevoegd. Het lassen gebeurt door de contactvlakken, nadat deze door verhitting plastisch-vloeibaar zijn geworden, tegen elkaar te drukken. Hierdoor versmelten ze. (nl)
- Das Heizelementstumpfschweißen (HS) wird nach Regelwerk DVS 2207 Teil 1 angewandt. Es dient zur Verbindung von Kunststoffrohren aus teilkristallinem Thermoplast (z. B. Polyethylen, Polypropylen, Polyvinylidenfluorid) vorwiegend in großen Dimensionen (z. B. ab 160 mm Durchmesser) und kommt ohne Fittinge und Formteile aus. Die Rohrenden werden auf Schmelztemperatur erhitzt und zur Verbindung stumpf aufeinander gedrückt. (de)

Die Rohrenden werden auf Schmelztemperatur erhitzt und zur Verbindung stumpf aufeinander gedrückt. Ein ähnliches Verfahren ist das Heizelementmuffenschweißen, das vor allem bei kleineren Rohrdimensionen zum Einsatz kommt.Im Gegensatz zum Heizelementstumpfschweißen werden hierbei Muffen zum Verbinden der Rohrenden verwendet, die vor dem Zusammenfügen gemeinsam mit dem Rohrende erhitzt werden.
