The heating phase, sometimes referred to as 'bead up', is where the pipe ends are pressed against a heated plate for a period of time. This is followed by the 'heat soak' phase where the pressure is reduced to just hold the pipe ends on the hot plate. This allows time for the heat to soak into the material at the pipe ends.
After the heat soak phase, the hot plate is removed and the pipe ends brought together. The time taken to do this is called 'dwell time' and needs to be as short as possible. The final phase is the welding/cooling time, predetermined subject to pipe diameter and wall thickness.
