Abstract

The thermal process of welding polyethylene pipes for gas pipelines at temperatures below standard is theoretically studied. The used mathematical model considers the heat of the phase change within the temperature range and the heat effect formed at burr setting. Computing experiments indicate the possibility of regulation by temperature conditions when welding at low ambient air temperature and the possibility of providing the same change of the temperature field as at admissible air temperature in the heat-affected zone.
