摘要：
The thermal process of welding a saddle branch to a polyethylene pipe is considered with the heat of the phase transition taken into account. The corresponding three-dimensional nonlinear equation of thermal conductivity is solved by the finite element method in a complex domain. The technological operations necessary for welding the saddle branch to the polyethylene pipe at air temperatures below standard are defined based on the study of the dynamics of the temperature field during welding at various ambient temperatures.
