The paper presents the results of studies of a material structure formed in the process of the developed technology for welding a saddle branch to a polyethylene pipe at low air temperatures. The temperature-time mode of welding saddles to a polyethylene pipe at low temperatures, implemented by the proposed technology, makes it possible to obtain a material structure that ensures the strength of the joint at the strength level of standard welding at permitted air temperatures.
