The paper proposes a technology for welding a saddle branch to polyethylene pipes, which allows to extend the range of permissible ambient temperatures for welding to minus 45 ° C. Shown are the results of separation tests of welded joints obtained at low temperatures. The use of the developed welding technology ensures the formation of a material structure in a welded joint, similar to the structure of the material of a welded joint obtained under conditions of permissible temperatures.
