Paton Electric Welding Institute of the National Academy of Sciences of Ukraine popup.description2 The design of multi-layer build-up samples and research methods of fatigue life under cyclic thermal and mechanical loads. According to the developed technique to study the effect of the sublayer, weld wire Sv-08A, on the fatigue life of samples of steel 40X, clad cored wires PP-Np-25H5FM or PP-Hp-35V9H3SF. According to the results of calculations and experiments developed equipment and technology surfacing parts that operate under the joint action of cyclic thermal and mechanical loads. The developed technology provides increased 1.2...1.3 times the fatigue life of weld parts under cyclic thermal and mechanical loading. Using the results of investigations of fatigue life of deposited multilayer samples calculated the amount of allowable repairs of parts with welding. Pilot plant test results of studies on the subject conducted at "SP INDUSTRY-SERVICE" in a multi-layer surfacing feed rolls of hot metal and the company "Steel Vork" with multilayer cladding sheet structures.
