Title: Innovations of Sergei M Samotryasov
Introduction
Sergei M Samotryasov is a notable inventor based in Kyiv, Ukraine. He has made significant contributions to the field of welding technology, holding a total of 3 patents. His work focuses on improving welding processes, particularly flash-butt resistance welding.
Latest Patents
One of his latest patents is a method for controlling a flash-butt resistance welding process. This innovative process includes steps for upsetting the flashing parts being welded. The flashing is conducted with concurrent measurement of useful electric power and an electric parameter of the flashing process, which is related to the power by a function that maximizes the useful power at a predetermined value of the electric parameter. The process involves determining the value and sign of the power and parameter increments within the same period of time. The parts are brought closer together until the ratio of the power and parameter increments reverses its sign. Subsequently, the parts begin to be separated until the value of the ratio reaches a preset value suitable for the welding circuit resistance and the cross-sectional area of the welded parts. Another significant patent is the flash-butt resistance welding process itself, which includes flashing the parts being welded and their upsetting. The direction of speed of motion of the parts during flashing is altered by converging and diverging them. The parts are converged until the total resistance of elementary contacts between the flashed surfaces equals 0.4-0.5 of the short-circuit impedance of the welding machine. They are then diverged until the summary resistance of elementary contacts reaches 1.4-1.6 of the short-circuit impedance.
