Lavrova O. Improving of equipment and technology for submerged strip overlaying with forced transfer of electrode metal

Purpose: development of the scientific basis for reducing energy consumption and improving the quality of the working layer caused by submerged strip electrode surfacing with forced transfer of electrode metal.The object of study: the process of strip overlaying welding with controlled mechanical transfer of electrode metal. Subject of research: the process of electrode metal transferring in submerged strip electrode surfacing with forced mechanical vibrations. Methods: the mathematical design of experiments, definition of moving arc on the strip electrode butt end. Novelty: the proposed method for determining the current value of the additional inertial force, thus improving the efficiency of the process and the quality of welding. Functional dependence of the kinematical parameters of forced transfer and the deposition rate has been established, and the optimal parameters are: strip electrode bending angle is 120-140 °, the oscillation frequency is 40-60 Hz, and the eccentricity in the range 0.5-1.5 mm, thus improving the rate of melting of the electrode metal by 15-20%. Application areas: metallurgy and machinery.
