Characteristics of droplet transfer of electrode metal during MMA depending on the chemical composition of the material of the rod of the coated electrode

Abstract

This article presents the results of experimental studies of the effect of the coated electrode material for MMA welding on the droplet transfer parameters of electrode metal. It has been established that the use of coated electrodes based on copper (OZCH-4) and aluminum (Castolin EC 4001) alloys, compared to traditionally used metal rod based electrodes (Sabaros me20|10, LB-52U), affects the mass transfer characteristics of droplets electrode metal, in the form of an increase in the average duration of arc burning at intervals of melting of the electrode and the period of formation of drops of electrode metal up to 4 times.
