ARC WELDING BY SINGLE COATED ELECTRODE Russian patent published in 2015 - IPC B23K9/95 

FIELD: process engineering.

SUBSTANCE: invention relates to welding by coated electrode. Claimed process allows a constant rate of electrode fusion in time. Arc current density J in time t is adjusted in compliance with the formula , where β is the proportionality factor equal to β=(A_f - A₀)/t_eJ₀, A₀ is the initial magnitude of electrode fusion factor, A_f is the final magnitude of electrode fusion factor, J₀ is the initial current density at the electrode at arcing, t_e is the time of electrode complete consumption at current density J₀ at the electrode.

EFFECT: higher efficiency of welding.
