Abstract

Abstract: The requirements for welding processes are particularly important in terms of building an open, where to get reliable connections  is  difficult,  expensive  or  impossible  to  use  machinery  and  stationary  devices.  In  such  cases,  the  implementation  of welding using mechanical vibrations in the construction of important structures is becoming a necessity. Therefore the aim of this work is to study the effect of vibration exposure low specific manner, the structure of power in the heat-affected zone and weld. Methods. Mechanical vibration of 250 watts at 60 Нz transmitted to the weld connection, wherein the elastic vibrations are excited. Investigation of elastic vibrations on the structure welded joints were made in mechanized welding the steel wire 10G2FB Megafil 821  R, 1.2  mm  diameter  in  a  mixture  of  argon and  carbon  dioxide. Practical  significance.  Thin  vibratory  oscillations  in  the frequency range 60 Hz contribute structure refinement and promote the formation of the weld metal more homogeneous structure.
