Abstract

At this article presented the results of studies on the influence of wollastonite concentrate obtained from wollastonite ore of the Koytash deposit of the Republic of Uzbekistan on the properties of coatings of welding electrodes. The obtained results revealed the dependence of the pressing pressure of the electrodes on the content of wollastonite concentrate in the electrode coating, according to which the introduction of wollastonite concentrate in the coating of the base type is conducive to improving the plastic properties of the coating masses. Also, studies of the effect of wollastonite concentrate on the arc stability of the welding electrode, which showed an increase in the breaking length of the arc and increase the stability of its combustion when introduced into the electrode coatings of wollastonite concentrate. In addition, the favorable effect of wollastonite concentrate on the grinding of electrode metal droplets and the improvement of the formation of welds was revealed.
