Analysis and results of the conducted research work to increase the resource of the ginning rib

This article describes the technology for restoring worn working surfaces of a grate of a saw gin by surfacing them. Inlet wear of the working surfaces of the grate of the gin causes poor fiber quality. Worn parts lead machines to work with a deviation from the set parameters, reduces the efficiency of machines, leads to the emergence of additional load-bearing machines, which leads to a deterioration in the operating condition and the weakening of machinery mechanisms. To avoid these disadvantages, it is more economical to weld and cover the used electrodes, instead of replacing worn-out gin grates with new ones. On the basis of the executed researches recommendations about introduction of alloying elements in building-up welding metal are given
