LOW ALLOY STEEL SHAFT SURFACE REGENERATIVE WELDING WITH MICRO-JET COOLING

Abstract

In this paper, the effect of surface preparation after innovating welding technology with micro-jet cooling was reported. Substantial information about parameters of steel machine elements surfacing with the micro-jet cooling process was given. Recorded evidence concerning the influence of various microjet parameters on the metallographic structure of the machine shaft after surface welding was taken. There were tested metallographic and tribology properties of welds. The tribology interactions of a solid shaft surfaces were examined after surface welding.
