Analysis of the restoration process of surfaces of railway turnout elements by build-up welding

The practice has show that restoration of the surface of railway turnout elements by a build-up welding very often is unsuccessful due to subsequent origination of areas of premature destructions such as shivers, stratification, spalling, a.o. Experimental study revealed that causes of the defects are due to welding technology violations and ineffective turnout element existing defect diagnosis methods applied.
