PRACTICAL ASPECTS OF PART RECONDITIONING BY WELDING

Abstract

The restoration of machine functionality through the reconditioning of worn parts is an effective method of reducing repair costs and time, eliminating the need to purchase replacement parts and, in some cases, extending the service life of components. The process includes stages such as cleaning, defect identification, determination of material properties, and the selection of suitable reconditioning methods and materials. Due to its versatility and low cost, welding is used in more than 80% of metal reconditioning cases. The article presents the stages, procedures, and technological parameters of part reconditioning by welding, the criteria for selecting the appropriate processes, and the analysis of possible defects, while also providing recommendations for their prevention.
