Causes of Defects in Laser Cladding and Control Methods

Abstract

This paper presents a detailed analysis of the causes of crack defects, porosity defects, oxidation burn defects, substrate deformation defects in the process of operation, surface flatness not up to the expected defects and effective solutions to control the method, hoping to provide relevant practitioners with certain references to reduce the incidence of defects of the surface layer of the laser melting and cladding process from the fundamental level to improve the performance of the material, and ultimately to contribute to the development of China's manufacturing industry, and the development of a better, more efficient, and more effective way to reduce defects. In the end, it will make a better and greater contribution to the development of China's manufacturing industry.
