The object of the study is the dependencies of the interaction of laser radiation with the material during the deposition of layers of powder material on a thin-walled base made of heat-resistant corrosion-resistant steel. The problem this study addresses is that during the manufacturing of thin-walled body parts, the design of which contains functional elements that differ significantly in their characteristics from the parts themselves and are intended to perform a different set of certain critical tasks. Typically, these elements are created using argon-arc cladding, microplasma cladding and other processes, but products obtained using such technologies have a significant proportion of defects due to the high chance of defects such as penetration and deflection under the influence of thermal deformations. This work proposes the use of laser radiation for cladding of functional elements and studies methods for minimizing the chances of defects such as deflection as well as burn-through of a thin-walled base. Experimental studies have been conducted, the results of which have been used to refine the methods for cladding of functional elements on a thin-walled base. The results of this work prove the prospects of using laser technology for cladding of functional elements onto a thin-walled base. As a result of the work, methods were developed to minimize the influence of laser radiation on the formation of a deflection defect by 60–80% and to completely prevent any burn-through. These methods are based on the principle of increasing the area and speed of thermal energy distribution, which allow for formation of defect-free cladded layers. The results of this work are planned to be used during development of technologies for laser cladding of functional elements onto thin-walled parts of critical structures of products in space, aviation, chemical, instrument-making and other industries. 17 Ref., 1 Tabl., 10 Fig.
