Abstract: In the modern world, the use of nano- and ultrafine materials in welding processes is becoming more and more relevant. Of particular interest is the use of such materials in manual arc welding with single coated electrodes. This topic attracts the attention of researchers and engineers, since the use of the latest technologies can significantly improve the quality of welding and increase the efficiency of the process. Analysis of research results in the field of application of nano- and ultrafine materials in manual arc welding with single coated electrodes is the subject of this article. Within the framework of the work, the main methods of using these materials will be considered, as well as their impact on the characteristics of the welded joint. The presented review will help to better understand the prospects for the use of nano- and ul-traditionally dispersed materials in the field of manual arc welding, as well as to identify opportunities for optimizing the process for the best results. This article discusses the introduction to the use of nano- and ultrafine materials in production, especially in manual arc welding with single coated electrodes. Nano- and ultra-dispersed materials are an area of innovative technologies that improve the quality and efficiency of the welding process. Their application in the welding industry has great potential for improving the strength, corrosion resistance and other characteristics of welded joints. Studies show that the use of nano- and ultrafine materials in manual arc welding can significantly improve the quality of welded joints, increase productivity and reduce the number of defects. However, for successful implementation of these materials, it is necessary to take into account the peculiarities of their interaction with coated electrodes, as well as to develop special technologies and methods for welding.
