An integrated methodological platform is formed for diagnostics, restoration, and quality control, combining economic-engineering analysis of total cost of ownership (TCO), metallurgical approaches to controlling the heat-affected zone (HAZ), and techniques of on-site precision machining. Within the scope of the work, it is demonstrated that the described approach, based on a strict regulation of thermal cycling of welding operations using nickel alloys and on the use of mobile boring and build-up welding systems, makes it possible not only to radically reduce downtime and current expenses compared to replacement, but also to provide the restored component with wear resistance that exceeds the original specifications. At the same time, implementation limitations are documented: the need for capital-intensive equipment and increased qualification requirements for technical personnel. It is argued that the institutionalization of an engineering-centric culture of asset restoration is a strategic imperative for strengthening operational resilience and for an actively managed life cycle of equipment. The materials presented in this work will be of interest to service engineers, heads of technical departments, repair specialists, and technical directors of enterprises in the construction and mining industries.HAL open archive record: https://hal.science/hal-05855801 (hal-05855801)
