Features: "Practical Technology for Maintenance of Large-scale Power Generation Units" is a technical series primarily focused on the process of major unit overhauls, with an emphasis on equipment maintenance for 300MW and above thermal power generation units. The series introduces the practical experience in maintaining 300MW and above units, defect handling of equipment, maintenance procedures, processes, and relevant quality standards for maintenance. It is rich in content and highly practical. This series serves as a guide for standardizing maintenance practices, ensuring quality, preventing rework, and addressing difficult maintenance issues encountered during the process. It greatly assists in popularizing knowledge and skills for large unit maintenance, improving the technical proficiency of maintenance technicians and management personnel. The complete series is divided into four sub-series: Steam Turbine, Boiler, Electrical, and Metal and Welding. This sub-series is the Metal and Welding volume, divided into two parts. The first part mainly includes fundamental knowledge of metallic materials, metal technology supervision in thermal power plants, periodic inspection and management of in-service pressure vessels, metal inspection methods in power plants, fracture and metallographic analysis of metal accidents in power plants, and field inspection and repair case studies. The second part mainly covers an overview of the development of welding technology for maintenance in thermal power plants, basic knowledge of welding for maintenance in thermal power plants, basic process requirements for welding in thermal power plant maintenance, common pipeline welding techniques for maintenance in thermal power plants, welding techniques for heat transfer surface tubes of boilers for maintenance in thermal power plants, welding repair of defects in steam turbine equipment for maintenance in thermal power plants, welding case studies of boiler equipment, prevention and handling of welding defects, basic knowledge of heat treatment for welding in thermal power plant maintenance, and safety techniques for welding in thermal power plant maintenance. This series is suitable for maintenance technicians and management personnel from various disciplines engaged in thermal power unit maintenance, as well as technical personnel from maintenance and supervision companies. It can also serve as a technical training textbook for thermal power unit maintenance and as a reference for university teachers and students.
