Features: This book is written to match the basic knowledge requirements for electric welders and gas welders in the "Vocational Skill Qualification Assessment Specification and Examination Outline" jointly issued by the former Ministry of Labor and the Ministry of Machine Industry. The book is divided into nine chapters, mainly introducing the properties of metal materials, the crystallization of metals and alloys, basic knowledge of heat treatment for iron and steel, as well as the grades, compositions, properties, and applications of commonly used metal materials. The chapter arrangement is logical, integrating both beginner and intermediate content while allowing them to be separated independently, with clear markings. In terms of content, it is concise, practical, targeted, and adaptable. The book adopts the new national standards for technical terms, material grades, and legal metrological units. It is primarily intended for technical training of electric and gas welders (with content marked with being mandatory for intermediate-level workers), and can also be used by students in relevant programs at vocational secondary schools and technical schools.
