Features: This book is written to meet the basic knowledge requirements for electric welders and gas welders as specified in the "Occupational Skill Qualification Standard and Assessment Outline" jointly issued by the former Ministry of Labor and the Ministry of Machine Industry. The book is divided into nine chapters, primarily introducing the properties of metal materials, the crystallization of metals and alloys, basic knowledge of heat treatment for iron and steel, and the grades, compositions, properties, and applications of commonly used metal materials. The chapter arrangement is logical, integrating both beginner and intermediate content while allowing for independent separation, 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 an asterisk being mandatory for intermediate-level workers), and can also be used by students in relevant programs at vocational secondary schools and technical schools.
