Features: The content of this book is divided into three main parts: Part I is the fundamental theoretical knowledge, including the basics of metallurgy and heat treatment (Sections 1-7 are suitable for primary electric and gas welding; Sections 8-13 are suitable for intermediate electric and gas welding), basic electrical knowledge (suitable for primary electric and gas welding), and the fundamentals of welding and electrical work (suitable for intermediate electric and gas welding). The second part is the solved questions for the knowledge assessment of welding and electrical work, divided into primary and intermediate sections, which answer questions in the form of Q&A regarding welding joints, welding arcs, arc welding power sources, common arc welding methods, welding materials, welding fixtures and tools, welding safety and protection, welding metallurgical processes, gas-shielded arc welding, electroslag welding, welding of common metal materials, welding stress and deformation, and resistance welding processes and equipment. The third part is the solved questions for the knowledge assessment of gas welding, also divided into primary and intermediate sections, which answer questions in the form of Q&A regarding the use of gas welding and cutting equipment and tools, welding materials for gas welding, welding flames, gas welding and cutting processes and operations, welding defects and inspection, brazing, gas welding metallurgical processes, welding of common metal materials, welding stress and deformation. This book is a guide for the knowledge assessment and review of primary and intermediate electric and gas welders, and can also be used for self-study by welders as well as for reference when setting questions by assessment departments at all levels.
