Welding Craft Practice, Volume 1: Oxy-acetylene Gas Welding and Related Studies, Second Edition covers the ground necessary for the acquisition of the essential basic skills and safe working methods and sufficient technology in oxy-acetylene gas welding and related studies. Weld defects, testing of welds, and welding science are discussed, and a graduated series of practical exercises is included. This volume is comprised of five chapters and begins with an overview of the basics of oxy-acetylene gas welding, including the gases used (acetylene and oxygen, welding systems and equipment, and safety precautions and fire prevention. The next chapter deals with the basic types of welds and the technique of oxy-acetylene gas welding, with emphasis on fusion welding of cast iron, bronzewelding and brazing, and building up worn parts. The reader is also introduced to the process of oxygen cutting of steel as well as inspection and testing of welds. The final chapter presents the results of related studies such as those concerning commonly welded metals and alloys; structure and mechanical properties of metals; and the state and structure of matter. This book will be of interest to welders, plumbers, metal workers, students, and those who wish to learn the basics of welding.
