This antique book contains information on electric, forge, and thermit welding, together with related methods and materials used in metal working - and the oxygen process for removal of carbon. The object of this book was to cover the several processes of welding, along with other processes that are closely allied in method and subject of joining metal to metal with the aid of heat. Much practical information is given on the uses and characteristics of the various metals; on the production, handling and use of various gasses and other materials which are part of the equipment; on the tools and accessories for the production; and the handling of these materials. The chapters of this book include: 'Metals and Alloys', 'Welding Materials', 'Acetylene Generators', 'Oxy-Acetylene Welding Practice', 'Electric Welding', etcetera. This book was originally published in 1916, and we are proud to republish it now complete with a new introduction on the subject.
