      Foreword

      The book, “Arc Welding Processes Handbook”, brings together salient knowledge of arc welding methods used primarily in the industry and especially in the oil patch. The information presented about the welding process is usable and emulates the presence of your own welding engineer. Covering such welding methods as SMAW, GTAW, GMAW, FCAW and SAW with details in materials and techniques. This book is useful to both new welders as well as experienced welders. In the book, Ramesh covers these welding processes, how they work, and dives into the electrical side of welding. Welding machines, Transformers, Generators, Invertors, AC, DC, Sq. wave, Sine wave currents, Rectifiers, SCRs, Diodes, etc., as current control methods, all these are presented in a way that is easy to understand the functions of various welding machines. Most common weldable materials are discussed with welding guidance given that includes Aluminum, Nickel, Carbon steels, Stainless steels, Precipitation Hardened steels, Duplex Stainless steels, and others. The book is super comprehensive, easy to follow, and a welcome addition to any welding engineer’s bookcase. It is a truly great guide for any budding engineer or welder to help them master their skills.
