This book presents an overview of the electric arc characteristics, particularly those that are important for welding applications. This more scientific approach intends to provide insights for a better understanding of the phenomena that control the behavior of an arc welding process. The text aims to emphasize physical phenomena that are important to arc welding, not dealing with technological, industrial or metallurgical aspects of welding. Among other topics, the following topics are included in this manuscript: heat sources for fusion welding, electric discharges in gases, arc evaluation techniques, electric arc profile, metal transfer, wire melting rate and process stability.

The Physics of Welding, Second Edition covers advances in welding physics. The book describes symbols, units and dimensions; the physical properties of fluids at elevated temperatures; and electricity and magnetism. The text also discusses fluid and magneto fluid dynamics; the electric arc; and the electric arc in welding. Metal transfer and mass flow in the weld pool, as well as high power density welding are also tackled. Students interested in welding physics will find the book useful.

Arc welding is one of the key processes in industrial manufacturing, with welders using two types of processes - gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). This new book provides a survey-oriented account of the modeling, sensing, and automatic control of the GMAW process.Researchers are presented with the most recent information in the areas of modeling, sensing and automatic control of the GMAW process, collecting a number of original research results on the topic from the authors and colleagues. Providing an overview of a variety of topics, this book looks at the classification of various welding processes; the modeling aspects of GMAW; physics of welding; metal transfer characteristics; weld pool geometry; process voltages and variables; power supplies; sensing (sensors for arc length, weld penetration control, weld pool geometry, using optical and intelligent sensors); control techniques of PI, PID, multivariable control, adaptive control, and intelligent control. Finally, the book illustrates a case study presented by the authors and their students at Idaho State University, in collaboration with researchers at the Idaho National Engineering and Environment Laboratory.

The Science and Practice of Welding, now in its tenth edition and published in two volumes, is an introduction to the theory and practice of welding processes and their applications. Volume I, Welding Science and Technology, explains the basics principles of physics, chemistry and metallurgy as applied to welding. The section electrical principles includes a simple description of the silicone diode and resistor, the production and use of square wave, and one-knob stepless control of welding current. There is a comprehensive section on non-destructive testing (NDR) and destructive testing of welds and crack tip opening displacement testing. The text has been brought completely up to date and now includes a new chapter devoted to the inverter power unit. Duplex stainless steel has been included in the list of material described.
