This monograph is a first-of-its-kind compilation on high deposition pulse current GMAW process. The nine chapters of this monograph may serve as a comprehensive knowledge tool to use advanced welding engineering in prospective applications. The contents of this book will prove useful to the shop floor welding engineer in handling this otherwise critical welding process with confidence. It will also serve to inspire researchers to think critically on more versatile applications of the unique nature of pulse current in GMAW process to develop cutting edge welding technology.

Pulsed-current is used primarily with the gas tungsten-arc and gas metal-arc welding processes and, to a limited degree, with plasma-arc welding. The pulsed-current arc welding processes employ two levels of welding current instead of the single level that is used conventionally. Welding current is, in effect, switched between a high and a low level to produce a 'pulsating' current or welding arc. Pulsed-current processes offer important advantages, including, among others, improved control of welding heat input rates, reduced distortion of the parts during welding, improved weld quality, and improved control of weld metal deposition in all welding positions. Pulsed-current gas tungsten-arc (PC-GTA) and pulsed-current gas metal-arc (PC-GMA) welding processes have been used for joining a variety of materials, including some that are often considered difficult-to-weld materials. The memorandum reviews the available literature that has been published on pulsed-current arc welding processes. In addition, information was obtained from numerous representatives of pulsed-current equipment manufacturers and users. (Author).

This book covers virtually all technical aspects related to the selection, processing, use, and analysis of superalloys. The text of this new second edition has been completely revised and expanded with many new figures and tables added. In developing this new edition, the focus has been on providing comprehensive and practical coverage of superalloys technology. Some highlights include the most complete and up-to-date presentation available on alloy melting. Coverage of alloy selection provides many tips and guidelines that the reader can use in identifying an appropriate alloy for a specific application. The relation of properties and microstructure is covered in more detail than in previous books.
