Advanced welding processes

J Norrish, University of Wollongong, Australia

 - an essential guide to selecting the best welding technology for mechanical and structural engineers
 - provides an excellent introductory review of welding technologies
 - topics include gas metal arc welding, laser welding and narrow gap welding methods

Advanced welding processes provides an excellent introductory review of the range of welding technologies available to the structural and mechanical engineer. The book begins by discussing general topics such power sources, filler materials and gases used in advanced welding. A central group of chapters then assesses the main welding techniques: gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), high energy density processes and narrow-gap welding techniques. Two final chapters review process control, automation and robotics.

Advanced welding processes is an invaluable guide to selecting the best welding technology for mechanical and structural engineers.
