Description
WILEY INDIA Welding Metallurgy 2Nd Edition by Sindo Kou
Welding Metallurgy by Sindo Kou has been used worldwide as a reference book for welding practitioners and researchers since it was published in 1987. It has also been used for teachingc welding in universities in more than ten different countries. Significant progress has been made in the field of welding metallurgy in the past 13 years and a second edition of the book is therefore badly needed.
About the Author
Sindo Kou is Professor and Chair of the Department of Materials Science and Engineering at the University of Wisconsin.
