Welding Metallurgy and Weldability describes weld failure mechanisms associated with either fabrication or service, and failure mechanisms related to microstructure of the weldment. Weldability issues are divided into fabrication and service related failures; early chapters address hot cracking, warm (solid-state) cracking, and cold cracking that occur during initial fabrication, or repair. Guidance on failure analysis is also provided, along with examples of SEM fractography that will aid in determining failure mechanisms. Welding Metallurgy and Weldability examines a number of weldability testing techniques that can be used to quantify susceptibility to various forms of weld cracking.

John C Lippold :- John C. Lippold received his BS, MS, and PhD degrees in Materials Engineering from Rensselaer Polytechnic Institute. Upon completion of his formal education, Dr. Lippold worked for seven years at Sandia National Laboratories, Livermore, CA, as a member of the technical staff, specializing in stainless steel and high alloy weldability. From 1985 to 1995, Dr. Lippold worked for Edison Welding Institute. From 1995 to the present, he has been on the faculty of the Welding Engineering program at The Ohio State University and was recently named a College of Engineering Distinguished Faculty member.
