Corrosion failures of industrial components are commonly associated with welding. The reasons are many and varied. For example, welding may reduce the resistance to corrosion and environmentally assisted cracking by altering composition and microstructure, modifying mechanical properties, introducing residual stress, and creating physical defects. Corrosion of Weldments details the many forms of weld corrosion and the methods used to minimize weld corrosion. Chapters on specific alloys groups—carbon and alloy steels, stainless steels, high-nickel alloys, and nonferrous alloys—describe both general welding characteristics and the metallurgical factors that influence corrosion behavior. Corrosion problems associated with dissimilar metal weldments are also examined. Special challenges caused by high-temperature environments are discussed.

This book presents a practical "how to" approach to understanding and solving the problems of corrosion of structural materials. Although it is written mainly for those having a limited technical background in corrosion, it also provides more experienced engineers with a useful overview of the principles of corrosion and can be used as a general guide for developing a corrosion-control program. This electronic publication includes identification of the various forms of corrosion, critical factors leading to a specific type of corrosion, necessary preventive steps to eliminate or reduce corrosion damage, protective-coating selection, corrosion characteristics of common structural materials, corrosion-testing programs, and failure-analysis procedures.
