Book excerpt: This book, titled Non-destructive Testing Techniques meets the requirement for a text book on Non-Destructive Testing and also a support text for courses on Materials Science and Technology/Materials Testing and Technology. These courses are offered in Institutions/University across the country and the book is quite useful for students of these courses. To help students to master their subject knowledge; Multiple Choice Questions (MCQs) with Answers have been provided at the end of the book. All the Chapters have been written in a simple language for better understanding of non-destructive te4sting techniques. The knowledge and practice of Non-Destructive Testing Techniques leads to having an additional technical skill and industries employ persons having this skill set. Besides serving the primary purpose of providing a textbook on the subject on Non-destructive Testing Techniques, it would also provide a much-needed reference to various engineers and research-scientists that use Non-destructive Testing Techniques for inspection purposes or for material behavior research studies. Persons working in the area of non-destructive testing in large fabrication industries, chemical and nuclear industries, aerospace industries, transportation including railways, etc. would also find the book very useful.
