Metal Casting & Joining

Designed for the undergraduate students of mechanical engineering and allied branches, this book serves as a bridge between the study of the basic processes and their application in production industries.

This book covers two similar fundamental processesfoundry and weldingin a single volume. The chapters of the book are grouped in seven modules. A separate module is devoted to introduce the preliminaries of the two areas namely casting and joining processes. Miscellaneous welding and allied processes, including the modern methods and thermal cutting, conventional sand mould casting, special and modern casting methods, conventional metal joining processes and theory of solidification of metal, its metallurgy, defects in castings and casting design procedure are covered in the book. The theory of each process is explained with the help of simple line sketches which can be easily reproduced by a student at the time of examination. Enough worked out examples and problems are given for practice, especially in the design areas. At the end of each chapter, sufficient number of review questions are given as exercise.
