**Preface to "Welding, Joining and Coating of Metallic Materials"**

This book is a collection of several reviews and original research papers that cover recent developments in the field of welding, joining and coating of metallic materials. These processes are highly applicable to industry, due to the materials having desirable properties and performance. Therefore, welding, joining and coating are also being studied in detail by scientists worldwide.

The following materials are the focus of this book: titanium, aluminum and magnesium alloys, as well as various types of steel, intermetallics and shape memory alloys. Particular emphasis is placed on the microstructural investigations during the welding, brazing and coating processes. However, in order to solve complex issues, works on modeling and simulation are also presented in the book.

Different metallurgy-related processes are covered, such as spot welding using metallic interlayers, the welding of dissimilar metals, the study of joints applicable as biomaterials. The advances in coating technologies covered in the book are related to the micro arc oxidation (MAO) method, the plasma vapor deposition (PVD) approach and the chemical vapor deposition (CVD) technique.

We would like to take this opportunity to thank all of the authors who have contributed to this book.
