Welding is a technique by which different materials are fused together. It may be a part of the fabrication process or used in artistic activities. Welding primarily uses electric current to melt metals and alloys, but gases, lasers and ultrasound may also be used. Development of new technologies, such as the arc welding machine, etc. have allowed welding processes to take place outside industrial settings. The topics covered in this book offer the readers new insights in the field of welding. This book, with its detailed analyses and data, will prove immensely beneficial to professionals and students involved in this area at various levels. | Welding by Gersham Levitt, Hardcover | Indigo Chapters
