Summary
The fusion welding is the main technological process applied in the production of weldments. It's known, that depending on the kind of the applied heat source, the following fusion welding processes are distinguished: electric arc, electron beam, laser beam, electroslag, light beam, and gas welding. However, irrespective of the applied welding procedure, the main goal of any process is producing a sound welded joint. This is only possible with a sufficiently comprehensive allowance for the physicochemical processes proceeding. Presenting the latest research on the topic, Physical Chemistry of Fusion Welding is a cutting edge and comprehensive book. The book contains modern representations by physicochemical processes, that occur on the borders of contacting phases: solid liquid metals, metal slag, metal gas, metal slag gas and the structure and properties of its phases: solid and melt metals, slags, and gases. In the book established the role of physicochemical processes in the formation of the weld and deposited metal; the formation of defects of the welding joints (solidification, liquation, polygonization, and cold cracks, non-metallic inclusions, pores, undercuts, lack of penetration, and etc.). The possible advancement of welding materials and technologies of welding and surfacing on the bases of prior research are also shown. Physical Chemistry of Fusion Welding presents this knowledge in a thorough and accessible manner, making it the ideal text for practical and scientific specialists in the fields of welding and metallurgy.
