M. : MGSU, 2010. - 88 s. The textbook is designed to help students of full-time and correspondence departments of the faculty of TPP, as well as externality in studying the section "Welding", provided by the discipline "Metal structures, including welding" . The manual provides basic information about the types of welding, welding materials, welds and welded joints used in construction. Technical and economic criteria for the assessment of types of welding, welding materials and welding equipment in the manufacture and installation of metal structures . The main purpose of the textbook is to form a generalized system of knowledge about the features of one of the most common technological processes in the manufacture of building metal structures - welding. Including familiarizing students with the following sections of welding science and technology: the essence of welding as a process of formation of interatomic bonding of metals ; basics of technological processes of welding of metal building structures, mechanization, automation and robotization of welding works in construction. welding materials and equipment, types of welds and welded jointsmain methods of quality control of welded joints, ensuring the operational reliability and durability of building structures ; calculation of welded joints and assemblies of metal building structures ; formation and development of welding stresses and deformations in building metal structures and their impact on the performance and accuracy of structures, as well as measures to reduce them ; Weldability of construction steels and causes of cold and hot cracks in welded joints. Manufacturing process of welded metal constructions. The main tasks of studying the section:the formation and development of engineering thinking in the field of welding as the main technological process in the manufacture and installation of building metal structures ; mastering the principles of proper selection of the type and mode of welding , Welding Materials , Welding Equipment , Emergency welding equipment , mastering the principles of proper choice of methods of quality control of welded joints , ensuring the operational reliability and durability of metal constructions ; knowledge of the basics of the theory of the formation of welding stresses and deformations and mastering the principles of the correct choice of measures to reduce them ; knowledge of the bases of calculation of welded joints of metal structures ; mastering the design principles of assembly-welding technology of building structures .
