Motyakhov – Electric arc welding of metals
Motyakhov’s book, “Electric Arc Welding of Metals“, examines the theory of electric arc welding, the design of modern automatic and semiautomatic welding machines, and power sources. It also presents the fundamentals of technology and production of welded structures made of carbon and alloy steels, non-ferrous metals, and their alloys. It also briefly addresses the issues of welding mechanization and quality control.
The book, “Motyakhov – Electric Arc Welding of Metals,” is intended as a training tool for improving the skills of electric welders, as well as for independent study of electric arc welding.
To accelerate technological progress, improve labor productivity, and enhance the quality of manufactured products, it is necessary to widely implement the latest advances in science and technology in welding production. This objective is being successfully addressed by establishing large, specialized plants with a high degree of welding mechanization, restructuring welding operations, and increasing the adoption of advanced welding methods (automatic and semiautomatic submerged arc welding, gas-shielded welding, electroslag welding, etc.).
Motyakhov’s book, “Electric Arc Welding of Metals,” develops and commercializes new designs of welding arc power sources, equipment for mechanized welding methods, and assembly and welding fixtures.
Flow-rate and mechanized production of automobiles, ships, railcars, mining and chemical equipment, electrical equipment, road construction machinery, and pressing equipment using automatic and semiautomatic submerged-arc and gas-shielded welding has increased labor productivity by 5-10 times, improved the quality of welded joints, and significantly reduced metal and energy consumption. Various mechanized surfacing methods are widely used in the restoration of worn machine parts and mechanisms, as well as in the manufacture of new parts with wear-resistant surfaces. Universal and specialized automatic and semiautomatic welding machines, equipment, and devices for installing and handling parts, and supplying flux and gas to the welding zone are manufactured for this purpose.
The introduction of new welding methods, including gas-shielded welding, electroslag welding, and others, has resolved the widespread use of welded parts and assemblies (assemblies) made of special steels, non-ferrous metals, and their alloys in industry. Industry produces a wide variety of electrode grades for arc welding structures made of carbon and alloy steels, including heat-resistant, corrosion-resistant, heat-resistant, heat-resistant, and other steels. Electrodes are also manufactured for repair and wear-resistant surfacing of various steels, as well as for welding and surfacing cast iron and non-ferrous metals.
The development of welding production and the introduction of advanced welding methods in the national economy are increasing the training requirements for welders. Improving the theoretical knowledge and practical skills of welders, as well as mastering new welding methods and techniques, is one of the key tasks in mastering and implementing the latest advances in welding science and technology.
