Работа посвящена автоматизации технологического процесса сварки судокорпусных конструкций. В настоящее время большинство технологических процессов в судостроении сопряжено с использованием ручного труда и имеют низкую степень автоматизации. Авторами был проведен структурный и функциональный анализ типового технологического процесса сварки узлов корпуса судна, на основе которых был сделан вывод о необходимости повышения эффективности функционирования технологического процесса. Для этих целей был разработан роботизированный технологический комплекс электродуговой сварки узлов корпуса судна с применением интеллектуальных алгоритмов управления. Чтобы подтвердить эффективность предлагаемого решения, приведены результаты практической работы авторов по проектированию технологического процесса сварки судокорпусных конструкций в лабораторных условиях. The work is devoted to the automation of the technological process of welding ship hull structures. Currently, most of the technological processes in shipbuilding involve manual labor and have a low degree of automation. The authors carried out a structural and functional analysis of a typical technological process of welding ship hull units, on the basis of which it was concluded that it is necessary to increase the efficiency of the technological process. For these purposes, a robotic technological complex for electric arc welding of ship hull assemblies was developed using intelligent control algorithms. To confirm the effectiveness of the proposed solution, the results of the author's practical work on the design of the technological process of welding ship hull structures in laboratory conditions are presented.

Joining Process

The most used joining process in industry today is the electric arc welding, EAW. After recalling the principle of the process, the authors present that development of EAW in the last half century is mainly due to the mechanization and automation. Earlier only rigid-type automation forms were used, for highly repetitive mass production – but later the industry requests demanded to find flexible forms of automation, capable of providing a diversified production based on welding and its related processes. Ways are then exemplified concerning mechanization of processes currently used in the industrial field: driving devices for the welding head having one or more axes, simple and complex rotation movements etc. The authors present both important developments of the essential components of EAW robotic systems, as well for robots and for welding equipment, developments that brought these systems to the current levels. The paper also proposes a new concept of programming robotic arc welding systems, consisting in maintaining the two arc ends on both TCP’s, one of the robot and the other of the workpiece. Then modern control methods developed for the welding process are described: programming the evolution of arc parameters in relation to the time; controlling of variation limits and directing the transfer of metal and energy through the arc. Finally, some examples and applications of robotized arc welding and related processes are presented.

Fabrication and repair of aluminum components and structures commonly involves the use of electric arc welding. The interaction of the arc and the metal being welded generates ultraviolet radiation, metallic oxides, fumes, and gases. Aluminum is seldom used as the pure metal but is often alloyed with other metals to improve strength and other physical properties. Therefore, the exact composition of any emissions will depend on the welding process and the particular aluminum alloy being welded. To quantify such emissions, The Aluminum Association sponsored several studies to characterize arc welding emissions by the gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) processes for various combinations of base and filler alloys. In all cases, the tests were conducted under conditions that could be found in a production weld shop without forced ventilation. The concentrations of each analyte that a welder could be exposed to were greatly affected by the welding process, the composition of the base and filler alloys, the position of the welder, and the welding helmet. The results obtained can be used by employers to identify and control potential hazards associated with the welding of aluminum alloys and can provide the basis for hazard communication to employees involved in the welding of these alloys.
