Исследование посвящено изучению влияния угла наклона приемной поверхности на участках с выпуклым и вогнутым профилем на изменение величины смещения единичного наплавляемого слоя при аддитивном формообразовании электрической дугой в среде защитного газа. Проведены экспериментальные исследования по формообразованию на приёмные поверхности с различным углом наклона. На основании полученных электродуговой наплавкой в среде защитного газа образцов, определены величины смещения единичных наплавляемых слоёв. Для оценки влияния угла наклона приёмной поверхности на смещение единичного наплавляемого слоя при аддитивном формообразовании электрической дугой в защитной среде, выполнен однофакторный дисперсионный анализ.</p></sec><sec><title>Методы</title><p>Методы: организации и планирования эксперимента, математической обработки результатов эксперимента, однофакторного дисперсионного анализа.</p></sec><sec><title>Результаты</title><p>Результаты. В результате проведения дисперсионного анализа выявлено, что угол наклона приёмной поверхности при аддитивном формообразовании изделий оказывает влияние на смещение единичного наплавляемого слоя на участках с выпуклым и вогнутым профилем, является значимым параметром при аддитивном формообразовании электрической дугой в среде защитного газа. В частности установлено, что критерий значимости для угла наклона составляет p &lt; 0,01. В свою очередь, для выпуклой поверхности составляет p &lt; 0,03, для вогнутой поверхности составляет p &lt; 0,004. Анализ результатов исследования показал, что угол наклона приёмной поверхности оказывает большее значение на величину смещения единичного наплавляемого слоя на участках приемной поверхности с вогнутым профилем. Заключение. Определено, что угол наклона приемной поверхности значительно влияет на изменение величины смещения единичного наплавляемого слоя при аддитивном формообразовании электрической дугой в сфере защитного газа. Угол наклона приемной поверхности на участках приемной поверхности с выпуклым и вогнутым профилем является значимым и его следует учитывать при проектировании технологических процессов аддитивного формообразования изделий электрической дугой в защитной среде.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of research</title><p>Purpose of research. The study is devoted to the study of the influence of the angle of inclination of the receiving surface with a convex and concave profile on the change in the displacement of a single deposited layer during additive shaping by an electric arc in a protective gas medium. Experimental studies on shaping on receiving surfaces with different angles of inclination have been carried out. Based on the samples obtained by electric arc welding in a protective gas medium, the displacement values of the individual deposited layers are determined. Since the angle of inclination of the receiving surface can affect the displacement of a single deposited layer during additive shaping by an electric arc in a protective environment, a one-factor dispersion analysis was performed. </p></sec><sec><title>Methods</title><p>Methods. Methods of organization and planning of the experiment, mathematical processing of experimental results, single-factor analysis of variance. </p></sec><sec><title>Results</title><p>Results. As a result of the dispersion analysis, it was revealed that the angle of inclination of the receiving surface during additive shaping of products affects the displacement of a single deposited layer and is a significant parameter during additive shaping by an electric arc in a protective gas environment. In particular, it was found that the significance criterion for the slope angle is p &lt; 0.01. In turn, for a convex surface it is p &lt; 0.03, for a concave surface it is p &lt; 0.004. Comparing the results, it can be seen that the criterion is more significant for a concave surface. </p></sec><sec><title>Conclusion</title><p>Conclusion. It is determined that the angle of inclination of the receiving surface significantly affects the change in the displacement of a single deposited layer during additive shaping by an electric arc in the sphere of protective gas. Therefore, the angle of inclination of the receiving surface with a convex and concave profile is significant and should be taken into account when designing technological processes for additive shaping of products by an electric arc in a protective environment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аддитивные технологии</kwd><kwd>формообразование</kwd><kwd>выпуклая поверхность</kwd><kwd>вогнутая поверхность</kwd><kwd>погрешность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>additive technologies</kwd><kwd>shaping</kwd><kwd>convex surface</kwd><kwd>concave surface</kwd><kwd>error</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Burns M.
