На трубах диаметром 36" с толщиной стенки 16 мм успешно продемонстрирована сварка кольцевого стыка в два полуорбитальных прохода на спуск со средней скоростью процесса 2 м/мин и мощностью лазера 19 кВт. Потолочное положение сварки (участок от 150° до 180°) является наиболее сложным с точки зрения обеспечения качественного формирования корня. Адаптация скорости подачи сварочной проволоки, скорости сварки, а так же применение формирующего газа заметно улучшают качество корня в потолочном положении сварки. Сканирующая оптика зарекомендовала себя как эффективный инструмент позволяющий расширить допуски на зазоры в стыке, а так же компенсировать небольшие ошибки позиционирования сварочной головки относительно стыка. Установленная для сваривемой толщины 16 мм величина зазора, при котором еще возможен стабильный процесс без дефектов сплавления, составляет 0,7 мм. При сварке обычной оптикой без сканирующего модуля величина максимально допустимого зазора кромок составляет 0,3 мм. С применением предварительного подогрева достигнуто увеличение времени охлаждения t8/5 с одной секунды до 16 секунд, что способствовало значительному снижению микротвердости в зоне термического влияния. Настоящие исследования проведены в рамках проекта MNPQ FK19/07 при финансовой поддержке Федерального Министерства образования и исследований Германии. Авторы выражают благодарность партнерам со стороны производства, фирмам Vietz GmbH и HIGHYAG, за плодотворное сотрудничество и предоставление оборудования для проведения экспериментов.</p></abstract><trans-abstract xml:lang="en"><p>Recently developed fibre lasers provide multi-kilowatt beam power with high quality at impressive energy efficiency. Combined with gas metal arc welding (GMAW) equipment these lasers can be used in a hybrid process to weld thick-walled constructions single-pass, that are currently welded using multi-pass techniques. The main benefits are a reduction of heat induced distortions, due to the low heat input, as well as savings in filler material and process time. Probable applications can be found in power generation, ship building and pipeline constructions. An orbital (girth) laser-hybrid process using a 20 kW fibre laser and a GMAW torch is currently examined at the BAM, Berlin. The aim of this research is to obtain a stable and crack free girth welding process and to demonstrate its application in pipeline construction. The experiments are carried out on 16 mm thick plates as well pipe rings with 36" (914 mm) pipe diameter of X65. Particular welding parameters, such as welding speed, GMAW power, arc length are varied and their influence on the appearance of the weld in the different welding positions is analyzed. Even though issues remain that demand further research it could already be shown that the rings can be welded using a girth hybrid process that is divided into two half girth processes in downward direction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сварка</kwd><kwd>гибридная лазерно-дуговая сварка</kwd><kwd>орбитальная сварка</kwd><kwd>трубопроводы высокого давления</kwd><kwd>оптоволоконные лазеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-power fibre laser</kwd><kwd>pipeline</kwd><kwd>laser-hybrid welding</kwd><kwd>thick plates</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">Nakamura S., Ikuno Y., Maeda T., Furukawa Y., Kodama S.: Automatic control technology of welding machine MAG-II for onshore pipelines.
