В работе рассмотрены вопросы разработки и применения новой методики сварки больших стальных плит мостовых переходов. Приведена технологическая процедура такой методики в применении к штатным мостам. Установлено, что использование стеклянной подложки существенно не влияет на физико-механические свойства как самих сварных швов, так и металла вблизи них. Доказана надежность и целесообразность применения такой методики на реально возведенном мостовом переходе через р. Чулым. Делается вывод о научной составляющей методики, которая заключается в том, что экспериментально доказывается процесс уравновешивания остаточных напряжений в зоне термического влияния в ходе выполнения сварочных работ.

The paper deals with the development and application of a new technique of welding large steel plates of bridges. The technological procedure of this technique as applied to regular bridges. It is found that the use of a glass substrate does not significantly affect mechanical properties of both welds and metal near them. The reliability and usefulness of this technique is proved on the real bridge erected over the river Chulym. The process of balancing the residual stresses in the thermal effect zone is experimentally proved during welding work.
