摘要：

The article discusses the technology of repair by welding the ring-welded joints of gas pipelines made of steel with high rates of deformability. The influence of technology on the structure and properties of welded joints has been studied. Choice of welding procedure for repairs of circular welded joints of gas pipelines is justified. © 2021 Informa UK Limited, trading as Taylor & Francis Group.
