Abstract
Application of dry underwater welding in repair of underwater passages of main gas and oil pipelines across rivers is considered. A new specialized mobile diving complex, designed for repair main gas pipelines of 1020 and 1220 mm diameter at the depth from 2 up to 30 m using the dry underwater welding, passed the full-scale tests, is described in detail.
