Searching for highly-efficient technologies of welding position butt joints of pipes is especially urgent, particularly during operation performance in site. The paper gives the results of comprehensive research on optimization of the technology of pressure welding of pipes with more than 4–5 mm wall thickness, using a controlling magnetic field. Methods of heating pipe edges by magnetically-impelled arc, algorithms of controlling the main parameters of pressure welding have been determined and comprehensive testing of the joints has been performed. Possibility of achieving high values of welded joint impact toughness in welding high-strength pipe steels is shown. 10 Ref., 7 Figures, 5 Tables.
Keywords: pressure welding, controlling magnetic field, magnetically-impelled arc, thick-walled pipes, welding technology, site and stationary conditions, mechanical properties
