O. Paton Elektric Welding Institute National Academy of scinces of Ukraine popup.description1 The purpose of the work is to develop high-performance technologies based on research welding in different spatial positions of metal of large thicknesses (mostly in one pass) with forced formation of seams popup.description2   The essence of the work is to conduct comprehensive research on welding processes with forced formation of the weld metal to determine the patterns of high-quality formation, defect-free weld metal and ensuring the necessary mechanical properties. The purpose of the project is to develop, on the basis of the research conducted, highly effective welding technologies in various spatial positions of large-thick metal (mainly in one pass) with forced formation of the deposited metal. As part of the research conducted, the influence of the specific linear energy of the process on the quality of the formation of the weld, the properties of the weld metal and the HAZ was studied, the influence of the thermal cycle on the deformation of the work pieces was investigated. Also carried out: selection of welding materials, studies of macro and microstructure, mechanical tests of welded joints. As a result of the work, special technological equipment of a modular type was developed and manufactured, which can be used both in shop and installation conditions when welding in various spatial positions. As a result, typical technological instructions (рWPS) were developed for electroslag and electric arc welding of butt joints of steel 09Mn2 steel with a thickness of 45 mm.
