Abstract High performance properties are important for enterprises focused on the use of technologies with low resource intensity and automation in the fabrication of metal products, permanent joints, and this segment is especially important for shipbuilding enterprises. To solve this problem, a series of experimental studies has been carried out to determine an effective mode of combined thermal exposure towards formation of structure and physical and mechanical properties of metal in the heat-affected zone of the weld fabricated by the method of automatic submerged arc welding using flux-cored wire with aluminothermic filler. The peculiarity of utilization of this wire is that the electric arc and aluminothermic process can be combined. As a result of the experimental study permanent joints made of steel St3sp have been obtained; its values of impact strength, tensile strength and yield strength are also presented. The optimal values of the thermal exposure mode during alumothermic welding have been determined, which lead to obtain the most preferable strength properties of the permanent joint. © 2022 The Authors.
