Enterprises focused on obtaining one-peace metal structures that characterize by long-term operational strength, have significant competitive advantages, provided technologies that reduce resource consumption are used. Among these technological solutions is the process of obtaining a weld seam, which is formed due to the heat released as a result of joint electric arc and aluminothermic influences. Local heating is provided by feed to the joint area the surfaces of an extended rod-electrode (SE) made in the form of a steel shell with a thermite powder filler that consist of a mixture of iron oxide, a reducing agent and alloying components. The materials of such a mixture are mainly waste from the enterprises of the machine-building and metallurgical complex, which makes it possible to ensure their return to production. The main purpose of the work is the experimental determination the parameters of the thermal mode, at which the required strength characteristics of an one-peace joint are achieved. In this work are presented results of the experiment in which the influence of the energy effect on the stress-strain state and the strength characteristics of the obtained one-piece joint is determined.
