materials, which ensure the quality of the connection in the conditions of machine-
building enterprises.
In this paper, the authors solved the actual scientific and practical problem of
improving the efficiency of manufacturing BTE in machine-building production by
developing a control method at the stage of development of the technological process,
which would allow to determine the parameters of the technological process of pulling
with refinement, which ensure the quality (strength) of the connection and allows to
predict the performance properties.
The basis of the work is the scientific idea of constructing the process of
manufacturing bimetallic tubular elements from individual layers of sheet blanks by
pulling with thinning in the heated state, which provides conditions for obtaining a
given shape of the product and connecting the layers.
Research results. On the basis of generalization of scientific publications the
standard scheme of manufacturing process of BTE which is focused on realization in
the conditions of small-scale production of the machine-building enterprises is offered
and presented in tab.1.
