Abstract:
The impact of the initial structure on the wave
parameters and the quality of the waveguides bimetallic pipes
welding is examined in the current paper. It is demonstrated
that in order to obtain a reliable and durable welded joint, it is
preferable to use the annealed fine-grained initial pipes. The
test results demonstrate the formation of a stable and durable
joint of the bimetal layers. Among the quality metrics of the
bimetal with a relatively thin cladding layer is also the
uniformity of the cladding layer. It is more correct to consider
using the yield strength with a certain correction instead of the
hardness parameter while calculating the Reynolds number,
which allows to take into consideration the welded metals
structural changes and their impact on the type of the weld
boundary and the quality of the weld joint to the fullest extent.
A comparative assessment of the multilayer waveguide
manufacturing technologies for further economic analysis of
the technology profitability was conducted.
