Abstract
The structure and phase features of the welds of the steel Сt3 +steel 12X18H10T", steel Сt3+
aluminum A5M, steel tт3+ copperM1 bimetallic compositions are considered. An undulating nature
of the material flow in the welding zone for all the above compositions is experimentally confirmed.
It is revealed that when the composition of low-carbon and stainless steel is used in explosion
welding, the flow pattern is laminar with a negligible wave asymmetry. A turbulent wave flow is
observed in the weld zone of low-carbon steel and aluminum. The wave flow in the metal
compound for the low-carbon steel and copper composition corresponds to a vortex type. Plastic
flow wave parameters such as wavelength and amplitude are experimentally determined.
