Analysis of the welding-soldering process in heat exchanger tube boards by the explosive method

摘要

We study the process of kinematical welding-soldering of thin-walled tube boards and tube elements employed in the design of heat exchangers. This process is simulated by highspeed contact interaction of coaxial cylinders separated by a thin interlayer of high-strength amorphous solder, whereas the internal cylinder expands under the action of explosive pulse loading. In solving the problem of thermoelastoplasticity, we take into account the material dynamic properties. The process is experimentally studied on test specimens.
