The temperature field dynamics and estimation of technological parameters at welding by friction with hashing of bimetallic plates

In article the mathematical model of dynamics of temperature distribution at welding by friction of bimetallic connections is developed. The offered mathematical model allows to determine the process of two diverse metal sheets heating in the course of welding by friction with hashing. In its losses on radiation and heat emission in medium are considered. The model has been checked experimentally at connection with an overlap of plates from aluminum alloy AD31 and copper alloy M3.
