Application of heat sinks for reduction of welding strains and stresses (Review)

East-Ukrainian University, Lugansk, Ukraine

Abstract
The possibilities of controlling the strains and stresses in the joints with artificial heat sink are considered. Classification of welding processes with heat removal by the technological and physical features, is proposed. It is found that for up to 3mm thick metal the most effective is the application of the heat-absorbing pastes and crystalline heat-absorbing rods, and for 3-8mm thick metal it is water cooling. Welding with heat sink should be regarded as a resources-saving proces
Keywords: welding, stress, strain, heat removal, artificial, devices, methods
