STUDY OF THE STRUCTURE AND MECHANICAL PROPERTIES OF A WELD IN A HEAT EXCHANGER BY COMPUTER MODELING

摘要

This article examines the effect of the welding of steel 15Kh5M on the formation of local thermal stresses in a weld formed between a tube and the tube array of a shell-and-tube heat exchanger. The study was performed by computer modeling of the welding operation with the use of the finite-elements method.
