Релаксация сварочных напряжений при помощи глубокого пластического деформирования

Abstract

В работе рассмотрен способ снижения уровня остаточных напряжений в сварных конструкциях путем обработки области сварного шва с помощью глубокой пластической деформации. Описаны результаты эксперимента, а также расчета при помощи конечно-элементного пакета ANSYS Workbench, показывающие возможность применения метода для снижения уровня остаточных сварочных напряжений. A method for reducing the level of residual stress of welded structures by treatment of the weld with deep local plastic deformation is offered. The results of the experiment and calculation using finite element program complex ANSYS Workbench show the feasibility of applying the method to reduce the level of residual welding stresses.
