Neutron Diffraction Strain Measurement during TIG Welding

Abstract:

Development of hot cracks during welding of austenitic materials is a challenge which must be coped with when a suitable welding method is to be chosen. Boundary conditions about hot crack formation are not sufficiently known. One factor is the state of strain during welding. Therefore strain is determined via neutron diffractometry next to the fusion line during welding. This evaluation shall allow to draw conclusions about the influence of the state of thermal strain on the hot crack formation.
