An ultrasonic methodology to non-destructively estimate the grain orientation in an anisotropic weld

An ultrasonic methodology to non-destructively estimate the grain orientation in an anisotropic weld

The initial step towards a non-destructive technique that estimates grain orientation in an anisotropic weld is presented in this paper. The purpose is to aid future forward simulations of ultrasonic NDT of this kind of weld to achieve a better result. A forward model that consists of a weld model,...
