The non-destructive testing of austenitic stainless steel welds of the primary coolant pi**
system is a significant problem for the nuclear industry. Ultrasonic techniques would be very …

Conventional ultrasonic detection methods are commonly used for detecting austenitic
stainless steel weld structure. The anisotropy and inhomogeneity of the weld produces a …

Multipass welds made in austenitic stainless steel, in the primary circuit of nuclear power
plants with pressurized water reactors, are characterized by an anisotropic and …

Ultrasonic testing of austenitic welds prepared by two different welding processes is studied
in this paper. The two welding processes considered are shielded metal arc welding …

Phased array ultrasound testing (PAUT) can produce steerable and tightly focused
ultrasonic beams, so it is widely used for detecting flaws. However, inspection of dissimilar …

Ultrasonic inspection of austenitic welds is challenging due to their highly anisotropic and
heterogeneous microstructure. The weld anisotropy causes a steering of the ultrasonic …

Abstract A coupled Cellular Automaton (CA)–Finite Element (FE) model is proposed to
predict the grain structure formation during Gas Tungsten Arc Welding (GTAW). The FE …

A finite element modeling approach of ultrasonic propagation combined with a description of
the microstructure at the scale of the grains has been implemented. The simulations seek to …

In order to improve the performance of defect sizing and locating in the ultrasonic inspection
of austenitic welds, it is important to predict ultrasonic propagation paths using ray-tracing …

Ultrasound propagation in inhomogeneous anisotropic materials is difficult to examine
because of the directional dependency of elastic properties. Simulation tools play an …
