Abstract
The strength of austenitic welds will be considerably reduced if cracks are present. To guard against this possibility good workmanship is essential; quality is monitored by inspecting the welds after manufacture. Ultrasound is the favored method of inspection but there are difficulties associated with this in the coarse-grained columnar weld structures often associated with austenitic materials. We present two different approaches to modeling such inspections: ray tracing and full numerical solution of the governing wave equation. We show that the two approaches, although very different in physical nature and numerical method, give similar and consistent results.
