Inspection of austenitic steel welds has been performed for many years with varying success. With refinement to our knowledge of the effects of the weld process, and greater awareness of the effects of the material grain structure on our sound fields, we can now more confidently approach these often-challenging inspections. With a potentially wide range of materials being joined it is critical to approach each inspection with a level of caution. Inspectors are now equipped with many new tools, improved instrumentation, a wide range of transducers, and software which includes predictive modeling. This paper will convey several logical steps to be performed in order to ensure the success of the inspection. Founded on initial findings, the technician will be able to assemble a virtual check list of steps that will ensure they can convey validation and demonstration of the developed technique.
