Inspection of Austenitic Stainless Steel, Cladded Welds, Dissimilar Metals and Alloys
The ultrasonic inspection of Austenitic Stainless Steels, Corrosion Resistant and Super Alloys, Dissimilar Metals, and similar or related processes can be difficult. The use of these materials is on the rise in several industries due to their material properties.
Inherent material properties cause beam skewing and scattering, signal attenuation and poor signal to noise ratio, lack of skip at interfaces and other complications to the ultrasonic inspection process. Potential effects of grain properties on different ultrasonic beam modes will be explored in detail.
New phased array solutions are offering resources to overcome these difficult roadblocks to successful volumetric ultrasonic inspection of these types of materials with easy to use and lower cost solutions for all ultrasonic inspector levels. The best practice use of common 1D linear array probes, dual arrays and matrix arrays will be outlined along with sample application and comparison data to highlight the successful ultrasonic inspection of these challenging materials. Benefits of a phased array approach will outlined along with potential obstacles to successful inspection. Detailed inspection technique options will be reviewed side by side.
