"1. Scope, 1.1 This practice describes ultrasonic techniques for inspecting welds using phased array ultrasonic methods (see Note 1)." ; "Note 1--This practice is based on experience with ferrous and aluminum alloys. Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can be successfully penetrated by an ultrasonic beam."

Described is a manual, portable non-destructive technique to determine the through wall height of cracks present in dissimilar metal welds used in the primary coolling systems of pressure water and boiler light water reactors. Current manual methods found in industry have proven not to exhibit the sizing accuracy required by ASME inspection requirement. The technique described demonstrated an accuracy approximately three times that required to ASME Section XI, Appendix 8 qualification.

TFM implementation was adapted to support the usage of Transmit Receive Longitudinal (TRL) ultrasonic probes. A new algorithm was developed to correct for ultrasonic wave velocity variations caused by anisotropic material properties of Corrosive Resistant Alloy (CRA). Experimental testing was conducted on an XRD verified Austenitic Stainless-Steel girth weld sample. A cut-section macrographic image of the weld showing grain orientation and distribution was obtained. Ultrasonic wave velocity when pulse passes normal and parallel to weld grains are measured. The challenges in using TRL probes for TFM delay computation, including curved surface and 3D ray-tracing are addressed. A benchmarking sample was manufactured. The adapted TFM implementation was compared with an industrial phased array scanner. Comparison shows improved resolving capabilities and noise reduction with TFM compared with standard phased array. A velocity correction algorithm is proposed, where individual rays from TFM are analyzed and corrected based on the weld grain structure.

This open access book presents established methods of structural health monitoring (SHM) and discusses their technological merit in the current aerospace environment. While the aerospace industry aims for weight reduction to improve fuel efficiency, reduce environmental impact, and to decrease maintenance time and operating costs, aircraft structures are often designed and built heavier than required in order to accommodate unpredictable failure. A way to overcome this approach is the use of SHM systems to detect the presence of defects. This book covers all major contemporary aerospace-relevant SHM methods, from the basics of each method to the various defect types that SHM is required to detect to discussion of signal processing developments alongside considerations of aerospace safety requirements. It will be of interest to professionals in industry and academic researchers alike, as well as engineering students. This article/publication is based upon work from COST Action CA18203 (ODIN - http://odin-cost.com/), supported by COST (European Cooperation in Science and Technology). COST (European Cooperation in Science and Technology) is a funding agency for research and innovation networks. Our Actions help connect research initiatives across Europe and enable scientists to grow their ideas by sharing them with their peers. This boosts their research, career and innovation.

This Handbook compiles advanced methods for materials measurement and characterization from the macroscopic to the nano-scale. Materials professionals need not only handbooks of materials data but clear guidelines and standards for how to measure the full spectrum of materials characteristics of new materials ans systems. Since materials science forms a bridge between the more traditonal fields of physics, engineering, and chemistry, unifying the varying perspectives and covering the full gamut of properties also serves a useful purpose. This handbook is the first dedicated to these practical and important considerations.
