Development of a phased array ultrasound roller probe for inspection of wire + arc additive manufactured components

Vithanage, Randika K. W.; Mohseni, Ehsan; Lines, David; Loukas, Charalampos; Foster, Euan; MacLeod, Charles N.; Pierce, S. Gareth; Gachagan, Anthony; Ding, Jialuo; Williams, Stewart (Elsevier, 2022-06-25)

The wire + arc additive manufacturing (WAAM) process, which combines an electric arc as a heat source and metal wire as feedstock is proving to be very effective when producing medium to large scale metal components. The ...
Multi-layer ultrasonic imaging of as-built wire + arc additive manufactured components

Zimermann, Rastislav; Mohseni, Ehsan; Lines, David; Vithanage, Randika K. W.; MacLeod, Charles N.; Pierce, Stephen G.; Gachagan, Anthony; Javadi, Yashar; Williams, Stewart; Ding, Jialuo (Elsevier, 2021-10-13)

Non-Destructive Evaluation (NDE) of metal Additively Manufactured (AM) components is crucial for the identification of any potential defects. Ultrasonic testing is recognised for its volumetric imaging capability in metallic ...
Remote ultrasonic imaging of a wire arc additive manufactured Ti-6AI-4V component using laser induced phased array

Lukacs, Peter; Davis, Geo; Stratoudaki, Theodosia; Williams, Stewart; MacLeod, Charles N.; Gachagan, Anthony (IEEE, 2021-06-28)

Additive manufacturing (AM) has been revolutionizing the manufacturing industry due to its ability to significantly reduce waste and produce components with intricate shapes. Laser Ultrasonics (LU) is a non-contact and ...
Ultrasonic phased array inspection of wire plus arc additive manufacture samples using conventional and total focusing method imaging approaches

Javadi, Yashar; MacLeod, Charles N.; Pierce, Stephen G.; Gachagan, Anthony; Lines, David; Mineo, Carmelo; Ding, Jialuo; Williams, Stewart W.; Vasilev, Momchil; Mohseni, Ehsan; Su, Riliang (British Institute of Non-destructive Testing, 2019-03-01)

In this study, three aluminium samples produced by wire + arc additive manufacture (WAAM) are inspected using ultrasonic phased array technology. Artificial defects are machined using a centre drill, ø 3 mm, and electrical ...
