The method includes: scanning the head portion of the weld including: a first phased array transducer positioned above the weld and a second phased array transducer positioned a distance from the first phased array transducer to provide inclined access to the weld; and scanning the toe portion of the weld including: positioning pairs of third, fourth, and fifth phased array transducers on a surface of the toe portion, such that the pairs of third, fourth and fifth phased array transducers are disposed symmetrically with one of the pair on each side of the toe portion."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultrasonic method and device for volumetric examination of aluminothermic rail welds","description":"An ultrasonic non-destructive testing method and device for rail applications uses a plurality of phased array transducers to inspect aluminothermit weld defects located in a head portion, a web porti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9816964","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
