The guide track assembly is rigidly coupled to the ultrasonic scanning apparatus in the axial direction, but allows rotational motion of the ultrasonic scanning apparatus directly along the outer surface of the conduit using a drive chain that is driven by a circumferential drive. Secure rotational motion without drift between the guide track assembly and the ultrasonic scanning apparatus is maintained by the rigid coupling and by a spring-loaded wheel housing assembly that maintains contact of wheels that travel along the guide track. The ultrasonic scanning apparatus includes a transducer with spring-loaded gimbaling that maintains optimal proximity with the conduit surface. The transducer is translated axially along linear journals that extend along the conduit with a linear actuator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circumferential weld scanner with axial drift prevention","description":"Inspection of circumferential sections of pipe or other conduit using an ultrasonic scanning apparatus is provided, wherein axial drift of the ultrasonic scanning apparatus is prevented using a guide ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8485036","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.
