Filed:

Nov 30, 2004

Appl. No.:

10/999470

Inventors:

Peter K. Hwang - Kent WA, US

Assignee:

The Boeing Company - Chicago IL

International Classification:

B21D 39/20

US Classification:

72 58, 7237008, 724668

Abstract:

An apparatus and method including a die assembly and tooling, which includes a draw bolt and coaxially disposed expandable element. When control of the apparatus is initiated the die assembly and draw bolt retract or move down over the work piece until the die assembly is seated in the die holder. The draw bolt continues to move down which causes the elastomer insert to expand and push the work piece outwardly forcing the work piece to conform to the contour of the die assembly creating the desired transition diameter.

International Classification:

G01N 29/04

US Classification:

73628

Abstract:

An apparatus for inspecting a tubular workpiece may include a probe assembly and a rotation mechanism. The probe assembly may include a transducer array positionable adjacent to an inner surface of the tubular workpiece. The probe assembly may generate transmitted sound waves and may receive reflected sound waves. The rotation mechanism may rotate the probe assembly relative to the tubular workpiece in a manner such that the transducer array passes over the inner surface in a circumferential direction during transmission of the transmitted sound waves.
