Abstract

Waist welds on spherical experimental pressure vessels have been evaluated under pressure using holographic interferometry. A coincident viewing and illumination optical configuration coupled with a parabolic mirror was used so that the entire weld region could be examined with a single hologram. Positioning the pressure vessel at the focal point of the parabolic mirror provides a relatively undistorted 360 degree view of the waist weld. Double exposure and real time holography were used to obtain displacement information on the weld region. Results are compared with radiographic and ultrasonic inspections.

Holographic nondestructive evaluation of spherical kevlar/epoxy pressure vessels

Conference Boyd, D; Maxfield, B

Three spherical kevlar/epoxy pressure vessels were evaluated using holographic interferograms provide information on the failure modes, displacement profile, and possible fiber damage. The holograms show a symmetric anisotropic displacement pattern even though the vessels failed due to a leak in the aluminum mandrels. The presence of a biconvex fringe pattern found during the testing of vessel three is believed to indicate matrix crazing. This information would be useful for burst type failure analysis. Holographic interferometry has been shown to supply information on the characteristics of kevlar/epoxy pressure vessels under stress.
Application of holographic interferometry to the inspection of HERF stainless steel pressure vessels

Conference Tichenor, D; Henry, K; Gorman, R

Holographic interferometry has been demonstrated as a useful technique for inspecting small stainless steel pressure vessels machined from High Energy Rate Forged (HERF) material. This multistep forging process alters the mechanical properties of the material as the part is formed. Errors in the forging process can result in local or uniform reductions in tensile strength. Flaws of this type increase the amount of residual deformation which occurs as a result of pressure testing. Holographic interferometry is well suited to the measurement of the residual deformation because: (1) the deformations of interest are very small, and (2) the entire surface ofmore »« less
Holographic determination of the yield strength of a welded stainless steel pressure vessel

Technical Report Meyer, M.

The strength and toughness of a high energy rate formed (HERF'ed) stainless steel, as influenced by the heat input from a variety of welds, are being measured. Using holographic interferometry, a welded spherical pressure vessel constructed from HERF'ed stainless steel with a composition of 21 percent Cr, 6 percent Ni, 9 percent Mn, 0.23 percent N, balance Fe was examined. Holographic examination of the weld vicinity shows that plastic deformations in the heat affected zones reach a maximum at a distance of 5 mm on either side of the weld, and tails off for another 20 mm to zero strain.more »« less

Application of holographic interferometry in the detection of flaws in composite plates

Conference Tay, T; Shang, H; Lwin, M

The use of holographic interferometry in the detection of sub-surface flaws in structural components offers certain advantages, including the ability to obtain full-field inspection without the necessity for physical contact. However, the resulting fringe patterns obtained must be carefully analyzed in order to derive meaningful interpretations. In this paper, the technique of holographic interferometry was applied to the assessment of defects in glass fiber-reinforced composite and aluminum plates. Circular plate specimens were clamped along the boundaries and an incremental pressure was applied between two exposures to obtain holograms. The defects, in the form of locally thinned regions, cause perturbations inmore »« less
Half-bead (temper) repair welding for heavy-section steel technology program vessels

Technical Report Wismer, S; Holz, P

The ''half-bead (temper) welding technique'' performed to Section XI of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code guidelines was used successfully on cavities placed in three thick-walled pressure vessel models to simulate repair welding of operational nuclear reactor vessels. One of the models served as a qualification-procedure test specimen, as required by the Code, and was subsequently utilized for detailed metallurgical examinations. The temper-, or half-bead, technique, in theory, is structured such that each weld pass is applied in a manner which results in tempering the preceding weld pass. Thus, brittle transformation products created duringmore »« less
