Radiographic Testing-RT

Principals:

Differential absorption of radiation by the object gives density variation in the film...

Equipment Needs:

Gamma ray sources, amma ray camera projectors, film holders, film, lead screens, film processing equipment, film viewers, exposure facilities, radiation monitoring equipment.

Application:

Welds which have voluminous discontinuities such as porosity, incomplete joint penetration, corrosion, etc, Lamellar type iscontinuities such as cracks and incomplete fusion can be detected with a lesser degree of reliability. May also be used in certain applications to evaluate dimensional requirements such as fit-up, root conditions and wall thickness.

Advantages:

Generally not restricted by type of material or grain structure. Surface and sub surface inspection capability .Radiographic images aid in characterizing discontinuities. Provides a permanent record for future review.

Limitation:

Planar discontinuities must be favorably aligned with radiation beam to be reliably detected, radiation poses a potential hazard to personnel. Cost radiographic equipment, facilities, safety programs and related licensing is relatively high. A relatively long time between exposure process and availability of results. Accessibility to both sides of the weld required..
