AWS Certified Radiographic Interpreter (CRI) Examination Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• Which type of radiographic film is most commonly used for welding

inspection?

• D-speed
• F-speed
• G-speed
• H-speed

D-speed films are preferred in welding inspection because they provide higher image sharpness and resolution for detecting discontinuities. 1 / 4

2. In radiography, a penetrameter (IQI) is used to:

• Adjust the exposure time
• Assess the sensitivity of the radiograph
• Focus the X-ray beam
• Develop the film

The penetrameter, or Image Quality Indicator, measures the ability of the radiograph to reveal fine details and discontinuities.

• What is the primary hazard associated with radiographic inspection?
• Noise
• Heat
• Radiation exposure
• Electrical shock

Radiographic inspection involves X-rays or gamma rays, which pose a risk of radiation exposure if proper safety precautions are not followed.

• Which discontinuity is characterized by a surface-breaking linear

indication?

• Porosity
• Slag inclusion
• Crack
• Lack of fusion

Cracks appear as sharp, linear features that often break the surface, making them critical defects. 2 / 4

• When inspecting a weld using gamma rays, increasing the distance

between the source and the weld:

• Decreases exposure time
• Reduces radiation intensity on the film
• Improves sensitivity
• Increases film density

Radiation intensity decreases with the square of the distance, requiring adjustments in exposure to maintain image quality.

6. The primary advantage of digital radiography over conventional film is:

• Lower cost
• Immediate image acquisition and processing
• No radiation required
• Less operator skill

Digital radiography allows for instant evaluation of the image, eliminating the need for film development.

7. In radiographic interpretation, a “fogged” film indicates:

• Correct exposure
• Excessive exposure or poor storage
• Proper penetration
• Sharp imaging

Fogging reduces image contrast and can result from overexposure, scattered radiation, or improper storage conditions. 3 / 4

• Which type of radiation source is commonly used for radiography of

thick steel welds?

• Alpha particles
• Beta particles
• Cobalt-60
• Ultraviolet light

Cobalt-60 emits high-energy gamma rays capable of penetrating thick metal sections effectively.

9. The term “contrast” in radiography refers to:

• Total film density
• The difference in film density between adjacent areas
• Exposure time
• Source-to-film distance

Contrast is critical for distinguishing between discontinuities and sound material.

• Which film orientation is recommended to detect longitudinal

cracks in a weld?

• Perpendicular to the crack
• Parallel to the crack
• At a 45° angle
• Random orientation

Aligning the X-ray beam parallel to the suspected crack maximizes the visibility of longitudinal defects.
