Final answer:
The ball catchers view is a radiographic technique used to assess the quality of welds by highlighting imperfections or discontinuities.
Step-by-step explanation:
The term ball catchers view is commonly used in the context of radiographic testing of welds. When assessing the quality of welds using radiographic imaging, a ball catchers view is particularly helpful. This method involves placing a radiographic film on one side of the weld and a small ball or similar object on the opposite side. When x-rays pass through the weld, the ball creates a shadow that helps to highlight the presence of any imperfections or discontinuities within the weld.
In answering the question, "Ball catchers view is good to assess what?", the correct option would be B) Weld quality. It provides a clear image that can reveal defects such as cracks, voids, and inclusions that might compromise the integrity of the weld. Pipe alignment or surface finish are not typically assessed using this radiographic technique.
