Question

1. a black light with a fluorescent liquid is used in the inspection method. a. visual b. radiograph c. dye penetrant d. magnetic particle e. all of the above 2. testing is a dynamic test in which the weld is broken by a single blow. a. etch b. tensile c. shear d. guided - bend e. none of the above 3. a weld is tested for soundness by applying force with a press, a testing machine, or hammer blows. a. pipe b. butt tensile c. nick - break d. charpy e. fillet 4. the quickest way to test welds. a. destructive b. nondestructive c. visual d. all of the above

Explanation:

1. A black light with a fluorescent liquid is used in visual inspection for detecting surface - opening defects.
2. A dynamic test where the weld is broken by a single blow is shear testing.
3. Applying force with a press, a testing machine, or hammer blows to test a weld for soundness is a destructive test. Among the options, nick - break is a destructive test for welds.
4. Visual inspection is often the quickest way to test welds as it can be done rapidly without complex equipment or sample preparation.

Answer:

1. A. visual
2. C. Shear
3. C. nick - break
4. A. visual
