Ultrasonic testing is a non-destructive and safe method widely used in manufacturing and service industries, particularly for welds and structural metals. It includes techniques like ultrasonic flaw detection and pulse velocity testing to assess the quality and integrity of materials, especially concrete. Factors influencing pulse velocity in concrete include path length, specimen size, reinforcement, and moisture content.

2. Ultrasonic testing is completely nondestructive
and safe, and it is a well established test
method in many basic manufacturing,
process, and service industries, especially in
applications involving welds and structural
metals.

3. Ultrasonic Flaw Detection Test :
Ultrasonic testing is completely nondestructive
and safe, and it is a well established test
method in many basic manufacturing,
process, and service industries, especially in
applications involving welds and structural
metals.

4. Ultrasonic Pulse Velocity Test :
Ultrasonic concrete testing is based on the
pulse velocity method to provide information
on the uniformity of concrete, cavities, cracks
and defects. The pulse velocity in a material
depends on its density and its elastic
properties which in turn are related to the
quality and the compressive strength of the
concrete.

5. 
The pulse velocity in concrete may be
influenced by
a) Path length
b) Lateral dimension of the specimen tested
c) Presence of reinforcement steel
d) Moisture content of the concrete
