How Does Ultra Sonic Testing Work? |
|
Answer» High frequency SOUND waves are very directional, and they will travel through a medium (like a piece of STEEL or plastic) until they ENCOUNTER a boundary with another medium (like air), at which point they reflect back to their source. By analyzing these REFLECTIONS it is possible to measure the thickness of a test piece, or find evidence of cracks or other hidden INTERNAL flaws.
