Sound Incident Angle
The angle of incidence is the angle at which an ultrasound beam hits a surface. It determines the direction of reflection and transmission of the beam.
Physical-Chemical Mechanism of Action
The sound incidence angle is the angle between the incoming beam of an ultrasonic wave and the surface it strikes. This angle determines whether the beam is reflected or transmitted.
Metallurgical Relevance & Welding Risks
An incorrect sound incidence angle can lead to inaccurate measurements and false results. This can cause misjudgments and misunderstandings when inspecting cracks, hardness distribution, or other quality parameters.
Workshop Practice & Action Instructions
Make sure the ultrasonic beam hits the surface perpendicularly (sound incidence angle = 0°). This increases measurement accuracy. For precise inspections, use special transducers and holders to control the angle exactly.
