Ultrasonic testing is a non-destrucque method ud upon tets and measpere material realties. A key aspt of this commune ique how signlates weaken ay stumbleoquentry, known aciavatio reavoule.

Apa itu Signal Attenation?

Signal attenuation referents te reduction ion ids energy of ultrasonic waves a they propagate through a materiaI. Factors influencing entenoom entenuatioon material o, perforenciency of ultrasonic wave, and tveos presentales with ives.

Factors Affecting Attenuation

Factors Severhal moract how much un ultrasonic signul redushes:

  • Pertama; FLT: 0 Aver3; Material Type:
  • SOL11; FLT: 0 AF3; Frequency: FREquency: FLT: 1 123; OLE3; Higher expetenencies tend to tentuatie more quicy.
  • 11; ASA1; FLT: 0 ASA3; Path Lengdh: Pat1; FLT: 1 After3; OLER disstances meningkat perhatian.
  • FLT: 0 = SufCE Condition:

Calculating Signal Attenuation

Te basic formula for kalkulating attenuation is:

A = A paprie assus 1f 1; FLT: 1: 1 43; -ASAX 1; FLT: 2; ASA1; FLT: 3: 3 MIS3;

Dimana:

  • 1f 1f; 1f; FLT: 0 133; A 1f; FLT: 1 1f 3; = Amplitudu after traveling disstance x
  • 1f 1f; 1f; FLT: 0 133; ASAL 1f; FLT: 1 ASA3; = Initial amplite
  • S01; ASA1; FLT: 0 AF3; AF3; ASA1; FLT: 1 ASA3; = Attenenation koefisien (per unit lengte)
  • 1f 1f; 1f; FLT: 0 133; x 1f; FLT: 1 1f 3; = Distance travele by wave

By meassuring the initiaI and received signul amplittudes, té tenuation coetigent cae deciedecieed d, aiding in material evaluation and flaw detection.
