Ultratovush tekshiruvida nur yo'li uzunligi nima?

Beam path is the distance the ultrasonic wave travels from the probe to the reflector. For angle beam: beam path = thickness / cos(angle). For the full V-path (skip): beam path = 2 × thickness / cos(angle).

O'tish masofasi nima?

Skip distance is the surface distance between the probe entry point and where the beam reflects off the back wall. Full skip = 2 × thickness × tan(angle). Half skip = thickness × tan(angle). Used for weld inspection positioning.

Yaqin maydon uzunligi nima?

Near field (Fresnel zone) N = D²f/(4v) where D = probe diameter, f = frequency, v = velocity. Within the near field, the beam has uneven pressure distribution. Inspections should be done beyond N for reliable results.

Zond burchagi tekshiruvga qanday ta'sir qiladi?

Common angles: 0° for thickness measurement, 45° for detecting vertical flaws in welds, 60° for general weld inspection (most common), 70° for thin materials and near-surface flaws. Angle refers to refracted shear wave angle in the test material.

Ultratovush tekshiruvi uchun qanday chastotani tanlash kerak?

Yuqori chastota = yaxshiroq aniqlik, ammo kam kirib borish chuqurligi. 1–2 MGts — quyma va yirik donali materiallar uchun. 2–5 MGts — po'lat mahsulotlarini umumiy nazorat qilish uchun. 5–10 MGts — yupqa materiallar va yuqori aniqlik uchun. 10–25 MGts — aniq o'lchash uchun.

Amaliy Misol

Misol — 25 mm uglerodli po'latda 60° burchakli nur

V_shear = 3250 m/s, t = 25 mm, θ = 60°

Half skip = 25 × tan(60°) = 25 × 1.732 = 43.3 mm

Full skip = 2 × 43.3 = 86.6 mm

Beam path = 2 × 25 / cos(60°) = 50 / 0.5 = 100 mm

N = 20² × 4×10⁶ / (4 × 3250) = 1600000/13000 = 123 mm

λ = 3250 / (4×10⁶) × 1000 = 0.81 mm
