Praktek UT. 4-Membuat Kurva DAC Pakai IOW Block

Langkah Dasar praktek UT

Kalau buat DAC dari pipa 1/2 lingkaran bagai mana om

[@w.ruswandi636]

Kalo teknis pembuatan kurve DAC itu sama semua.. Yang penting kurva itu terbentuk dari reflectors yg sama bentuk dan ukurannya.. Misalkan didalam pipa 1/2 lingkaran itu yg ada nya SDH, maka buat kurva DAC nya dari SDH itu... Atau kalau yg adanya notches, maka kurva DAC nya yaa diambil dari notch.. Semua ditentukan oleh procedure yg akan kita gunakan... Terima kasih.

Bang, misalkan kita mau scan material 24 mm sedangkan kita punya block kalibrasi 19 mm. Itu setting DAC nya iku mana? 19 atau 24 mm? makasih.

Sir ....I have a question for you ....when we calibrate we start with 1/4 then1/2 then 3/4 hole Please explain this point

Hi @AL, In the principal, DAC curve is used for acceptance references to judge the funded indications are still accepted or rejected. The technique to construct DAC curve is NOT always use SDH 1/4, 1/2, 3/4 etc… Its depending to our spec/procedure. Maybe some time we use Notches for our reflectors. But the DAC principles is Always constructed from reflector that same size and dimension. And first point take from the shortest distance, than continues to more far in distance. For example; such you say, first take from 1/4 than 1/2 than 3/4. Hopefully you can catch my explanation

Setiap spec itu requirement-nya berbeda-beda. Ada yg mensyaratkan harus sama thickness dengan block-nya, ada juga yg satu thickness block bisa mewakili untuk beberapa thickness yg akan kita uji. Jadi kita kembalikan ajaa ke procedure yg kita pakai Mas..
