壓力容器銲道自動超音波檢測-PAUT 與 TOFD (Auto Ultrasonic Testing for Welds, PAUT and TOFD)

根據ASME Code Case 2235，針對壁厚70mm~160mm的壓力容器銲道，以相位陣列超音波檢測取代輻射照相檢測，更利用自動掃描裝置實施自動化相位陣列超音波檢測，可快速且穩定地完成銲道及其熱影響區檢測工作。

ASME Code Case 2235 : Use of Ultrasonic Examination in Lieu of Radiography Section I; Section VIII, Divisions 1 and 2; and Section XII-2009 

Using the phased array ultrasonic testing for full penetration welds and its heat-affected zone in carbon steel and alloy steel of pressure vessel, boiler and fabricated parts with thickness ranging from 70 mm to 160 mm.
