AFD856 Ultrasonic Flaw Detector

Introduction

The AFD856 is an advanced digital ultrasonic flaw detector featuring a multi-color TFT LCD and a host of new features to meet challenging inspection requirements. It combines powerful flaw detection and measurement capabilities, extensive data storage, and the ability to transfer detailed inspection data to the PC via its full-speed USB port.

The instrument incorporates many advanced signal processing features including a 15MHz RF bandwidth to permit testing of thin materials, narrowband filters to improve signal to noise in high gain applications, a spike pulser for applications requiring higher frequencies, and a tunable square wave pulser to optimize penetration on thick or highly attenuating materials.

The instrument can be widely used in locating and sizing hidden cracks, voids, disbands, and similar discontinuities in welds, forgings, billets, axles, shafts, tanks and pressure vessels, turbines, and structural components.
Features

Ø Calibration wizard for correcting the transducer zero offset and/or material velocity

Ø Flaw Locating: Live display Sound-path, Projection (surface distance), Depth, Amplitude,

Ø Flaw sizing: Automatic flaw sizing using AVG/DAC, speeds reporting of defect acceptance or rejection.

Ø Digital Readout and Trig. Function: Thickness / Depth can be displayed in digital readout when using a normal probe and beam path, Surface Distance and Depth are directly displayed when angle probe is in use.

Ø Both the DAC and the AVG method of amplitude evaluation are available.

Ø Curved Surface Correction feature

Ø Crack Height Measure function

Ø Weld figure feature

Ø Magnify gate：Spreading of the gate range over the entire screen width

Ø Video record and play

Ø Auto-gain function

Ø Envelope: Simultaneous display of live A-scan at 60 Hz update rate and envelope of A-scan display

Ø Peak Hold: Compare frozen peak waveforms to live A-Scans to easily interpret test results.

Ø Leg band function: Helps to identify the legs of the echo more clearly in angle beam inspection.

Ø A Scan Freeze：Display freeze holds waveform and sound path data

Ø B Scan feature

Ø AWS D1.1/D1.5 wizard

Ø Selftest wizard: Selftesting of horizontal linearity, vertical linearity, resolution, dynamic range and sensitivity.
