1. Introduction

This instrument is a portable industrial digital ultrasonic flaw detector that can detect, locate, evaluate and diagnose various defects (cracks, inclusions, pores, etc.) in the workpiece quickly, conveniently, without damage, and accurately. It can be used both in the laboratory and on the engineering site. This instrument can be widely used in manufacturing, iron and steel metallurgy, metal processing, chemical industry and other fields that require defect detection and quality control. It is also widely used in online safety inspection and Life assessment in the fields of aerospace, railway transportation, boilers and pressure vessels, etc.

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.

2. Functions

2.1 Auto calibration: Automated calibration of probe zero offset, probe angle (K value) and material velocity.

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

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

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

2.5 DAC/AVG: The curve is automatically generated, and the sampling points can be compensated and corrected. The curve automatically floats with the gain, automatically expands with the detection distance, and automatically moves with the delay time. It can display the AVG curve of any aperture.

2.6 AWS D1.1. Choosing this standard can reduce manual calculations and improve detection efficiency.

2.7 Curved Surface Correction feature.

2.8 Crack Height Measure function.

2.9 Gate Magnify: spreading of the gate range over the entire screen width.

2.10 Video Recording and playback.

2.11 Auto-gain function

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

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

2.14 Peak mark: capture and mark the peak in real time

2.15 Echo coding: display 1~9 echo display area in different colors, used to analyze the defect position.

2.16 A Scan Freeze: Display freeze holds waveform and test distance data.

2.17 B Scan display feature. Intuitively display the defect shape of the workpiece and the detection result is more intuitive.
