When field technicians operate portable ultrasonic flaw detector for industrial non-destructive testing, they always wonder: which hidden internal flaws can digital NDT equipment accurately locate and quantify? Traditional ordinary ultrasonic flaw testers often suffer from unstable echo signals, short battery life and incomplete quantitative functions, which easily lead to missed detection of dangerous defects in workpieces. The iFlaw-100 Ultrasonic Flaw Detector, Mikrosize’s flagship lightweight industrial flaw testing machine, solves all pain points of on-site ultrasonic flaw testing and adapts to all mainstream industrial inspection scenarios.
1. What Is The Core Working Principle Of Ultrasonic NDT Flaw Inspection Equipment
As the basic theory of ultrasonic testing records, all digital ultrasonic flaw detector rely on the propagation law of ultrasonic waves inside solid materials. The acoustic characteristics and internal tissue structure of the workpiece will change the transmission state of sound waves; technicians analyze the position, amplitude and waveform of reflected echoes to judge the depth, size and type of internal defects.
Three mainstream detection methods supported by all industrial ultrasonic flaw testing machine:
- Pulse reflection method: The most widely used mode for one-handed portable flaw tester, uses a single probe to transmit and receive ultrasonic pulses to capture flaw echoes and bottom wave signals, suitable for welds, forgings and pressure vessels.
- Penetration method: Dual-probe transceiver testing, mainly applied to thin plate batch flaw screening.
- Resonance method: Auxiliary thickness measurement while detecting layered defects inside materials.
Four wave modes match different inspection targets, which the iFlaw-100 Ultrasonic Flaw Detector fully supports through adjustable bandwidth parameters:
- Longitudinal wave: Detect inclusions, shrinkage cavities and lamination of thick castings and steel ingots
- Shear wave: Identify weld pores, slag inclusions, incomplete penetration and pipeline axial/ circumferential cracks
- Surface wave: Capture tiny microcracks on the surface of precision mechanical parts
- Plate wave: Defect screening for thin metal sheets
2. 7 Common Troubles When Using Ordinary Ultrasonic Flaw Detector On Site
Many inspectors complain that low-cost industrial flaw detection equipment brings constant testing errors during daily inspection, the core problems are summarized below:
- Unstable clutter echoes without multi-level filtering functions, unable to separate real defect signals;
- Lack built-in DAC & AVG curve quantitative functions, cannot evaluate flaw size complying with international and national testing standards;
- Short battery life (only 4–6 hours), unable to support all-day outdoor continuous scanning for pipelines and steel rails;
- Small monochrome screen + complicated physical buttons, hard to operate under strong sunlight;
- No B-scan imaging and multi-frame recording function, cannot store complete waveform data for quality traceability;
- Narrow fixed bandwidth, cannot match low-frequency penetration probes for thick workpieces and high-frequency probes for microcrack detection;
- Substandard metrological performance, resulting in large deviation of defect depth measurement.
All the above pain points are completely optimized on Mikrosize iFlaw-100 Ultrasonic Flaw Detector, a professional touch screen NDT flaw tester designed for full-industry field testing.
