Precautions when purchasing an ultrasonic flaw detector

Ultrasonic Flaw Detector is a portable industrial non-destructive testing instrument that can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece quickly, easily, without damage and accurately. It can be used in both laboratories and engineering sites. Widely used in boilers, pressure vessels, aerospace, aviation, electric power, petroleum, chemical, offshore oil, pipeline, military, shipbuilding, automotive, machinery manufacturing, metallurgy, metal processing industry, steel structure, railway transportation, nuclear power, universities, etc. industry.

The following small series talk about the precautions when purchasing an ultrasonic flaw detector

1. When the probe is not connected, the gain is adjusted to the maximum, and the waveform on the screen cannot exceed 10% of the screen. If it is exceeded, the instrument fails.

2, see if vertical linearity is qualified, method

3. There are also some indicators that require a dedicated test block. It is recommended that the new instrument be sent to the provincial metrology test station for identification to avoid being fooled.
