The ultrasonic flaw detector is a portable industrial nondestructive flaw detection instrument, which is mainly used to detect various defects inside the workpiece, such as cracks, looseness, pores and inclusions, and to locate, evaluate and diagnose. It can be detected quickly, conveniently and non-destructively, and is widely used in laboratories and engineering sites. The detection principle of the ultrasonic flaw detector is to use the characteristics of ultrasonic waves that will reflect when encountering different interfaces when propagating in the medium, and detect the defects inside the workpiece through the reflected wave.
The specific application fields of ultrasonic flaw detectors are very wide, including but not limited to the following industries:
Boilers and pressure vessels: used to detect defects inside boilers and pressure vessels to ensure their safe operation.
Aerospace and aviation: In the field of aerospace, it is used to detect internal defects of aircraft and rocket components.
Electricity and petroleum: In the power and petroleum industries, it is used to detect internal defects of pipelines and equipment.
Chemical and metallurgy: Used for metal processing equipment and containers in the chemical and metallurgical industries.
Shipbuilding and automobiles: Used in the manufacturing process of ships and automobiles to detect welding and material defects.
Railway transportation: In the field of railway transportation, it is used to detect internal defects of railway equipment and tracks.
Colleges: In colleges and universities, it is used for teaching and research to help students understand the principles and applications of non-destructive testing.
The technical parameters of ultrasonic flaw detectors include scanning range, operating frequency and resolution. For example, the scanning range of intelligent ultrasonic flaw detectors can reach 0~10000mm, the operating frequency is 0.4MHz~20MHz, and the resolution is greater than 40dB (5N14).
