1. The greater the applied external magnetic field strength, the greater the induced magnetic field strength in the workpiece, the denser the distribution of magnetic lines, and the greater the strength and quantity of magnetic line bending obstructed by defects, resulting in an increase in the strength of the leakage magnetic field formed.

In the process of automated production of industrial equipment, it is necessary to judge the quality of products. Traditional manual visual judgment has low efficiency, and the accuracy of quality judgment is often affected by visual ghosting and lighting issues during the judgment process

The Keysight i7090 online testing system has the capabilities of ICT, power on, programming, and functional testing. It supports 20 cores for simultaneous testing, 160 programming channels for simultaneous programming of the tested product, and 16 sets of programmable power supplies. It also supports Keysight or third-party PXI interface instruments for functional testing,

Users who are using the flaw detector for the first time may not be familiar with the settings and selection of the instrument's straight probe and oblique probe. Here is a brief introduction to the differences in probe settings for users: 1. Straight probe: 1 Instrument settings: (1) Basic main menu ① Limitations: Determine based on the thickness of the workpiece ② Sound velocity is 5920 meters per second (2) Angle probe main menu ① Probe angle is "0"

AXI (Automated X-Ray Inspection) is a type of optical inspection system used for automated X-ray testing. AXI is a relatively mature testing technology. After the assembled circuit board (PCBA) enters the machine along the guide rail, there is an X-Ray emitter tube located above the PCB,

Today, the editor will talk to you about what to pay attention to when charging a flaw detector? 1. Please make sure to use a dedicated power adapter to charge the battery. If using a non local charger to charge the flaw detector causes problems, it is not covered by the warranty.

As soon as you hear the name "flaw detector", you will know that it detects objects through a type of sound wave. As for what it detects, many people may not be familiar with it. Since ultrasonic waves are used for measurement, it is inevitable that other factors may cause inaccurate measurement values,

The flaw detector is mainly used to detect whether there are defects (cracks, sand holes, pores, white spots, inclusions, etc.) inside the machined parts, whether the welds are qualified, and to search for hidden injuries, in order to determine whether the workpiece is qualified or not. Flaw detectors are generally used for non-destructive testing. Industrial sectors such as shipbuilding, petroleum, chemical, mechanical, aerospace, transportation, and construction inspect materials such as ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles, and bridges

Nowadays, flaw detectors usually emit ultrasound to the object being tested (such as industrial materials, human body), and then use its reflection, Doppler effect, transmission, etc. to obtain information inside the object and process it to form an image.
