Test project introduction: Eddy current flaw detection testing is a non-destructive testing method used to detect surface or near-surface defects of conductors , such as cracks, inclusions, fatigue cracks, welding defects, etc. This test uses a high-frequency AC power supply, an eddy current probe and a signal processor to generate an alternating electromagnetic field, which generates eddy currents on the surface or near surface of the conductor to be inspected through induction. The changes in the eddy currents are related to the nature of the defect, and are passed through the inspection probe. The sensed signal changes determine the presence or absence of surface or near-surface defects on the conductor, as well as their size, shape, depth, and direction. This test method is suitable for the detection of conductive materials such as metal materials, composite materials, ceramics and plastics. In the industrial field, eddy current flaw detection testing is used in aviation, aerospace, nuclear power, petrochemical, shipbuilding, rail transit, automobile, machinery manufacturing and other industries.

What does the BAIJIAN test report do? What problems can it help you solve?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Research and development reports. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data.problems, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.
