Is utmt mining machine legal

1. Mining skills of light of hope in the story of Ranch
here I'd like to share with you the tips I found in the first 30 layers. At present, my hammer has not been upgraded. I don't know if it's useful in the back of the 31 layers
don't rush to smash the ore when you go down the mine. The probability of getting out of the stairs is very low around the stairs + ore. if you dig around the stairs, if you don't have good luck, you will dig around the ore
it takes at least 2 hours to enter the mine. If you don't stay in the mine for 2 hours, you will lose time when you come out.

1. UT: ultrasonic test ultrasonic flaw detection is a method to check the defects of parts by using the characteristics of reflection at the interface edge when the ultrasonic energy penetrates into the depth of metal materials and enters into another section from one section. When the ultrasonic beam passes from the probe head to the metal from the surface of parts, the reflection wave will occur respectively when it meets the defects and the bottom of parts, The position and size of the defect can be judged according to the pulse waveform formed on the screen

these methods are different detection means, which should be studied separately. They have different theoretical basis, different detection principles, different detection methods, and different detection effect, which are complementary to each other

RT: radiographic inspection

ut: ultrasonic inspection

MT: magnetic particle inspection belongs to non-destructive inspection

4. What are UT and MT in NDT? UT: ultra sonic test
MT: magnetic test
magnetic particle inspection has another name: MPI, that is,
magnetic particle inspection
in addition, NDT is non destructive testing in English. Non destructive testing refers to the physical or chemical methods, with the help of modern technology and equipment, to analyze the internal and surface structure, properties and mechanical properties of the test piece by using the changes of thermal, acoustic, optical, electrical, magnetic and other reactions caused by the abnormal internal structure or defects of the material, on the premise of not damaging or affecting the service performance of the tested object and the internal organization of the tested object State and defect type, nature, quantity, shape, location, size, distribution and change of inspection and testing method [1]. Nondestructive testing is an indispensable and effective tool for instrial development. To a certain extent, it reflects the instrial development level of a country. The importance of nondestructive testing has been recognized, including radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT) and liquid penetrant testing (PT). Other nondestructive testing methods include eddy current testing (ECT), acoustic emission testing (AE), thermal imaging / infrared (TIR), leakage test (LT), AC field measurement technology (acfmt), magnetic flux leakage testing (MFL), far field testing (RFT), ultrasonic time difference of diffraction (TOFD), etc.

5. UT is ultrasonic testing and MT is magnetic particle testing. UT uses ultrasonic testing to detect the internal defects of metal through reflected wave, and MT uses magnetic powder to detect the surface defects of metal through magnetic pole. Level 2 qualification is the qualification that can be tested.

6. Generally speaking, the first level examination is relatively simple. You can basically pass the theory if you look at the teaching materials; Theory is generally single choice, multiple choice, judgment can account for about 60 points, discussion question 20 points, general 5 to calculation question 2 10 points, practice is to give you instrument or material, make test results on standard test block or test board, for MT PT test results require accuracy is not very high, make defects, and then issue test records and reports, RT practice is also relatively simple, The first one is to look at the negatives first. You have to look at at at least 1000 negatives in order to have a more intuitive impression. Otherwise, you will be directly blinded ring the exam. Everything is defective. When you pass through the negatives, you should select the time according to the exposure curve. Generally, you need to add 5-10 seconds to this time, because the exam optics are relatively old, His energy is weakened. When developing the film, you only need to shake three times, so adding some time can at least ensure that the blackness meets the requirements. Ultrasonic practice is the most difficult, because you first have to understand the principle of ultrasonic and familiar with the instrument, and then you can make the test curve according to the standard, issue the record and report. In half an hour, you really have to do more, practice more, and the rest has no solution.

7. Of course, it's reliable. Jiajia supply chain is quite good. Many of our foreign trade partners in Langfang cooperate with this enterprise. It's reliable and can save money

8. If it's a long weld, it's charged by meter, if it's a small one, it's also charged by centimeter. It's more suitable for a large package.

if you see the supplement of 30, it's the lowest per meter. The key is whether the other party should report it or not

9. It must be attached. The testing unit can use it. If it is attached, the four second level certificates are not very valuable. It depends on the company you are looking for. If it is not attached, the certificate will be invalid

nondestructive testing is no longer just using X-ray, including acoustic, electrical, magnetic, electromagnetic wave, neutron, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave, electromagnetic wave Laser and other physical phenomena are almost used in nondestructive testing

for example: ultrasonic testing, eddy current testing, magnetic particle testing, radiographic testing, penetrant testing, visual testing, infrared testing, microwave testing, leakage testing, acoustic emission testing, magnetic flux leakage testing, magnetic memory testing, thermal neutron photographic testing, laser speckle imaging testing, fiber Bragg grating sensing technology, etc., and new methods and technologies are constantly developed and applied

in fact, many new technologies have been developed for some seemingly very traditional nondestructive testing methods, such as:

(1) radiographic testing - the traditional technology is film radiography (X-ray and gamma ray). New technologies include accelerator high energy X-ray radiography, digital radiography (DR), computer radiography (Cr, similar to digital radiography), computer tomography (CT), X-ray diffraction, etc

(2) ultrasonic testing: the traditional technology is A-mode ultrasound (A-scan ultrasound, a-ultrasound). New technologies include: B-scan ultrasound (B-ultrasound), C-scan ultrasound (c-ultrasound), ultrasonic diffraction (TOFD), phased array ultrasound, resonance ultrasound, electromagnetic ultrasound, ultrasonic guided wave, etc
