I want to learn nondestructive testing. Do you want to learn? How high is the salary? People of insight, please advise.

Non-destructive testing is a professional technical activity, and the simple basic operation and cultural level are not very good. The first-class flaw detection certificate is relatively easy to obtain. However, if you want to get the second and third-class certificates, you need to have solid skills and a certain theoretical level. Especially level three. Wages are uneven. But because it is a technical job, junior workers in medium-sized cities can also get more than 2 thousand to 3 thousand. Of course, the older you get, the more popular you are. A third-level master can earn 10 thousand a month. Of course, what I say is not necessarily absolute, but also depends on your company. Generally speaking, there is a shortage of flaw detection personnel, employment is not a problem, and the treatment is improving year by year. I hope to adopt.
