What is the job like as a damage detector?

Flaw detection is a technical job, and what matters more is experience. Flaw detection is actually a common name, and the scientific name should be called non-destructive testing, or non-destructive testing for short.

The principle of non-destructive testing is a bit like the B-ultrasound in the hospital, except that one is looking at children and the other is looking at steel or various alloys. Use X-rays to penetrate the steel to check whether the welding seam meets the standard during the manual welding process. If it is a pressure vessel classified into categories (Class I, Class II, or Class III), the requirements for the welding seam are quite high, so The requirements for non-destructive testing are also very high. After the ray passes through the steel, a film will be taken to observe whether there are bubbles or abnormalities caused by slag inclusions during the welding process (this requires the teaching of the master and long-term experience accumulation). If it exists, You can ask the welder to rework. By the way, the state has very strict control over pressure vessels. Therefore, if you want to work in this industry, you must cultivate a meticulous work attitude. Otherwise, if nothing happens, it will be a matter of life and death.

Engaging in non-destructive testing is actually risky. You must use the testing equipment strictly in accordance with the operating requirements and keep a distance from the ray machine when using it. It is said that rays kill a chromosome in sperm. People still lose their hair after the age of 40. Haha, young man, those who are not married and have children should be more careful. However, several people I know who work in flaw detection still gave birth to fat boys. Including my dad, haha. In fact, there is nothing dangerous if you pay attention.

As for development, there are actually not many people engaged in this job, but it is very necessary, and the wages are also good. If you are in a state-owned enterprise, one year of service is equivalent to one and a half years. The conditions are favorable, that is to say, if you work for 20 years, it is equivalent to someone else working for 30 years. The work is not tiring at all, just do it if you want. You are absolutely guaranteed to have food even in wartime.
