Whether or not the person in charge of each quality control system can concurrently hold the post in the licensing conditions of Class D pressure vessels, and which ones can concurrently hold the post

Whether or not the person in charge of each quality control system can concurrently hold the post in the licensing conditions of Class D pressure vessels, and which ones can concurrently hold the post, and a person in charge can concurrently hold several posts at most. 1) The quality assurance engineer shall not hold other positions concurrently.

Only when the person in that position leaves his post temporarily can the quality assurance engineer supervise his post in a short time, such as signing his name. But in the long run, this position still needs to be recruited.

2) Other quality control system personnel can hold concurrent positions, generally speaking, each person has at most two. For example, welding responsibility heat can be responsible for heat treatment, design and technology, physics and chemistry, measurement and so on.

Hehe, I have learned all the following answers. Look at Article 4 of TSG Z0004-2007 "Basic Requirements for Quality Assurance System for Manufacture, Installation, Modification and Maintenance of Special Equipment" and learn and understand it.
