Does Tieling Safety Supervision Bureau give welder certificate negative audit?

The welder's certificate that needs annual inspection is the welder's operation certificate, and the operation certificate issued by the safety supervision bureau is universal and nationwide, and all local safety supervision bureaus can conduct annual inspection.

After the welder's certificate expires, it will be assessed in the local safety production supervision bureau. The welder's special post operation certificate will be issued by the safety supervision bureau and can be used anywhere. It used to be called card reading, but now it's called proximity card, and it takes an exam every three years. Just like the ID card, as long as there is a special card reader.
