A friend who wants to join a welder reminds me that if you want to be a welder, you can't do it without a welder's license! According to the relevant national regulations, welders must undergo safety operation training and obtain welder's operation certificate before they can work at their posts!

Note: Article 27 of the Law of People's Republic of China (PRC) on Safety in Production: Special operators of production and business units must receive special safety operation training in accordance with relevant state regulations and obtain corresponding qualifications before taking up their posts. Special operations personnel must hold relevant certificates. It is recommended to go to a professional college for training.
