In Chengdu, where the welder certificate is tested, the detailed process.

I don't know the details. Try to tell me what I know: 1. If you cooperate with the company, the company should cooperate with the owner to organize the examination. Last time the steel truss of Shuangliu Airport was welded, the employer asked for an examination, and he took it on the spot and took up his post after the examination. 2. The examination is organized by qualified schools. Deyang, I know Southwest Engineering School can take the exam.
