Welder training institutions are divided into three categories, namely, local junior workers, intermediate workers and safety supervision bureaus. The welder training of the Safety Supervision Bureau is mainly the introduction of safety knowledge, and the other is the high-voltage welder certificate of the Quality Supervision Bureau, which requires higher requirements, so the training is more difficult and the salary is higher. Senior welder training or high-pressure welder training is enough.

You can go to the training school to make a field trip and choose.
