There are three kinds of welder training institutions, local junior workers and intermediate workers are very common, and they are from the Safety Supervision Bureau. The training of welders by 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. This requirement is high, so the training is more difficult and the salary is higher. Senior welder training or high-pressure welder training is enough.

Common sense of welders:

1, common welding methods (fusion welding; Pressure welding and brazing).

2. Manual arc welding, gas welding and gas cutting, argon arc welding and co2 gas shielded welding.

3. Selection and storage of covered electrode types, types and use of welding equipment and forms of welding joints.

4, the formation principle of weld.

5. Selection of welding position (horizontal welding, vertical welding, horizontal welding and overhead welding) and welding process parameters (welding current, arc voltage, welding polarity, welding speed, etc.). ), weld layout and weldment structure, gas welding technology and cutting technology, gas welding and gas cutting of common metal materials, argon arc welding principle, equipment use and welding technology.

6, welding deformation and stress and its generation and prevention methods.
