Why Wuhan electric welding machine has not been tested in practice?

The reasons why the actual operation of Wuhan welder failed the test are as follows:

1. Examination arrangement: The welder's practical examination needs special examination place and equipment, and the examination place and time need to be arranged in advance. If the examination place and equipment cannot be arranged in time, the examination will never be conducted.

2. Shortage of personnel: The examination needs to have enough examiners and invigilators. If there are insufficient personnel or can't recruit suitable personnel in time, no examination will be conducted.

3. Industry adjustment: The welder's practical examination is affected by industry adjustment. If the relevant policies, standards or requirements change, it is necessary to re-formulate or adjust the examination.
