Welding: With the development of China's economy, welding technology has become an indispensable processing method in many industrial fields, including automobile, aviation, aerospace, nuclear industry, shipbuilding, construction and machinery manufacturing. However, at present, the training of welding professionals in China can not meet the needs of social employment. In particular, there is a shortage of welding technical personnel such as bidirectional welding, argon arc welding and manual arc welding, which makes the demand for welding technical personnel large, urgent and high-paid.

2, auto repair technology: easy to learn and understand, even if it is zero-based. Many students started from scratch and gradually emerged through study. In addition, learning automobile beauty, quick repair and quick maintenance can make you have the ability to open a shop, and the relatively low technical threshold and investment also mean that you will have more chances of success.
