In recent years, with the rapid development of industrial robots, more and more automobile manufacturers have begun to introduce robot automatic welding machine to improve the automation degree and welding quality of welding operation.

[0003] However, the current widely used automobile pipeline welding robot automatic welding machine on the market still has some significant technical limitations.
