With the development of electronic technology, computer technology, numerical control and robot technology, automatic welding robots have been used in production since the 1960s. Their technology has become increasingly mature and has the following advantages:
1) Stabilize and improve welding quality, and reflect welding quality in numerical form;
2) Improve labor productivity;
3) Improve workers' labor intensity and work in harmful environments;
4) Reduce the requirements for workers' operating skills;
5) Shorten the preparation period for product modification and replacement, and reduce the corresponding equipment investment.
Therefore, it has been widely used in various industries.
