With the increasing maturity of digital technology, digital welding machines and digital control technologies, representing advanced welding technology, have steadily entered the market. Large-scale national infrastructure projects such as the Three Gorges Project, the West-East Gas Pipeline Project, aerospace engineering, and shipbuilding engineering have effectively promoted the development and progress of advanced welding, especially welding automation technology. The manufacturing of automobiles and auto parts demands ever-increasing levels of automation in welding. my country's welding industry is gradually moving towards "high efficiency, automation, and intelligence." However, my country's welding automation rate is still less than 30%, far behind the 80% of developed industrial countries. Since the late 20th century, the country has gradually promoted gas shielded welding-the basic welding method for automatic welding-in various industries to replace traditional manual arc welding, and initial results have been achieved. It can be predicted that in the future, domestic automated welding technology will develop at an unprecedented speed.
The development of electronic technology, computer microelectronics, and automation technology has driven the development of welding automation technology. In particular, the introduction of unit technologies such as CNC technology, flexible manufacturing technology, and information processing technology has promoted a revolutionary development in welding automation technology.
