As a high-tech with good development prospects, welding robot technology integrates various technologies such as welding technology, electronic technology, mechanical technology, sensor technology, and has the title of "tailor" in modern industry.

After more than 50 years of development, welding robot technology has integrated multidisciplinary technologies such as information technology, sensor technology, and artificial intelligence to achieve intelligent and automated development. Currently, the digital arc welding power source used by welding robots has the advantages of fast response, good welding quality, strong repeatability, and stable output. However, at this stage, most of the arc welding power sources used are produced abroad. Although there are also products introduced in China, they still cannot achieve the desired level of control accuracy and welding stability. In terms of robot sensing, welding robots can use sensors in various disciplines such as electromagnetism, acoustics, and optics to achieve information extraction in the welding process and meet the automatic operation requirements of robot welding operations. Using multi-sensor information fusion technology can achieve the detection of weld deviation, spot welding quality, and other content, providing technical support for the implementation of intelligent welding operations. With the support of this technology, using a welding professional system as an adaptive unit and making welding decisions through fuzzy computation and neural networks can enable welding robots to achieve weld formation quality control. However, at present, this technology is still in the research stage, limited by the coordinated control problems of various systems. In terms of the welding production situation of welding robots, it is necessary to use teaching programming to achieve robot programming control, which is not conducive to the extension of the robot's workspace. However, in foreign countries, mature offline programming systems have been developed, while in China, the core technology is still in the hands of university science and technology personnel, still in the simulation stage.

From the perspective of the application of welding robot technology, the domestic market can be divided into three categories: domestic, Japanese, and European welding robots, including Panasonic, ABB, IGM, and other brands. The overall market share accounts for about 70% of the domestic market share. While domestic welding robots have gradually completed some brand building, their overall share is small, only about 30%. Due to the limitations of technological level, the core components of domestic welding robots mainly rely on imports, resulting in high prices for robots, limiting the development and expansion of the domestic welding robot market. From the perspective of application fields, welding robots have been applied in fields such as automobiles, construction machinery, and ships. In the field of domestic automobile manufacturing, welding robots are widely used, which can be used for arc welding and spot welding on automobile braking production lines, as well as processing and manufacturing parts such as vehicle bodies, automobile parts, and chassis, promoting the transformation and development of the domestic automobile industry from labor intensive to technology intensive. In the field of construction machinery, welding robots have also been applied, such as welding and manufacturing large-scale construction machinery and equipment such as bulldozers and excavators, with obvious application advantages. In the field of shipbuilding, welding robots are mainly used in Japan, the United States, and other countries. Due to the complexity of shipbuilding welding robot system technology, although welding robots have been applied in China, they mainly rely on the introduction of robot technology from abroad, which to some extent limits the development of domestic ship welding robot technology. In addition, welding robots have also been used to varying degrees in the fields of bicycles, locomotives, electrical, and aerospace, but overall, they have not been widely used in China.

Based on the development status of welding robot technology, it can be found that compared with foreign countries, the development of welding robot technology in China is still relatively backward. Therefore, in order to promote the transformation and development of "Made in China in the new century", it is necessary to strengthen the research on welding robot technology. Therefore, in the future development, China should also strengthen research on various issues existing in welding robot technology, such as seam tracking technology issues, multi robot coordination control issues, robot programming issues, and other advanced technical theories such as artificial intelligence, bionics, and cybernetics, to overcome technical difficulties, and strive to stay at the forefront of this field.

In the application of welding robot technology, in order to become a manufacturing power, China should also introduce welding robots into various fields of production and manufacturing as soon as possible to meet the development needs of national productivity. Currently, in addition to manufacturing, automation has also been developed in industries such as construction, agriculture and forestry, marine development, medical treatment, and services, which can provide greater development space for the application of welding robots. In combination with this development situation, it is also necessary to strengthen the research, development and manufacturing of special welding robots, and complete the research and development of special welding robots that can meet the needs of various fields, such as deep-sea welding robots, military welding robots, and construction welding robots, so as to continuously expand the application and development space of welding robots and effectively promote the development of welding robot technology.
