In automatic welding machines, the technical problem of real-time detection and control of welding process quality is welding image processing technology. With the continuous improvement of the automation level of modern welding technology in my country, the key technology is the control of welding quality.
At present, various chemical and physical phenomena such as light, heat, electricity, sound, and magnetism existing in the welding process are detected through various sensing technologies such as temperature field measurement, optical sensing, acoustic sensing, and molten pool oscillation information. The quality of the welding process, because the welding process has the characteristics of high coupling, many parameters, and timely degradation, it is difficult to overcome the problem of missing welding in the automatic welding process.
With my country's accession to the WTO, automatic welding machines have met international standards. Industrial enterprises vigorously advocate "safety, health, and environmental protection" management, that is, HSE management. It is very urgent to improve the production environment for workers' field welding. For this reason, the domestic automatic welding machine factory has developed various types of pipeline all-position automatic welding machines, and has also introduced foreign automatic welding machines. With the acceleration of the construction of large-diameter pipelines in my country, the development of automatic welding equipment with more perfect performance is expected. Must do.
The application of image processing technology in the field of welding has attracted wide attention from scholars at home and abroad. Using this technology, by monitoring the position of the dynamic welding molten pool and the dynamic shape of the molten pool, the automatic welding process and its welding quality can be automated. Control; can also realize automatic non-destructive testing of welding defects.
The automatic welding machine analyzes the application characteristics and structure of automatic welding equipment at home and abroad, and points out the technical defects and improvement directions of this automatic welding equipment to promote the application of automatic welding technology in long-distance pipeline welding in my country. field. The self-developed automatic welding equipment has made technical improvements and innovations in mechanical mechanisms, electric actuators and control systems, and has cooperated with domestic arc welding power supply manufacturers to develop automatic welding equipment with excellent performance and low price. It will definitely be used in the petrochemical industry. It is widely used in the field of long-distance pipeline welding in water conservancy and power enterprises.
