Prospect of welding automation technology
Jul 30, 2018

The development of electronic technology, computer microelectronics residence and automation technology has promoted the development of welding automation technology. In particular, the introduction of unit technologies such as numerical control technology, flexible manufacturing technology and information processing technology has promoted the revolutionary development of welding automation technology.

(1) The intelligentization of the welding process control system is one of the core issues of welding automation, and it is also an important direction for our future research. We should conduct research on the best control methods, including linearity and various nonlinear controls. The most representative are the fuzzy control of the welding process, neural network control, and the study of expert systems.

(2) Welding flexibility technology is also the content of our research. In future research, we combine various light, machine and electric technologies with welding technology to achieve precision and flexibility of welding. Renovating traditional welding process equipment with microelectronics technology is the fundamental way to improve the level of welding automation. It is our current research direction to equip CNC technology with various welding machinery and equipment to improve its flexibility level. In addition, the combination of welding robot and expert system realizes automatic path planning, automatic correction of trajectory, automatic control of penetration, etc. Function is the focus of our research.

(3) The integration of welding control system is the integration of human and technology and the integration of welding technology and information technology. The flow of information and material flow in the integrated system is an important part of it, promoting its organic integration, which can greatly reduce the amount of information and real-time control requirements. Pay attention to the ability of people to respond and judge in control and process, establish a friendly interface for human-computer Christmas, and make people and automatic systems harmonious and unified, which is an inestimable factor of integrated systems.

(4) Improving the reliability, quality stability and control of the welding power source, as well as excellent dynamics, is also a topic we focus on. Developed a high-performance welder with adjustable arc motion, wire feeding and torch attitude, capable of detecting the beginning of the weld slope, temperature field, molten pool state, penetration, timely provision of welding specification parameters, and actively developing the welding process Analog technology. An important aspect of welding automation from the "art" to the "scientific" evolution of welding technology. The first decade of this century will be a favorable period for the rapid development of the welding industry. Our vast number of welding workers have a long way to go, and we must establish our determination to make it difficult. Seize the opportunity and work hard for the improvement of China's welding automation level.
