The development of electronic technology, computer microelectronics residence and automation technology has promoted the development of welding automation technology. In particular, numerical control technology, flexible manufacturing technology and information processing technology, such as the introduction of unit technology, has promoted the revolutionary development of welding automation technology.
(1) The Intelligent Welding Process Control system is one of the core problems of welding automation, and also the important direction of our future research. We should conduct research on optimal control methods, including linear and various nonlinear controls. The most representative is the fuzzy control of welding process, neural network control, and the study of expert system.
(2) The technology of welding flexibility is also the content that we focus on. In the future research, we combine all kinds of light, machine, electric technology and welding technology organically to realize the precision and flexibility of welding. It is the basic way to improve the level of welding automation to transform the traditional welding equipment with microelectronics technology. It is our current research direction to combine numerical control technology with all kinds of welding machinery and equipment to improve its flexible level. In addition, the combination of welding robot and expert system realizes automatic path planning, automatic correction trajectory and automatic control of molten depth.
(3) The integration of welding control system is the integration of human and technology, welding technology and information technology. The information flow and material flow in the integrated system is an important part of it, which promotes its organic combination, which can greatly reduce the requirement of information and real-time control. Pay attention to the ability of people in the control and the handling of the PAA response and judgment, the establishment of human-machine Christmas friendly interface, so that people and automatic system harmony and unity, is an integrated system can not be underestimated factors.
(4) Improve the reliability of welding power supply, quality stability and control, as well as excellent dynamic, is also our focus on research topics. The development of a high performance welder with adjustable arc movement, wire feeding and welding torch, which can detect the opening of weld slope, temperature field, molten pool state and penetration condition, and provide the welding specification parameters in time, and should actively develop computer simulation technology of welding process. Make welding technology from "technology" to "scientific" evolution roller to achieve an important aspect of welding automation. The first ten years of this century will be a favorable period for the rapid development of welding industry. The vast majority of our welding workers to be a long way, it is necessary to establish a knowledge of the difficult and determined. Seize the opportunity for China's welding automation level and strive to improve.
