Future prospect of fiber laser welding machine technology.
The development of electronic technology, computer microelectronic accommodation and automation technology has promoted the development of automation technology of fiber laser welding machine.Especially, the introduction of numerical control technology, flexible manufacturing technology and information processing technology has promoted the revolutionary development of fiber laser welding machine automation technology.
(1) Intelligent welding process control system is one of the core issues of welding automation, and it is also an important direction of our future research.We should carry out research on the best control methods, including linear and various nonlinear controls.The most representative ones are fuzzy control, neural network control and expert system of welding process.
(2) Flexible welding technology is also the content we focus on.In the future research, we will combine all kinds of optical, mechanical and electrical technology with welding technology organically to realize the precision and flexibility of welding.It is a fundamental way to improve the level of welding automation to transform the traditional welding technology and equipment with microelectronic technology.It is one of our current research directions to combine numerical control technology with various kinds of welding machinery and equipment to improve its flexibility level.In addition, the combination of welding robot and expert system, to achieve automatic path planning, automatic track correction, automatic control of penetration depth and other functions, 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 information flow and material flow are the important components of the integrated system, and the integration of the information flow and material flow can greatly reduce the requirement of real-time control.Pay attention to play the human response and judgment ability in the control and emergency processing, establish a friendly interface between man and machine Christmas, make the human and automatic system harmony and unity, is the integrated system can not be underestimated factors.
(4) To improve the reliability, quality stability and control of welding power supply, as well as excellent motion, is also our focus on the research topic.Develop a high performance welding machine which can adjust arc motion, wire feed and welding torch attitude, detect the beginning of weld slope, temperature field, molten pool state and penetration, and provide welding specification parameters in time, and actively develop computer simulation technology of welding process.Make the welding technology from “technique” to “science” evolution roll to realize an important aspect of welding automation.The first decade of this century will be a favorable period for rapid development of welding industry.We welding workers have a long way to go and must set up the determination of knowing the difficulties.Seize the opportunity and strive to improve the level of welding automation in our country.
