(1) The intellectualization of welding process control system is one of the core problems of welding automation, and it is also an important research direction in the future. The research of control methods should be carried out, including linear and various nonlinear control. The representative is the research of fuzzy control, neural network control and expert system of welding process.

（2）焊 接柔性化技術也是著力研究的內容。在未來的研究中，將各種光、機、電技術與焊 接技術有機結合，以實現焊 接的精 確化和柔性化。用微電子技術改造傳統焊 接工藝裝備，是提高焊 接自動化水平淡的根本途徑。將數控技術配以各類焊 接機械設備，以提高其柔性化水平，是當前的一個研究方向；另外，焊 接機器人與系統的結合，實現自動路徑規劃、自動校正軌跡、自動控制熔深等功能是研究的。

(2) Welding flexibility technology is also the focus of research. In the future research, all kinds of optical, mechanical, electrical technology and welding technology will be organically combined to realize the accuracy and flexibility of welding. The fundamental way to improve the level of welding automation is to transform the traditional welding process equipment with microelectronic technology. It is a current research direction to match NC technology with all kinds of welding machinery and equipment to improve its flexibility level; In addition, the combination of welding robot and expert system to realize automatic path planning, automatic trajectory correction and automatic control of penetration is the focus of the research.

（3）焊 接控制系統的集成是人與技術的集成和焊 接技術與信息技術的集成。集成系統中信息流和物質流是其重要的組成部分，促進其有機地結合，可大大降低信息量和實時控制的要求。注意發揮人在控制和臨機處理的響應和判斷能力，建立人機圣誕的友好界面，使人和自動系統和諧統一，是集成系統的不可低估的因素。

(3) The integration of welding control system is the integration of human and technology, and the integration of welding technology and information technology. In the integrated system, information flow and material flow are the important parts, which can greatly reduce the amount of information and the requirements of real-time control. Pay attention to give full play to the response and judgment ability of human in control and on-the-spot processing, establish a friendly interface between human and computer, and make human and automatic system harmonious and unified, which is an important factor of integrated system.

（4）提高焊 接電源的可靠性、質量穩定性和控制，以及優良的動感性，也是著重研究的課題。開發研制具有調節電弧運動、送絲和焊槍姿態，能探測焊縫坡開頭、溫度場、熔池狀態、熔透情況，適時提供焊 接規范參數的高性能焊機，并應積極開發焊 接過程的計算機模擬技術。使焊 接技術由“技藝”向“科學”演變輥實現焊 接自動化的一個重要方面

(4) To improve the reliability, quality stability and control of welding power source, as well as the excellent mobility, is also the focus of research. To develop a high performance welding machine which can adjust the arc movement, wire feeding and welding torch posture, detect the start of weld slope, temperature field, molten pool state and penetration, and timely provide welding specification parameters, and actively develop the computer simulation technology of welding process. It is an important aspect of welding automation to make welding technology evolve from "skill" to "science"
