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 接控制系统的集成是人与技术的集成和焊 接技术与信息技术的集成。集成系统中信息流和物质流是其重要的组成部分，促进其有机地结合，可大大降低信息量和实时控制的要求。注意发挥人在控制和临机处理的响应和判断能力，建立人机圣诞的友好界面，使人和自动系统和谐统一，是集成系统的不可低估的因素。

(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 接电源的可靠性、质量稳定性和控制，以及优良的动感性，也是着重研究的课题。开发研制具有调节电弧运动、送丝和焊枪姿态，能探测焊缝坡开头、温度场、熔池状态、熔透情况，适时提供焊 接规范参数的高性能焊机，并应积极开发焊 接过程的计算机模拟技术。使焊 接技术由“技艺”向“科学”演变辊实现焊 接自动化的一个重要方面

(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"
