In industrial enterprises, we are vigorously advocating "health, safety and environmental protection" management, that is, HSE management. It is very urgent to improve the production environment of workers' field welding. Therefore, domestic welding equipment manufacturers have developed various forms of pipeline all position automatic welding machines, and also introduced foreign full-automatic welding machines.

隨著我國大口徑管道建設的加快，研制性能更加完善的自動焊接設備勢在必行。通過分析國內外自動焊接設備的結構和應用特點，指出這類自動焊接設備在技術上存在的不足和改進方向，以促進自動焊接技術在野外長輸管道焊接中的使用。

With the acceleration of large-diameter pipeline construction in China, it is imperative to develop more perfect automatic welding equipment. By analyzing the structure and application characteristics of automatic welding equipment at home and abroad, this paper points out the technical shortcomings and improvement direction of this kind of automatic welding equipment, so as to promote the application of automatic welding technology in field long-distance pipeline welding.

國內開發自動焊接設備從機械機構，電氣執行元件，控制系統方面進行技術改進和創新，并和國內弧焊電源生產廠家協作，開發出性能優良，便宜的自動焊接設備，必將在石油化工，水利電力企業的野外長輸管道焊接中得到廣泛的使用。

The domestic development of automatic welding equipment carries out technical improvement and innovation from the aspects of mechanical mechanism, electrical actuator and control system, and cooperates with domestic arc welding power manufacturers to develop automatic welding equipment with excellent performance and low price, which will be widely used in the field long-distance pipeline welding of petrochemical, water conservancy and electric power enterprises.
