概要分析了国内和油田建设中焊接技术现状,认为我国焊接机械化自动化和焊接辅助装置水平较低,常规手弧焊比例高,并使用普通焊条,生产效率低,难以完成大型容器的焊接任务。认为应重点引进自动、半自动焊机设备的辅助装置和双丝埋弧焊、预热焊丝埋弧焊等新工艺,扩大CO_2焊工艺,加强各类装备的维修力量和新工艺试验、推广。
The status quo of welding technology in domestic and oilfield construction is briefly analyzed. It is considered that the level of automation of welding mechanization and welding auxiliary equipment in our country is low, the proportion of conventional hand arc welding is high, and ordinary welding electrodes are used. The production efficiency is low and it is difficult to complete the welding task of large vessels. It should be emphasized that the introduction of automatic, semi-automatic welding machine auxiliary equipment and double-wire submerged arc welding, preheating wire submerged arc welding and other new technologies to expand CO_2 welding process, and strengthen the maintenance of various types of equipment and new technology test and promotion.
