新型自行走式充氩装置的研究及应用

Research and Application of a New Self-Propelled Argon Filling Device

摘要: 氩弧焊技术被广泛应用于国内外的不锈钢管、合金管等管道的根部焊接。氩弧焊焊接时，一般采用管端封堵、整段管道内部充氩保护的方法来防止焊道氧化。此方法耗时长且无法保证焊接质量，对人工、材料成本造成巨大浪费。新型自行走式充氩装置成功利用机械自动化代替人力，不仅缩减氩弧焊充氩工艺流程，而且将管端封堵缩小为焊接区域局部封堵、增加内置摄像功能及装置自动行走功能，达到缩短焊接前准备时间、提高氩气利用率、实现焊道成型可视化、减少焊工数量的效果，对于工程项目提高功效、保证焊接质量、节省施工成本起到至关重要的作用。

Abstract: Argon-arc welding technology is widely used in root pass welding of stainless steel pipes, alloy pipes and other pipelines in the domestic and overseas. It is generally used to block the pipe end and fill the whole section of the pipe with argon to prevent welding path oxidation. This method takes a long time and cannot guarantee the welding quality, resulting in a huge waste of manpower and material costs. The new self-propelled argon filling device successfully used mechanical automation instead of human. It reduces argon arc welding argon filling process, shrinks tube end sealing for welding area local block device, and increases the built-in camera and automatic walking function, to shorten the preparation time before welding, improve the utilization rate of argon, realize the bead forming visualization, and reduce the number of welders. It plays a vital role in improving the efficiency of the project, ensuring the welding quality and saving the construction cost.
