概述了国内外学者对于十种熔焊焊接技术立焊工艺的研究现状,分析了各种立焊工艺的优缺点。主要包括手工焊条电弧焊立焊、变极性等离子弧穿孔立焊、半自动CO2气体保护焊立焊、激光立焊、向下立焊、双人同步TIG立焊、电渣焊立焊、自动CO2气体保护焊立焊、气电立焊、自熔导管自保护药芯焊丝式立焊等。评述了手工自蔓延焊接技术及其所具有的军事及民用价值,并着重讨论了手工自蔓延焊接的立焊工艺所存在的问题,指出了需要进一步深入研究攻关的方向。
Summarizes the domestic and foreign scholars for the ten kinds of welding technology of vertical welding technology research status, analysis of the advantages and disadvantages of various vertical welding process. Including manual welding arc welding legislation, variable polarity plasma arc perforated vertical welding, semi-automatic CO2 gas shielded welding, laser vertical welding, vertical welding, simultaneous dual TIG welding, welding welding, welding, automatic CO2 gas Welding protection welding, gas vertical welding, self-protection of self-fluxing cored wire welding and so on. The manual self-propagating welding technology and its military and civilian value are reviewed. The problems existing in the vertical welding process of manual self-propagating welding are also discussed, and the direction of tackling the problem is pointed out.
