变极性等离子弧自动焊接技术在大型密封结构焊接中的应用
Application of variable polarity plasma arc welding technology for large-scale sealing structures
摘要
Abstract
The technique of variable polarity plasma arc welding(VPPAW) is analyzed in terms of its development history. The application of VPPAW for materials and structures of China's new type large-size spacecraft is discussed with special emphasis on the engineering challenges, and then the countermeasures are proposed. Studies and tests show that VPPAW is one of the best processing schemes for the welding of medium-thick aluminum alloy structures. The application prospects of this technique are evaluated.关键词
