摘要
双面电弧焊接DSAW(Double SidedArcWelding)是近年来出现的一种焊接新工艺 ,它可以有效地增大焊缝熔深、减少焊接缺陷、降低焊接变形、提高焊接速度、节约能源消耗 .从实际应用角度 ,介绍了DSAW工艺的基本形式 ,讨论了单电源及双电源情况下的工艺原理 ,重点对单电源DSAW工艺增大熔深的机理进行了分析 ,从电弧物理角度揭示了双面电弧的焊接机理 。
Double-sided arc welding (DSAW) is a technology which has many advantages such as increasing weld penetration, decreasing weld defects, reducing welding deformation, improving welding speed and saving power consumption. The basic types and technological mechanism of DSAW process were introduced. The mechanism of increasing joint penetration in single-power DSAW process was discussed. The welding mechanism of DSAW was revealed from arc physics side. The practical use of DSAW process would be improved.
