摘　　要：A three dimensional current density distribution in double-sided gas tungsten arc welding (GTAW) proces is performed. The current density distribution field is evaluated by numerically solving Maxwell equations in the domain of the workpiece. In the boundary condition, the current density on. the workpiece surface is assumed as Gaussian distribution. Results show that the current distribution in DSAW is different from single side arc welding, it is more concentrated and the relative location of the two torches influence the current distribution greatly. 关键词：
