Abstract�� Double-sided arc welding (DSAW) is a new technology which has been utilized in recent years. It 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.
Keywords�� electrical arc   weld penetration   electromagnetic fields
