| 摘要 |
The invention relates to a welding device (1) and a method for welding workpieces (2, 3), using a rotating, magnetically driven electric arc (4). The welding device (1) comprises a feed device (11) for a workpiece (2, 3), a current source (12) and a drive device (10) for the electric arc (4). The welding device (1) further comprises an additional heating device (13) for heating the connected workpieces (2, 3) in the joining region (5). The heating device (13) is designed as an additional current source (14) which can be electrically conductively connected to the workpieces (2, 3), wherein the workpieces (2, 3) are in addition conductively heated by an electric current flow. |
