PLASMA TAPHOLE WELDING OF HARDENABLE STEEL

摘要

The invention relates to a method for producing a weld seam (1) in hardenable steel (2) with a material thickness (3) without having to resort to secondary heating, comprising at least the following steps: a) positioning of a welding electrode (4) on a welding line (5); b) applying a voltage; c) supplying a plasma gas (6); d) forming an electric arc (7); and e) melting the steel (2) in the vicinity of the welding line (5) over the entire material thickness (3). In a preferred application, the inventive method is used for connecting components for transmitting torque in motor vehicles.
