摘要： A method for automated circumferential welding of a workpiece by means of at least one welding device, including: (a) determining a further weld path for a further weld to be welded on the workpiece, the further weld extending from a start point, via a downstream part to a stop point, (b) determining first welding parameters associated with the further weld and adapted to weld the further weld on the workpiece, the first welding parameters are adapted to transfer a first level of heat to the workpiece, (c) identifying at least one overlap area in the further weld path between the downstream part and the start point of the further weld or between the further weld and a start or stop point of a previous weld, (d) determining a boost area, the boost area including the at least one overlap area, (e) determining boost welding parameters associated with the boost area and adapted to weld the further weld in the boost area, the boost welding parameters are adapted to transfer a second level of heat to the workpiece, the second level of heat exceeding the first level of heat, and (f) welding the further weld from the start point to the stop point thereof, the first welding parameters are selected for welding of the further weld outside the boost area, and the boost welding parameters are selected for welding the further weld inside the boost area.
