  "abstract": "The present invention provides a fixture and method for improving the performance of electromagnetic pulse welding joints. The fixture comprises a base and a pressing block. In the present invention, the pressing block and the base are closely attached to each other through the cooperation of a semi-through groove and a protrusion, and the pressing block is compacted by a pressing plate, so that the semi-through groove is sealed. The semi-through groove may be filled with a specific atmosphere through a suction hole and a gas conveying hole, so that welding may be completed under different atmospheres. By selecting the type of atmosphere, the resistance of a flyer plate and the associated energy loss caused by high-speed movement of the workpieces to be welded can be effectively reduced, so that the welding quality is ensured.",
