  • ULTRASONIC-STIRRING NARROW GAP WELDING SYSTEM AND WELDING METHOD
    Publication number: 20250010392
    Abstract: An ultrasonic-stirring narrow gap welding system and a welding method, and the ultrasonic-stirring narrow gap welding system includes a welding machine power source, a wire feeder, a narrow gap welding torch, and an ultrasonic stirring subsystem. A welding wire is fed into a narrow gap through the narrow gap welding torch provided above a groove, to generate an arc for welding. The ultrasonic stirring subsystem includes a stirrer and an ultrasonic device, a stirring rod is connected to the ultrasonic device and inserted into a molten pool to form a preset angle relative to the welding wire for stirring, and an ultrasonic-stirring narrow gap welding mode is realized.
