Abstract

The invention discloses an electric-arc ultrasonic seam-welding composite welding device. The electric-arc ultrasonic seam-welding composite welding device comprises an ultrasonic device and an electric-arc welding device, wherein the ultrasonic device comprises an ultrasonic seam-welding machine and an arc welding rolling wheel, the arc welding rolling wheel is connected with an output shaft of the ultrasonic seam-welding machine, and the ultrasonic seam-welding machine converts an ultrasonic wave to vibration and transfers the vibration onto the arc welding rolling wheel; and the electric-arc welding device comprises an electric-arc welding gun, the electric-arc welding gun is fixed together with the ultrasonic seam-welding machine, and the arc welding rolling wheel generates vibration for a workpiece to be welded to refine grains in a welding area while the electric-arc welding gun welds the workpiece to be welded. In this way, the arc welding rolling wheel rotates on an arc welding guide rail to generate high-frequency vibration for the welding area and co-acts with the electric-arc welding gun clamped on the ultrasonic seam-welding machine to refine the grains in the welding area while the ultrasonic seam-welding machine and the arc welding rolling wheel move along a flexible guide rail, thus weld structure and mechanical properties are improved, and the welding effect is improved.

Description

technical field [0001] The invention relates to the fields of arc welding and arc smelting, in particular to an arc-ultrasonic roll welding composite welding device. Background technique [0002] Arc welding is the first welding method invented and used, and it is widely used in industrial production. In order to expand the application range of arc welding and further improve welding efficiency, many new arc welding methods have been invented and applied in industrial production, such as high-frequency pulsed argon arc welding, laser enhanced arc hybrid welding, double-sided arc welding and double tungsten electrode TIG et al. However, the above-mentioned method still has deficiencies at present, such as many auxiliary processes, low welding efficiency, high cost, and being difficult to apply to airtight containers. [0003] In view of the relative advantages of ultrasound, more and more scholars introduce ultrasonic vibration into welding, such as ultrasonic assisted weld...
