Abstract

The invention discloses a novel pulse ultrasonic electric arc hybrid welding device and a welding method thereof, and belongs to the technical field of electric arc welding and welding metallurgy. Theproblems that an existing pulse ultrasonic field is unstable in output, poor in heat dissipation of an energy converter, incapable of working for a long time, complex in equipment operation and highin precision requirement are solved. A transducer is connected with an amplitude-change pole, the amplitude-change pole is arranged in a water cooling system, displacement of an energy converter in the horizontal direction and the vertical direction is realized through an energy converter walking platform, an electrode is arranged in a center hole of the energy converter in a penetrating mode, theupper portion of the electrode is fixed to an electrode walking platform through an electrode clamp, displacement of the electrode in the horizontal direction and the vertical direction is achieved through the electrode walking platform, a welding power source is connected with the electrode through a wire, and an ultrasonic power source is connected with the energy converter through a wire. Theultrasonic power source is controlled to output according to certain frequency, pulse ultrasound is obtained, and the pulse peak value and the base value are adjustable.

Description

technical field [0001] The invention relates to a novel pulse ultrasonic arc hybrid welding device and a welding method thereof, belonging to the technical field of arc welding and welding metallurgy. Background technique [0002] Arc welding has the advantages of simple operation, high production efficiency, and easy automation. It is widely used in manufacturing and industrial fields, including automobiles, aerospace, aviation, shipbuilding, navigation, weapons, energy and construction industries. In the development of arc welding technology, the main goal has always been to obtain better welded joints and higher welding efficiency. The shortcomings of traditional arc welding are mainly low welding efficiency, joint deformation, small penetration depth and coarse joint structure. [0003] Based on this, how to achieve high-quality and efficient arc welding technology has become a research hotspot. Ultrasound will produce a series of effects when propagating in the medium...
