Abstract

The invention discloses an acoustic-magnetic coaxial coupling regulation GTAW electric arc welding device and a welding method, and belongs to the technical field of welding and additive manufacturing. The problems that in existing electric arc welding, the electric arc energy is low, the component structure is thick and large, and the grain refinement effect in the prior art is not uniform are solved. The position of the acoustic-magnetic coaxial coupling device is adjusted through the welding gun control frame, the acoustic-magnetic coaxial coupling device comprises an ultrasonic transducer, an ultrasonic amplitude-change pole, a water cooling device and an electromagnet, the ultrasonic transducer and the ultrasonic amplitude-change pole are coaxially and fixedly connected in an end-to-end mode, and the electromagnet, the water cooling device and the ultrasonic amplitude-change pole are sequentially and coaxially sleeved from outside to inside, the top end of the ultrasonic transducer is fixedly installed on the welding gun control frame, and the tungsten electrode is coaxially arranged on the acoustic-magnetic coaxial coupling device in a penetrating mode. The sound field and the magnetic field can move synchronously with the heat source and the molten pool, the electric arc is compressed under the dual effects of electromagnetic force and acoustic radiation force, the electric arc energy is further improved, and the welding efficiency is greatly improved.

Description

technical field [0001] The invention relates to an acoustic-magnetic coaxial coupling control GTAW arc welding device and a welding method, belonging to the technical field of welding and additive manufacturing. Background technique [0002] Compared with many welding methods, arc welding has obvious advantages, such as high production efficiency, relatively simple operation, and low requirements for welding conditions. It is widely used in many industries, such as construction, automobile, shipbuilding, and aerospace industries. In the development of arc welding technology, the main goal has always been to obtain better welded joints and higher welding efficiency. In practical application, it can be found that traditional arc welding has disadvantages such as low welding efficiency, large joint deformation, small penetration depth and coarse joint structure. Based on the above problems, many researchers have developed a variety of arc hybrid welding methods. The basic idea...
