Abstract

The invention belongs to the technical field of welding equipment, and discloses a low-frequency sound field regulation type swing arc tungsten-electrode argon arc welding device and method. The device comprises a welding gun, a gas cover, a tungsten electrode, a connecting part, a guide rod and a sound wave generator, wherein the gas cover is connected with the welding gun, the connecting part isused for being connected with the tungsten electrode and the welding gun, the guide rod is connected with the tungsten electrode, the other end of the guide rod is connected with the sound wave generator, an electric connecting port is formed in the welding gun, and an air inlet is formed in the gas cover. According to the low-frequency sound field regulation type swing arc tungsten-electrode argon welding device, the sound wave and the tungsten electrode argon arc welding are combined, the sound wave generated by the sound wave generator is transmitted to the tungsten electrode through the guide rod, and the tungsten electrode drives the electric arc to perform pendulum motion. The swinging of the tungsten electrode is beneficial to heating of the side wall of the electric arc, the problems that the existing narrow-gap welding technology is difficult to overcome and the defects of the cold wall and the side wall are poor are solved, and meanwhile, the complex structure of original narrow-gap welding equipment is simplified, the equipment cost is reduced, the splashing is reduced, the problem that a narrow-gap GMAW welding seam is poor in forming is solved, and high-efficiency welding and high welding seam forming rate are achieved. The device is used for narrow-gap welding.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a low-frequency sound field control swing arc tungsten argon arc welding device and method. Background technique [0002] With the increasing scale of modern industry, the application of thick plate and ultra-thick plate structure is becoming more and more extensive. In the manufacture of metal structural products such as ships, pressure vessels, boilers, rails, and large-scale engineering construction site operations, the traditional automatic welding methods for thick plate joints generally use large-groove multi-layer multi-pass welding or submerged arc welding, and the welding efficiency is low. The consumption of welding consumables is large and the welding cost is high, which can no longer meet the requirements of modern industry for welding. Narrow gap welding is a highly efficient and energy-saving welding method. The use of narrow grooves can great...
