Problems solved by technology

[0003] However, in the high-efficiency TIG automatic wire-filling welding process, due to external interference or arm fluctuations, the arc height (arc voltage) will inevitably change during the welding process. The welding bead is discontinuous. If the arc voltage is high, the welding wire will melt in the arc space. Due to the mutual attraction of the same direction current, the droplet will be attracted in enough arc space, resulting in the droplet sticking to the tungsten electrode and burning the tungsten electrode. welding quality

Abstract

The invention provides an efficient TIG wire feeding method and a welding device. The wire feeding method comprises the steps that a standard arc pressure is preset; wire feeding is conducted at the preset wire feeding speed, and the real-time arc pressure in the welding process is detected; whether the absolute value of the difference value between the real-time arc pressure and the standard arc pressure is larger than a preset value or not is judged; if the real-time arc pressure is larger than the preset value, the wire feeding speed is adjusted according to the real-time arc pressure, the preset wire feeding speed and a preset rule; and wire feeding is conducted according to the adjusted wire feeding speed. According to the efficient TIG wire feeding method, the wire feeding speed can be automatically adjusted according to the feedback arc pressure in the welding process, wire feeding can be stable, and welding seam forming can be excellent.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular, to a high-efficiency TIG wire feeding method and welding equipment. Background technique [0002] Efficient TIG (Tungsten Inert Gas Welding, non-melting inert gas tungsten shielded welding) welding technology is developed from traditional TIG welding. High-efficiency TIG is based on the traditional hot wire TIG welding, through the servo motor to control the forward and reverse of the wire feed wheel to achieve the effect of vibrating wire feeding, which can not only realize automatic wire feeding, but also endow the The forward-feeding welding wire has the function of linear vibration along its own direction. On the one hand, the molten droplet is actively separated from the welding wire and enters the molten pool. It is beneficial to the discharge of gas and inclusions in the molten pool, and increases the movement of liquid metal during the crystallization process, th...
