Arc pressure induction automatic welding head device

Abstract

The invention discloses an arc pressure sensing automatic welding head device which comprises a welding head and a control module. The control module comprises a power supply control module and a motor speed reduction module; the power supply control module comprises an auxiliary power supply module, an arc pressure power supply module and a power supply switching unit; when the welding head is in a standby state, the auxiliary power supply module is adopted to supply power to the welding head; when the welding head starts to work, the auxiliary power supply module is switched off and the arc pressure power supply module is adopted to supply power to the welding head; switching between the auxiliary power supply module and the arc pressure power supply module is carried out by the power supply switching unit; the motor speed reduction module acquires state information of the welding head in real time so as to regulate a wire feeding speed or a welding wire melting rate of the welding head. The arc pressure sensing automatic welding head device disclosed by the invention has strong adaptability and is simple to operate.

Description

technical field [0001] The invention relates to the technical field of welding control, in particular to an arc voltage induction automatic welding head device. Background technique [0002] With the development of welding technology, it has become a very important means of metal processing in today's industrial production.

Problems solved by technology

[0003] The control technology of automatic welding head at home and abroad basically adopts constant speed or variable speed adjustment mode, which are respectively matched with constant voltage flat characteristic welding power supply (CV) or constant current falling characteristic welding power supply. The length is limited by the voltage drop of the power supply circuit, and the adaptability to large working surface and long-distance welding scenarios is poor; in addition, there are welding materials or welding wire diameters that have poor adaptability, making operation and control difficult
