Problems solved by technology

[0005] (1) Complex structure
The traditional pulse MIG welding power source is controlled by an analog control system, with a large number of components, complex structure and large volume
[0006] (2) The control is not flexible enough and accurate
The traditional analog control system has limited ability to perform complex processing, the number of components is large, and the parameters of the control system are determined by the parameters of discrete components such as resistors and capacitors. The control system is complicated to debug and has poor flexibility. The consistency of the system, the stability of the parameters is poor, such as temperature drift affects the stability of the control system

Abstract

The invention discloses an MIG welding power supply system based on STM32. The MIG welding power supply system comprises an inversion main circuit and a control circuit. The inversion main circuit comprises an input rectifying filter module, a high-frequency inverting module, a power transformation module and an output rectifying filter module which are sequentially and electrically connected. The control circuit comprises an SMT32 digital control module, a voltage-current detecting module, a fault protecting module, a man-machine interface module and a high-frequency drive module. The man-machine interface module realizes welding parameter giving through a digital pulse encoder. The MIG welding power supply system has the advantages that an STM32 chip is used to control the pulse MIG welding power supply system, system structure is simple, the control function is achieved through software, high anti-interference capability is achieved, and the problems that traditional pulse MIG welding power supply system is complex in structure, large in size, and inaccurate in parameter giving, and the like are solved.

Description

technical field [0001] The invention relates to a pulse MIG welding power supply system based on STM32. Background technique [0002] Pulse MIG welding technology is mostly used in high-performance automatic welding occasions. It integrates high efficiency, high quality and automation. Its outstanding process features are: the welding current adjustment range is relatively wide, that is, pulse MIG welding can be used when the average current is less than the critical current value. The jet transition is obtained under the conditions, including all the current regions from the short circuit transition to the jet transition; the molten pool is small, the molten droplet transfer and the heating of the molten pool metal are intermittent, and dripping is not easy to occur, and the horizontal welding and vertical welding can be successfully completed. It is conducive to the realization of all-position welding; the controllability of the droplet transfer process is relatively stron...
