Description

Technical field [0001] The invention relates to a dual-processor communication control system based on MCU single-chip microcomputer and DSP digital signal processing, in particular to a control system and control method for micro-beam plasma welding. Background technique [0002] Generally, micro-beam plasma welding is a relatively complicated welding process method in welding equipment. The hardware equipment that realizes the welding process of this method includes water circuit, shielding gas, ion gas, small arc power supply, main arc power supply, arc ignition device, etc. The welding process is an open working process, which is affected by many external factors. At the same time, because multiple control parameters control the welding process, these control parameters interact with each other, which makes the welding process more uncertain. Welding quality, real-time collection and processing of a large amount of field information, and the realization of optimized combinati...
