激光焊接时等离子体电流的产生机制及其数学模型
Mechanism and Mathematical Model of the Laser-induced Plasma Currentin Laser Welding
摘要
通过对激光焊接时等离子体产生机理的分析,从等离子体物理理论的角度出发,建立了适应于激光焊接等离子体电特性的数学模型.该模型能够较好地解释等离子体电信号随喷嘴-工件距离的增加而单调减小的规律.
Abstract
This paper analyses the mechanism of the laser induced plasma current and establishes a mathematical model for laser welding. The model satisfyingly interprets the regularity of the plasma charge signal decreasing monotonously with the increase of the nozzle workpiece distance, which coincides well with the experimental results.
