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.
