Plasma phenomena during Nd-YAG laser welding

Conference ·
OSTI ID:5313611
The plasma plume formed during welding with a pulsed Nd-YAG laser attenuates the laser radiation and directly affects weld penetration. The attenuation is proportional to the intensity of the plasma and, therefore, increases with increase in the gas pressure of the working environment. As the intensity of the plasma increases, heat radiation from the plasma becomes a significant factor contributing to the size of the melt zone.
