A novel two-color pyrometer composed of a high-speed shutter TV camera and an image intensifier is employed to study the surface temperatures of the cladding layer under CO2laser radiation. The two dimensional image of the surface temperature of the melt pool was stored in the frame memory in National Television System Committee (NTSC) formula. Also, high-speed photography was used to observe the dynamic behavior of the melt pool. The rapid motion and temperature change of the melt pool were observed and the former was greater than the laser scan (200 Hz). From these two time-resolved measurements, the laser cladding layer was found to be under the control of the dynamic behavior of the melt pool.
