Robot and intelligence is the tendency of welding technology. The key to intelligence is, in real-time, to acquire welding pool formation and adjust welding technology to assure the formation uniform. Shape from shading is the effective method to acquire the 3D formation of the welding pool. The reflectance map model of aluminum alloy pulse GTAW welding pool surface, resolution of reflectance map equation and calculation of the welding pool surface height is introduced. The calculation result can testify the characteristics of the welding pool.
