Other AbstractThe invention relates to a basic plate preheating system of laser metal deposition shaping. The basic plate preheating system comprises a basic plate pre-heater and a temperature control device thereof, wherein, the basic plate pre-heater has a box structure and is provided with a bottom plate, internal walls and external walls arranged around the bottom plate; heat insulating materials are arranged between the internal walls and the external walls; an electric heating pipe is installed on the bottom plate by the heat insulating materials and copper plates are arranged in the box body and overthe electric heating pipe; and a wiring terminal of the electric heating pipe is connected with the temperature control device. The basic plate preheating system provides a stable temperature field for the laser metal deposition shaping technique, effectively reduces the temperature gradient of a sample and the basic plate during the shaping, and has high automation, good uniformity in preheatingof the basic plate and high control precision, thus providing an effective solution to cracks or even breaks existing in the laser metal deposition shaping technique.
