A welding robot teaching system which can secure welding quality of the robot even before the actual panel teaching by performing teaching of a robot although an actual panel of a new car is not used, and can greatly reduce a line preparation time by reducing teaching time is provided. A welding robot teaching system comprises: a computer(1) into which three-dimensional size information and three-dimensional welding point positional information of a new car panel are inputted; a data converter(2) for converting the three-dimensional size information and the three-dimensional welding point positional information of the panel received from the computer into hologram projection data and laser multi-point projection data respectively; an imaginary panel projector(3) for receiving the hologram projection data from the data converter to project an imaginary panel(8) into a space as a hologram; and a welding point projector(4) for receiving the laser multi-point projection data from the data converter to project welding points(9) on the imaginary panel projected into the space by the imaginary panel projector.
