CO 2 GMAW welding manipulation simulator

The invention provides a welding operation simulator for CO2 gas shield arc welding. The simulator comprises a control cabinet, an operation console, and a simulation welding gun. The simulation welding gun includes a welding gun rod, a handle, an arc plastic housing, an electric touch pen, a spring, a mobile copper sheet, an inductive proximity switch, an inclination angle sensor, and a nozzle. One end of the electric touch pen is fixedly connected with the mobile copper sheet and the electric touch pen passes through a center of the nozzle that is connected with the mobile copper by the spring. The inductive proximity switch is installed at one end of the welding gun rod and the double-shaft inclination angle sensor is installed at the other end of the welding gun rod. One end of an insulating cylinder is sleeved around the periphery of the nozzle and the other end of the insulating cylinder is sleeved around the periphery of the welding gun rod, wherein the inductive proximity switch is installed at the welding gun rod. One end of the arc plastic housing is connected with the welding gun rod and the other end of the arc plastic housing is connected with the handle. The inductive proximity switch and the double-shaft inclination angle sensor are connected with a computer in the control cabinet; besides, the operation console comprises a touch screen that is used as a welding test panel, wherein the touch screen is connected with the computer in the control cabinet. According to the invention, a training cost is substantially reduced; meanwhile, the training can be carried out safely and efficiently.
