Method of simulating a welding process

摘要

The device (1) comprises a computer (2) having an input device (11) and an output device (6), a welding torch, a magnetic position monitoring device (5) having a transmitter and sensors, a retaining device for a workpiece used for the simulation, and a visualization device for generating two- or three-dimensional image on the output device. The retaining device has a recess, into which the workpiece is inserted. The transmitter of the position monitoring device is arranged below the recess at a small distance from the workpiece. The retaining device is designed as a small, portable box. The device (1) comprises a computer (2) having an input device (11) and an output device (6), a welding torch, a magnetic position monitoring device (5) having a transmitter and sensors, a retaining device for a workpiece used for the simulation, and a visualization device for generating two- or three-dimensional image on the output device. The retaining device has a recess, into which the workpiece is inserted. The transmitter of the position monitoring device is arranged below the recess at a small distance from the workpiece. The retaining device is designed as a small, portable box to be placed on a table. The box and the workpiece is made of electrically and magnetically non-conducting plastic material. The transmitter is arranged below the workpiece at the central position of the retaining device, so that the distance of the transmitter to the sensor in the welding torch is minimized during simulating the welding process. The box is formed with the workpiece for the simulation of horizontal welding and vertical welding. The workpiece and the box are equipped with a radio frequency identification chip and a radio frequency identification laser. The marked areas for an entry over the welding torch are arranged at the box. The areas are formed as verification switching area, replication switching area, menu switching area and reverse switching area, so that the corresponding command is implemented to the computer during positioning and activating the welding torch. The welding torch is built up by a torch handle and a pipe elbow and has pipe connection for the computer. A sensor is arranged in the area of a torch tip for determining the position. A movably mounted pin is arranged at the torch tip for simulating a welding wire. A starting switch is arranged at the torch handle for activating the simulation of the welding process. A switching element is arranged at the torch handle for adjusting the predetermined welding parameters such as wire feed, voltage and current. A welding shield or a cap, at which the sensor is arranged, is connected with the position monitoring device and/or the computer. The control of the camera over the position monitoring device takes place for the visualization of the scene on an image screen. Polhemus-sensor is arranged at a welding helmet and/or at the cap and Polhemus-transmitter, over which the position of the camera is determined, is arranged in the workpiece. A case is provided for the arrangement of all components. Independent claims are included for: (1) a method for generating two-dimensional images on an output device over a visualization device for simulating a welding process; and (2) a method for controlling a simulated welding process.
