BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for simulating an electric arc welding, a welding drill in a CO 2 protective atmosphere, and for simulating aluminum welding in an argon protective atmosphere.

The previously known welding simulation devices utilize the position of the electrode tip relative to the movable target, which is mechanically coupled to the target free movement device (U.S. Pat. No. 4,041,615). In this case, it evaluates the time for which the test person has kept the target in the degree of freedom that is ideal for welding. The solution uses an electrode to simulate welding, which is ultimately provided with a magnet. The magnet, when moving in the electric field, causes changes to be made to the instruments against the pre-set values, which are ideal welding conditions (U.S. Pat. No. 4,124,944). In another case, the light of the bulb located at the end of the electrode is welded to simulate a moving target, from which light is reflected and a light pattern is formed, the shape of which is determined by ideal welding conditions (U.S. Pat. No. 4,132,014).

The possibilities of the previously known solutions are further expanded by an electric arc simulation device according to the invention, characterized in that it consists of a control panel of a voltage source equipped with control and protection elements, to which a positioner enabling the attachment of electrographic paper is attached. The electrographic papier serves to record the movement of the electrode fixed in the handle or the weld wire fixed in the handle. The conductor holder or sleeve is connected to a control panel from which the required control voltage is fed.

The device according to the invention makes it possible to simulate practically 2 237 683 all the situations that occur in the welding process, and wraps the entire process from ignition to compliance with the exact distance of the wound, the prescribed weld drawing, to the complex function of the associated operations. As opposed to the traditional welding process directly by the welding equipment, the device according to the invention makes it possible to save a large number of metallic materials, electrodes, electrical energy and the welding equipment itself.

FIG. 1 shows a front panel of a power supply control panel with actuators, FIG. 2 shows a positioner with a stand, FIG. 3 shows an electrode sleeve with an electrode, FIG. CO 2 welding, Figure 5 shows the overall assembly of the device for simulating welding.

On the stand 21 of the positioner 20 is mounted a base plate 22, which is a HV conductor 25 connected to a plug 1 on a control panel 10 of a voltage source which is connected to the network. When the power button 1 is pushed in, the green light comes on. The function switch 6 switches to the desired position of the function shift, which is: position 1 - electrode feed without tension, position 2 - HV electrode without electrode feed, position 3 - electrode-assisted voltage, position 4 - HV voltage with ignition ignites electrode-free, position 5 - HV voltage with arc ignition and post-electrode, and position b is free.

Pressing the button 32 on the holder 30, respectively. 41, the desired function set on the function switch 6 is actuated by the nozzle 40 (FIG. 4). In the case of a high voltage operation, ie in welding or in the event of a malfunction, the red indicator light 2 on the control panel 10 lights up. with element 7, the sensitivity setting 1 when the ignition is being trained. Simulating the welding current and simultaneously controlling the speed of the electrode 38 is provided by the regulator 2 on the control panel 10 of the voltage source. After the cloud breaks, the electrode feed is stopped, the MV is switched off, and the red indicator light 2 is turned off.

The simulation of welding itself is carried out on electrographical paper 21, which is fastened to the foundation plate 22, · 2 · 237 683 by the clips 24

Holder 30 serves to simulate electrode welding. A drive unit is located in the handle 31. The passage of the welding passage is controlled by the pushbutton 22. Through the gear box 33, a movement of the electrode 38 is provided which simulates the melting of the electrode during simulation, the electrode 22 is provided with stop plates 39 on both ends which return to the end switches 37 the electrode 38 d ' of the starting position for welding, thus simulating the incorporation of the new electrode. The locking screw 34 can be used to insert the pressure pads in the transmission housing 33 for possible manual return of the electrodes of the initial position. The welding current and the tension controller are fed through the power cord 22 through a plug 36 which is inserted into the control panel socket 8.

To simulate the welds in the CO 2 shield, a nozzle 40 with a nozzle according to Figure 4 is used. The pushbutton switch 41 controls the power supply to the welding wire 42. The welding current is fed through the cord 42 through a plug 44 which is inserted into the socket 8 by a control panel 10 of the voltage source.

To simulate the welds, a L-shaped base plate 22 is used. A simulation of the roughing of the coarse materials is carried out in a jig where the electrographic paper is held in the pinch by a pressure drot.

The electric arc welding simulation device is used in basic welding courses, it can be used to weld welds in high-power welders or to detect errors in welds after x-ray welding.
