  • the angular position sensor (2) measures the angle of stance of the sheet metal surface to be welded by attaching the same to the welding torch head (6) and thus keeping the torch perpendicular to the surface when a measurement button (5) is pressed, transmits it to the control card (4) and records it.
  • the measured sheet surface angle is recorded and the position of the surface normal is determined as the zero position by means of the angular position sensor (2), and the LEDs (3) in the colors determined in the software are turned on and off to warn the operator for the different angular deviations of the laser beam / manual welding torch (1 ) from this position.
  • the data coming from the angular position sensor (2) is processed on the control card (4) with the help of software and the RGB LED (3) warns the operator with different colors in the angular intervals specified in the software and the operations required for the opening and closing of the trigger button are carried out by the control card (4).
  • the measurement button (5) is pressed and the direction of the surface normal is measured and recorded by the control card (4). In this way, the angular position of the surface to be welded or any desired position is determined as the angular zero position
  • the welding torch head (6) is attached to the tip of the manual welding torch (1 ) and provides a flat, wide surface that allows it to be held in such a way that the laser beam direction is perpendicular to the sheet surface to be welded. Such a head is needed since the end of the laser beam is very narrow.

  • the circuit diagram of the device which is preferably created using the arduino Pro Micro control card and the MPU6050 angular position sensor (2), is given in Figure 1 c (The system can also be produced using different control cards and different angular position sensors).
  • the angular position of the torch is continuously measured with the aid of the angular position sensor (2) located at the top of the torch along the direction of the laser beam and according to the angular state of the torch, the operator is warned about the angular position with different colors with the help of the RGB LED (3).
  • the angular position sensor (2) can also be placed at a different point on the welding torch, but this selection may reduce the accuracy of the angular position measurement.
  • the holding angle of the torch should be adjusted according to the angle of the surfaces to be welded ( Figure 2a). For this reason, before starting the welding process, the stance angle (surface normal) of the sheet surface to be welded should be measured. This measurement can be taken without the need for an external device by attaching the welding torch head (reset plug) (6), which allows the tip of the smart welding torch to be held perpendicular to the surface ( Figure 2b). The surface area that will enable the torch to be held perpendicular to the surface is obtained with the help of the welding torch head (reset plug) (6) attached to the tip of the torch.
  • the angles in this starting position are recorded by the control card (4) with the help of the measurement button (5) on the device and the surface normal is calculated with the angle values obtained from the angular position sensor (2).
  • This calculation is done as follows: the angular position sensor (2) provides angle information in the range of 0-360 degrees from the three axes. Only two of these angle values (x, y) are sufficient to calculate the direction of the surface normal. While the surface normal changes in the range of 0-180 degrees, the sensor needs angular transformation to measure in the range of 0-360 degrees.
  • the direction of the source surface normal can be easily calculated with the help of the converted two angle information and the cosine theorem.
  • the surface angle measurement button (5) When the surface angle measurement button (5) is pressed, the measured initial values are continuously subtracted from the next values and the angle between the welding torch (laser direction) and the surface normal is continuously calculated in the time interval determined in the software.
  • the RGB LED at the tip of the torch warns the welding operator as red ( Figure 2c), green ( Figure 2d) and blue ( Figure 2e) according to the limit values of the angles (0A, 0B and 0C) determined in the program. In this way, the operator can perform the welding process in the right position or the welding process can be performed automatically when the welding torch position comes to the appropriate angle. Performing the process automatically allows welding in a much more precise narrow angular range. This process can also be performed automatically when the appropriate angle is caught without pressing the trigger. In this way, the operator will not waste time to catch the right angle.
