Automatic seam tracking by weaving
- This sensor allowes correction of curved workpiece or thermal distortion which can’t be corrected only by detecting workpiece position.
- Applicable to workpieces with medium thickness or thicker.
- Most inexpensive among all the tracking sensors.
- Easy to use from the viewpoints of interference of workpieces and maintenance because this sensor requires no additional parts around the torch. **Can’t be used for tracking on aluminum.
