The laser tracking sensor is used for reliable automatic tracking of the weld edge. It is mounted in front of the torch, which moves based on the sensor information. The lasers are capable of detecting the width, depth and other parameters of the joint, with a display of the tracking status and edge shape in real time via the software. It also works on uneven weldments (pipes The software displays the detected weld shape and the weld edge. In the software the temperature of the sensor is monitored. Tracking helps the operator to ensure quality welds. During welding, it corrects the direction and height of the torch using the motorised cross sled (2-axis). Parameter combinations are possible machine and tracking on the same screen. The limitation for the tracking may be shiny stainless steel, in such cases we suggest a special type sensor. Depending on the application requirements we will recommend the most suitable type.
