Common Sensors in Laser Welding
Vision Sensors: Vision sensors use cameras to monitor the seam position, seam width, and the molten pool state during the welding process in real time. This helps operators adjust welding parameters in a timely manner, ensuring welding quality.
Laser Displacement Sensors: Laser displacement sensors scan the surface of the welded parts with laser beams, measuring the seam position, seam depth, and the geometric shape of the seam. The high-precision measurement capability of these sensors plays a crucial role in the welding process.
Temperature Sensors: Temperature sensors are used to monitor the temperature of the molten pool and the heat-affected zone during welding, ensuring the welding temperature remains within a reasonable range to prevent defects caused by overheating or rapid cooling.
Infrared Sensors: Infrared sensors detect the intensity of infrared radiation in the welding area, monitoring the temperature distribution and heat input during the welding process in real time.
Application of Laser Displacement Sensors
In the laser welding process, laser displacement sensors are high-precision measurement tools that can monitor displacement and deformation in real time. The main functions of laser displacement sensors include:
Seam Tracking: Laser displacement sensors can monitor the seam position in real time, ensuring the welding torch always welds in the correct position. This is especially important for automated welding, significantly improving welding efficiency and quality.
Seam Shape Monitoring: Laser displacement sensors can measure the geometric shape of the seam, ensuring the seam width and depth meet predetermined requirements, thus avoiding quality issues caused by seams that are too wide or too narrow.
Welding Defect Detection: Laser displacement sensors can identify surface irregularities, cracks, and other defects in the seam, providing feedback to operators or automatic control systems for adjustments or repairs, ensuring welding quality.
