Types of Laser Weld Seam Tracking Sensors
There are various types of laser weld seam tracking sensors,each designed for specific welding processes.The most common types include:
Single-camera sensor:This sensor system uses a single camera to capture images of the seam and guides the welding torch accordingly.
Stereoscopic camera sensor:This system incorporates two cameras positioned at a distance,capturing images of the seam from different angles.The captured images are then processed to provide an accurate representation of the seam's position.
Triangulation sensor:This system projects a laser beam onto the seam surface and uses a camera to measure the reflection for determining the seam's position.Triangulation sensors are suitable for detecting seams that may be challenging for other sensors to identify.
Vision sensor:Equipped with a high-resolution camera and powerful image processing software,this sensor provides accurate seam tracking.
Working Principles of Laser Weld Seam Tracking Sensors
Laser weld seam tracking sensors operate by capturing images of the seam and analyzing them to determine the seam's position.The sensor is mounted on the welding torch or an independent robotic arm that follows the welding torch.A laser beam is projected onto the seam surface,and the camera captures images of the reflected laser beam.Advanced image processing algorithms are then employed to analyze the captured images and determine the seam's position.
Different technologies are utilized to capture images of the weld seam.For instance,stereoscopic camera sensors use triangulation to determine the seam's position,while vision sensors employ image processing software to analyze images.The accuracy of the sensor depends on the chosen technology,camera resolution,and the complexity of the software.
