Line Laser Process Monitoring
In-process laser monitoring uses a laser scanner to capture the weld geometry during solidification. It immediately detects irregularities, thus improving weld quality.
Physical-Chemical Mechanism of Action
The seam laser process monitoring uses a laser scanner to capture the shape and size of the weld seam in real time. The laser sends a light beam signal onto the seam and measures the feedback to determine the geometry.
Metallurgical Relevance & Risks in Welding
Monitoring the seam geometry is critical for the quality and safety of the welding process. Irregularities in shape or size can lead to cracks, wear, or distortion. Immediate detection of such issues by the seam laser process monitoring allows quick correction and improves the overall calibration of the welding equipment.
Workshop Practice & Action Instructions
To use seam laser process monitoring successfully, the laser scanner must be properly aligned and calibrated. The scanner position should be arranged so that it covers the entire seam. When deviations in seam geometry are detected, take immediate action to calibrate the welding equipment or adjust process parameters. Recommended values for the scanner position are at least 5 cm before and after the start of solidification.
