CalibrationLine

Measurement and calibration systems for laser beam characteristics

Detect deviations in laser parameters before they affect the component

Even a precisely calibrated laser system changes over time: temperature drift, contamination, or maintenance can cause it to no longer meet defined set values. When welding and surface processing, CalibrationLine measures the power and focus position at defined intervals, detects such deviations early, and reports them to the control, which makes adjustments before component quality is compromised. The measured values are automatically recorded and remain fully traceable.

CalibrationLine Focus

Checking and setting the focus position

Checks at user-defined intervals whether the focus position on the workpiece still meets the specifications

Compares the measuring data with the set values using the TruControl control software and automatically corrects the focus position if there is a deviation

CalibrationLine Focus in use

Welding rear seats

Rear seats have varying sheet thicknesses and geometric tolerances. This leads to focus deviations in the welding process, which must be manually readjusted on a regular basis, resulting in costly production downtimes.

CalibrationLine Focus automatically checks the focus position between welding processes and recalibrates, even with varying sheet thicknesses and structural components. This ensures a consistent weld quality across all weld points, minimizes idle times, and increases availability.

CalibrationLine Power 

Checking and setting laser power

Checks at user-defined intervals whether the laser power on the workpiece still meets the specifications - for example, after changing the optics or if the protective glass is dirty

Compares the measuring data with the set values using the TruControl control software and automatically corrects the power if there is a deviation

CalibrationLine Power in use

Welding of automobile bodies

When welding automotive body components, the laser power may deviate from the defined set values due to long production runs, variations in material and geometry, or contaminated optics. This affects the quality of the weld seam.

CalibrationLine Power monitors the laser power at customizable intervals, detects deviations, and automatically corrects them. The laser power remains within the defined limits thus reducing rejects and rework.

Welding of hairpins

When laser welding hundreds of hairpins per layer, a constant laser power is essential. During long production runs, there is a risk of power loss due to heavy copper spatter, smoke, and dirt buildup on the protective glass. This results in faulty hairpin connections that subsequently cannot be repaired.

CalibrationLine Power continuously monitors the laser power and automatically corrects deviations. This allows you to ensure optimum connection quality for every hairpin and drastically reduce rejects, especially at high production volumes.

Laser surface processing: Cleaning batteries

Battery cells must be free of oxide films before welding. Different materials (aluminum, copper, nickel) and geometries make it difficult to achieve consistent cleaning results, causing focus deviations during surface processing.

CalibrationLine Focus automatically checks the focus position before each laser cleaning process and makes adjustments. This ensures a consistent cleaning quality across all cells - a prerequisite for reliable, reproducible welding processes without rejects.
