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 result in it no longer meeting defined set values. In welding as well as in surface processing, it measures CalibrationLine measures 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 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 of 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 idle states.

CalibrationLine Focus automatically checks the focus position between welding operations and recalibrates it – even with varying sheet thicknesses and structural components. This ensures consistent weld quality across all weld points, minimises idle time, and increases availability.

CalibrationLine Power

Checking and setting laser power

Checks at user-defined intervals whether the laser power on the workpiece still meets 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 dirty optics. This affects the quality of the weld.

CalibrationLine Power monitors laser power at customisable intervals, detects deviations, and corrects them automatically. Laser power remains within the defined limits – reducing rejects and rework.

Welding hairpins

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

CalibrationLine Power continuously monitors the laser power and automatically corrects any deviations. This allows you to ensure optimal connection quality for every hairpin and drastically reduce rejects, particularly at times of high demand.

Laser surface processing: cleaning batteries

Battery cells must be free of oxide layers before welding. Different materials (aluminium, copper, nickel) and geometry make it difficult to achieve consistent cleaning results – resulting in focus deviations during surface processing.

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