WELDCHECK 4.1.
Process monitoring and quality assurance for laser welding
The WELDCHECK system detects the (emitted) process light from the welding process in a wide spectral range. It analyzes and compares the weld in real time with trained reference welds that have been judged to be good. If the system detects a deviation from the standard, the weld is considered defective. Tolerances can be set flexibly. The system is used for automated control to reduce inspection costs and increase output.
Typical detectable errors are:
- Deviation of laser energy
- Contamination of optics and protective glass
- Faulty focus position
- Joining gap too large
- Positioning error
- Change of welding depth
- Contamination of the surface
- Weld penetration
In use worldwide for more than 20 years, WELDCHECK enjoys unbroken demand. The current WELDCHECK 4.1 model offers a compact design, convenient operation and easy connection to fieldbuses.
The system consists of a sensor and the evaluation unit (EVA).
Thanks to its compact design and by means of so-called ModSets (adaptation options), WELDCHECK 4.1 can be integrated in a space-saving and elegant manner in the beam source or in all common processing optics.
The following video shows how easy it is to put WELDCHECK 4.1 into operation, using integration into a Trumpf TruDisk laser as an example.
