Intelligent seam inspection for top quality laser welding
SeamControl is the advanced sensor system for optical laser weld seam inspection - based on the proven technology of the SOUVIS system and consistently further developed to meet the requirements of modern, networked production environments. With the help of AI-supported image processing and high-resolution sensor technology, the system detects even the finest geometries - even on inclined or highly reflective surfaces. SeamControl provides both the visual surface and the precise height profile of the weld seam in real time, thus sustainably increasing quality assurance in laser welding.
As a stand-alone system, SeamControl works independently of the welding station and can be seamlessly integrated into existing production lines. It detects surface defects and seam deviations with high precision and evaluates them automatically using predefined tolerances. The smallest gaps, surface pores or geometry errors are reliably identified and classified - good parts remain in the process, bad parts are specifically ejected. The result: maximum process reliability with a minimum reject rate.
Intelligent fault detection with real-time data fusion
What types of seams can typically be inspected?
Solder seams
SeamControl can be used to reliably inspect solder seams, such as those used in battery module and cell connector manufacturing. High-resolution quality monitoring ensures that stable and reproducible results are achieved even with fine seam structures and heat-sensitive materials.
Structural seams in safety-related applications
SeamControl is also suitable for downstream quality monitoring of structural seams, such as those used in automotive, bodywork, and mechanical engineering. Precise optical seam inspection after laser welding ensures the required strength and integrity of each welded joint and helps to identify rejects at an early stage.
Visible seams with high optical requirements
SeamControl can also be used to inspect visible seams in high resolution after the welding process, for example in household appliances, white goods, or design components. Camera-based quality inspection of welded and soldered seams ensures consistently high optical and functional quality.
Technical data
- Typical seam widths: Detection of weld and solder seam widths in the range from approx. 0.5 mm to 15 mm, depending on the variant / application
- Measurement of height differences: Precise detection of height variations of up to 17 mm, even with reflective or complex surfaces
- Defect detection at high speed: Thanks to an image frequency of up to 8 kHz, SeamControl reliably detects even small defects (e.g. surface pores or misalignment from approx. 100 µm) - even in fast processes with several meters per minute
- Flexible integration: Can be seamlessly connected to existing systems via the WeldMaster fieldbus interface
