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
Seam inspection with AI support
SeamControl uses artificial intelligence to reliably detect defects such as joint misalignment, geometric deviations or pores - much more precisely than with conventional systems. The AI-based evaluation minimizes false evaluations, increases repeat accuracy and enables maximum detection rates - for maximum process reliability and quality.
Gray image and 3D data fusion in real time
SeamControl combines structured 3D height profiles with gray image information - in real time and perfectly coordinated. The simultaneous evaluation of both data sources enables a much more precise analysis of the weld seam quality. This means that defects are reliably detected even in complex seam situations - on several levels simultaneously.
Optimized depth of field and resolution
The new generation of sensors in SeamControl delivers razor-sharp images, even with complex component geometries or reflective surfaces. Thanks to optimized depth of field, the seam remains in focus even with inclinations or height differences - for reliable analysis without compromising on quality.
Typical areas of application

Soldered seams
e.g. in battery module or cell connector production, where fine seam structures and heat-sensitive materials require high precision
Structural seams
e.g. in car body construction or mechanical engineering - where the integrity of safety-relevant connections must be checked
Visible seams
e.g. for white goods, household appliances or design components where visual perfection is required
These seam types can be found in almost all industrial sectors - from classic car body construction and battery production to the manufacture of household appliances or complex machine components.
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
