Process Monitoring in Laser Welding

Technologies and Systems for Precise Inline Quality Assurance

Stable laser welding processes are essential for reproducible quality and cost-effective series production. Precitec systems acquire quality-relevant process and weld data, detect deviations at an early stage and document the quality of every weld. This helps reduce scrap and rework and enables reliable quality decisions.

The portfolio covers different quality assurance tasks: The Laser Welding Monitor LWM monitors process signals inline, while LWM AI classifies defect types and predicts application-specific physical properties of the weld. Precitec IDM measures weld penetration depth directly during the process and enables closed-loop control. SeamControl inspects the finished weld optically and with AI support.

The systems are designed for industrial 24/7 operation and can be flexibly integrated into new or existing production lines. Process monitoring is used wherever high precision, short cycle times, leak-tightness or reliable documentation of safety-critical joints are essential – from automotive and e-mobility to energy storage, medical technology, consumer electronics, aerospace, mechanical engineering and home appliances.

The Laser Welding Monitor LWM provides the basis for inline monitoring of laser welding processes. Depending on the quality requirements, evaluation is performed conventionally by comparing process signals or with AI support using LWM AI. Both variants acquire and document every weld in real time and differ in the depth of their quality assessment.
