Laser welding penetration monitoring system (IPM-OCT)
In the pursuit of exceptional efficiency and quality, does the laser-welding black box still cause problems? Unpredictable yield fluctuations? Process development that consumes time and materials? Defects discovered only afterward? The answer lies deep in the molten pool. The laser-welding penetration-depth monitoring system (IPM-OCT) goes beyond visibility to provide real-time control.

Applications
Traction batteries: cell-top covers, explosion-relief valves, terminals and module Busbar welding—consistent penetration is central to safety without worry. New-energy vehicles: welding of flat copper motor wires and battery trays to ensure strength and airtightness. Consumer electronics: phone midframes and precision structural components, where appearance and reliability are intrinsic requirements. Medical devices: sealing welds for implants and precision instruments—a promise of 100% reliability.
Key Features
Leading performance targets: measurement accuracy (≤10μm), detection speed (up to 250kHz) and control latency (<1ms) are benchmarked against, and intended to surpass, references such as IPG LDD for demanding applications including high-speed power-battery welding. Deep integration and open compatibility: standardized integration with mainstream lasers (IPG, TRUMPF, Raycus, Maxphotonics and others), robots (KUKA, ABB and others) and PLCs, with MES connectivity for digital workshops. Intelligent operation and local support: a simple, intuitive Chinese interface with powerful data-analysis tools, supported by responsive local technical and process-service teams.
