- Product Description
Product Introduction
The LAW-20000L9-MIG intelligent laser-arc hybrid welding system is designed for welding medium to thick plates. Equipped with a 6-axis robot (expandable with external linear or rotary axes) and a large-scale motion mechanism, the system offers flexible and adjustable welding ranges. Integrated with a 20 kW fiber laser and a 500 A digital CMT/MIG welder, it enables synergistic welding using dual heat sources—laser and arc—significantly improving welding efficiency, quality, and adaptability. The system supports intelligent features such as laser vision-based seam tracking, digital twin of welding paths, pre-weld path simulation, and closed-loop parameter adjustment. Additionally, it can be equipped with coaxial molten pool online monitoring, providing real-time feedback on penetration depth and defect information during welding. The entire processing workflow enables data collection, analysis, storage, and traceability, allowing fully digitalized management throughout the process.

Product Advantages
Compact and flexible
●The cantilever structure combined with a 6-axis robot results in a smaller footprint; the cantilever structure is highly flexible and can reach further.
Thick plate without beveling
● 20kW high-power laser + MIG combination: Industry-leading power level, 20mm carbon steel single-pass penetration welding, truly achieving bevel-free welding
Adaptive tracking
● Laser vision adaptive tracking: ±15mm assembly error tolerance, gap tolerance of 0.5~1mm
High strength with low defects
● Laser deep melting with low heat input + OCT online monitoring, Laser-MIG combined thermal regulation + OCT online monitoring, resulting in higher welding joint strength and lower defect rate
Digital Interconnection
● Compatible with mainstream communication protocols (such as ModBus TCP/EtherCat, etc.), complete data collection and remote monitoring throughout the process, seamless integration with the digital factory platform
