Marine Engineering Ultra-Thick Plate · 20000W

Marine Engineering Ultra-Thick Plate Fiber Laser Cutting Machine

The Marine Engineering Ultra-Thick Plate Fiber Laser Cutting Machine from Shandong Xinhong CNC is configured specifically for shipyards and offshore engineering fabricators processing ultra-thick steel plates. Built on a 20000W IPG/RAYCUS laser platform with a reinforced heavy-duty gantry and high-pressure nitrogen cutting system, it cuts carbon steel up to 50mm, stainless steel up to 30mm, and marine-grade alloys with the edge quality and dimensional accuracy required by classification society standards (DNV, ABS, LR, BV). The 2000×6000mm working area accommodates full-size shipyard plates without pre-cutting.

Buyer Pain Points & Solutions

Oxy-fuel and plasma quality limitations: Shipyard plate cutting traditionally relies on oxy-fuel and plasma for 30-50mm carbon steel - processes that leave scale, wide kerf, rounded top edges, and large heat-affected zones requiring extensive grinding before welding. The 20000W fiber beam produces narrow, square edges with minimal HAZ, dramatically reducing weld preparation time.

Classification society compliance: Marine fabrication requires cuts that meet classification society standards (DNV, ABS, LR, BV). The fiber laser's precision cutting (±0.05mm positioning, ±0.03mm repeatability) and clean edge quality support compliance with these stringent dimensional and surface standards.

Marine-grade alloy processing: Offshore engineering uses specialized alloys including duplex stainless steel and marine-grade aluminum that are challenging for traditional cutting methods. The 20kW beam with high-purity nitrogen assist gas processes these materials with bright, oxide-free edges ready for welding.

Core Advantages

IPG / RAYCUS 20000W laser source - 50,000+ hour sealed tube life. The 20kW beam delivers sufficient power density for clean, single-pass cutting of 50mm carbon steel - replacing oxy-fuel with superior edge quality and faster throughput.

30 bar high-pressure gas delivery system - Engineered for thick-plate cutting with nitrogen assist gas. High-pressure nitrogen (≥99.99%) produces bright, oxide-free edges on stainless steel and marine alloys up to 30mm. Compatible with Xinhong's PSA nitrogen generator.

Reinforced thermal management - Triple-circuit industrial water chiller with dedicated cooling for laser, optics, and cutting head. Maintains thermal stability under 20kW continuous operation for extended shipyard production shifts.

Heavy-duty dual-drive gantry for thick plates - Reinforced welded steel frame with stress relief, dual servo motors on X-axis. Engineered for the thermal and dynamic loads of 50mm plate cutting with ±0.05mm positioning accuracy.

Schneider Electric CNC with shipyard production management - Modicon M241 PLC with Ethernet for remote monitoring, batch scheduling, nesting integration, and production data logging supporting traceability requirements.

Manufacturer Backing

Manufactured by Shandong Xinhong CNC Technology Co., Ltd., established in 2005, an ISO 9001:2015-certified and CE-compliant fiber laser equipment manufacturer. Xinhong's production facility is equipped with high-power laser cutting systems from 2000W to 30000W, serving automotive, electrical, and heavy industry sectors worldwide. This marine engineering configuration is built on the 20000W platform with specialized thick-plate cutting optimizations. Laser sources from IPG (USA), RAYCUS, and GW. Technical documentation, operation manuals, operator training, and commissioning guidance are provided with every machine.

FAQ

How does this machine differ from the standard 20000W model?

This marine engineering configuration includes a 30 bar high-pressure gas delivery system (vs 25 bar standard), triple-circuit chiller for extended thick-plate duty cycles, and specialized cutting parameters optimized for shipyard plate materials including marine-grade carbon steel and duplex stainless steel. The gantry is additionally reinforced for continuous heavy-plate processing.

Can it cut duplex stainless steel used in offshore applications?

Yes. The 20000W beam with high-purity nitrogen assist gas cuts duplex stainless steel up to 25mm with bright, oxide-free edges. Duplex steel's higher strength and viscosity compared to standard austenitic stainless require the additional beam power for clean cutting.

Does the machine support classification society requirements?

The machine's ±0.05mm positioning accuracy and clean edge quality support dimensional and surface requirements of major classification societies (DNV, ABS, LR, BV). However, final certification depends on your specific project requirements and approved welding procedures. We recommend discussing your classification requirements with our team.

What nitrogen consumption should I expect for thick-plate cutting?

Nitrogen consumption for 30-50mm plate cutting at 30 bar can be significant. We recommend pairing the machine with Xinhong's PSA nitrogen generator (99.9% purity, 10-80 m³/h) for on-site production, which typically pays for itself in 6-12 months compared to bottled nitrogen.

What support is available for shipyard installation?

Technical documentation, operation manuals, remote troubleshooting, and operator training are included. Xinhong provides installation guidance and commissioning support for shipyard environments. Contact us for service terms in your region.
