6kW High Power Gantry Laser Welding Machine for Thick Plate
In the realm of heavy-duty industrial manufacturing, achieving high-quality and high-efficiency welding on thick plates has always been a core challenge. Our 6kW High Power Gantry Laser Welding Machine is engineered to conquer this very challenge. Specifically designed for welding medium to super-thick metal plates (such as carbon steel, stainless steel, aluminum alloys, etc.), it integrates exceptional weld penetration, unparalleled processing stability, and an intelligent operational experience. It is the ideal choice for industries like shipbuilding, pressure vessel manufacturing, steel structures, construction machinery, and energy equipment to achieve a dual leap in both production capacity and quality.
Core Selling Points
  • 6kW High-Power Fiber Laser for Superior Deep Penetration Welding Equipped with a high-performance 6kW continuous fiber laser, the machine concentrates energy to effortlessly achieve single-pass full-penetration welding on thick plates. Whether it's 20mm structural steel or thicker special alloys, it ensures welds possess extremely high strength and excellent internal quality, fundamentally meeting stringent structural integrity and airtightness requirements.
  • High-Rigidity Gantry Structure for Ultimate Stability Over Long Travels The machine adopts a high-arch gantry frame structure with stress-relief treatment, offering exceptional rigidity and stability. This design not only provides a vast processing space (X/Y/Z axis travel can be customized to easily cover ranges of several meters) but also ensures a repeat positioning accuracy of up to ±0.03mm during high-speed, long-distance welding. Even when processing multi-meter continuous welds, it effectively suppresses vibration, guaranteeing consistent weld penetration and preventing defects like lack of fusion or undercutting caused by mechanical deformation.
  • Intelligent Welding to Precisely Handle Complex Conditions The system can be configured with advanced CCD visual positioning and laser seam tracking systems. In actual production, workpieces inevitably have assembly deviations. This system captures the weld seam position in real-time and intelligently corrects the welding trajectory. It ensures the weld remains perfectly centered even with assembly errors of ±0.5mm, significantly reducing the precision requirements for fixtures and guaranteeing consistency and reliability in batch production.
  • Superior Weld Quality, Balancing Internal Strength and External Aesthetics Benefiting from the low heat input and small heat-affected zone (HAZ) of laser welding, workpiece deformation is minimal. Combined with a specialized oscillating welding head and coaxial gas shielding system, spatter is effectively reduced, yielding high-quality welds that are beautifully formed, oxidation-free, and without backside marks. Test data shows that workpieces welded with this equipment maintain a pass rate of over 99% in helium leak tests and high-pressure water tests, far superior to traditional TIG/MIG processes.
  • High-Efficiency Production for Maximized Equipment Utilization The machine supports an intelligent dual-station design. Two shuttle tables can be loaded and unloaded alternately while the central welding station operates continuously, achieving a near "zero-interval" production flow. This design minimizes equipment downtime, elevates production efficiency to a new level, and effectively breaks through production bottlenecks.
