    CPL-10000- RW/GW Medium-Thickness Steel Autogenous Laser Welding System

    Robotic welding system for the autogenous welding of thin to medium-thickness steel of up to 20mm

    CPL-10000-RW/GW medium-thickness steel autogenous laser welding system is built around a 10kW-class full-vector optical field-controlled fiber laser. It integrates a "5-in-1" in-weld monitoring sensor and a real-time laser welding control platform. With modular and configurable laser welding software, the system is capable of handling complex working conditions, solving key challenges in medium-thickness plate laser welding—such as alignment tolerance and welding defects. It enhances welding quality, effectively mitigates common defects like pores, cracks, and undercutting, and improves weld strength and fatigue life.

    Features
    • Superior weld quality
      Experience exceptional weld quality and a smooth, uniform finish. By leveraging the high-speed dynamic beam of our full-vector optical field-controlled laser, the autogenous laser welding system actively prevents common defects such as pores and cracks, significantly reducing the need for post-processing.
    • Increased efficiency
      The laser welding system's automatic adaptation to weld assembly tolerances allows you to complete single-sided, single-pass welding on metals from 5mm to 20mm thick. For example, you can achieve impressive welding speeds of up to 2m/min on 10mm-thick steel.
    • Extended fatigue life
      Boost the longevity and durability of your welds. The welding process offers a thermal efficiency that is twice that of conventional lasers, resulting in minimal damage to the base material and a significant extension of the weld's fatigue life—ensuring a greater return on your investment.
    • Cost savings
      Dramatically lower your operational costs. Our autogenous welding process eliminates the need for filler wire while still meeting required mechanical performance standards. This high-quality, consumable-free approach minimizes material waste, reduces rework, and significantly lowers your overall production costs.
    • Intelligent process monitoring
      The steel laser welding system provides comprehensive real-time oversight of the entire welding process. Equipped with multiple sensors, it continuously monitors critical parameters like power and speed. Its self-learning capabilities allow it to automatically adjust parameters to optimize quality and reduce the time spent on process debugging. Every weld is recorded in real-time for quick, post-weld quality checks.

    The laser's internal water-cooling air conditioner ensures stable operation, and the external optical path and welding head are sealed to guarantee normal function in temperatures up to 40°C. For dust, protective lenses and air knives provide isolation, so it is not a concern during normal use. However, for prolonged periods of disuse, the laser head should be protected to prevent dust from entering.

    The full-vector optical field-controlled laser, with its excellent beam quality, 10MHz switching frequency, and freely defined spot shape, is ideal for welding various materials. It provides a stable welding process and superior quality for highly reflective materials like purple copper, high-porosity die-cast aluminum, common carbon steel and stainless steel, as well as various combinations of dissimilar materials.

    The custom-defined spot range of the optical field-controlled laser can be up to 1mm, providing greater gap adaptability than conventional lasers within this defined spot range.

    Welding parameters are a critical factor in laser welding, and the process is relatively dynamic. CP Laser provides a multi-parameter dynamic monitoring and closed-loop control solution that ensures stable welding quality even with non-constant welding processes.

    The full-vector optical field-controlled laser's customizable spot shape and 10MHz switching frequency enable high-speed switching in the longitudinal direction of the spot. This optimizes the melt pool's flow field distribution, reducing the occurrence of defects like pores, cracks, and spatter.

    Consumables in the laser welding process include protective lenses, shielding gas for the melt pool, and circulating cooling water for the laser and welding head. The cooling water is replaced approximately every three months, and the shielding gas consumption is lower than traditional welding methods like TIG welding (per meter of weld length). The overall consumable cost is low. With a suitable process, optical path design, and maintenance, protective lenses can last for several weeks, making their relative cost very low.

    By using multi-sensor real-time monitoring of the welding process, our closed-loop inference system analyzes how process parameters affect welding outcomes. This optimizes the R&D process for adjusting welding parameters. What was once an experience-based process can now be transformed into a machine learning approach driven by neural network inference, significantly enhancing process R&D capabilities and efficiency.
