Surface preparation prior to ship coating is directly related to hull corrosion resistance, appearance quality, and service life. For a long time, shipyards have relied on manual sandblasting and grinding for rust removal, processes plagued by high dust levels, noise, intense labor, and high cleaning costs. The industry urgently needs more environmentally friendly and efficient alternatives.
The core advantage of this newly released "Double-High" pulsed laser cleaning equipment lies in the combination of "High Power" and "High Pulse." Compared to traditional continuous wave (CW) lasers, nanosecond pulsed lasers do not generate sustained high temperatures during rust and paint removal, helping to reduce the risk of thermal damage to the substrate. Meanwhile, high-power models can cover larger working areas, improving cleaning efficiency for complex areas such as ship sections, decks, outer plates, and weld grooves.
The product matrix covers various scenarios:
Handheld Devices (Hundreds of Watts): Suitable for localized cleaning in confined spaces such as cabins, corners, and outfitting parts.
3kW AGV Intelligent Cleaning Robot: Ideal for automated operations in relatively regular areas like warehouses, decks, and planar sections.
4kW Wall-Climbing Robot Laser Cleaning System: Designed for high-difficulty conditions such as ship outer plates, large curved surfaces, and vertical walls.
The launch event featured live demonstrations of the 500W handheld cleaner, the 3kW intelligent robot, and the 4kW wall-climbing robot cleaning ship sections. The equipment operated stably, and the cleaning results were well-received by on-site experts.
Significantly, the group standard "Technical Requirements for Laser Cleaning Before Ship Coating," promoted by GSI and industry partners, officially came into effect on August 1, 2026 (Standard No. T/CANSI 20003-2026). This standard specifies operational procedures, parameter selection, post-cleaning surface protection, quality control, and acceptance criteria, helping to enhance the standardization and inspectability of laser cleaning in ship surface preparation.
From the perspective of overseas market demand, high-power pulsed laser cleaning, wall-climbing robot derusting, AGV automated cleaning, and upgrades to ship coating surface preparation are key areas of interest for shipbuilding, offshore engineering, structural steel maintenance, and ship repair enterprises. Future content can explore angles such as "4kW Pulsed Laser vs. Continuous Laser," "Applications of Wall-Climbing Robots in Hull Cleaning," and "How Laser Cleaning Meets Sa2.5 Standards for Coating Preparation" to attract international clients.
