Lihe Laser 6kW Laser Cleaning Machine: Overseas Heavy-Duty Industrial Application Case
In global industrial scenarios such as shipbuilding, port equipment, heavy steel structures, and automotive component manufacturing, traditional methods like sandblasting and chemical cleaning suffer from high pollution, low efficiency, and substrate damage. With high power, high efficiency, no consumables, and eco-friendly safety, Lihe Laser's 6kW continuous-wave fiber laser cleaning machine has been successfully adopted in Europe, America, Southeast Asia and other overseas markets, providing stable and reliable surface treatment solutions for industrial customers worldwide.
Project Background
A major overseas ship repair and steel structure manufacturer faced long-standing challenges in cleaning thick rust, old coatings, and oxide layers on hulls, decks, and large structural parts. Traditional cleaning was time-consuming, costly in environmental compliance, and prone to substrate thinning and deformation. The customer urgently needed a high-power, large-area, green and efficient industrial cleaning system to improve operational efficiency and meet local environmental regulations.
Solution
Lihe Laser provided the customer with our 6kW continuous-wave fiber laser cleaning machine, optimized for ship and heavy steel structure applications with adjustable spot size, scan width and travel speed. It delivers:
Fast removal of thick rust, multi-layer paint, scale and salt-spray corrosion
No abrasives, no chemicals, zero waste water and residue, compliant with EU environmental standards
Non-damaging to base material, preserving dimensional accuracy and structural integrity
Handheld and automation-ready for large-area continuous operation
Outcomes
Significantly improved cleaning efficiency: covers large steel structures per hour, greatly shortens project duration
Lower operating costs: reduces expenses on consumables, waste disposal and environmental treatment
Uniform surface quality: provides an ideal pre-treatment interface for welding and coating
Safer working environment: dust-free, low heat risk, compliant with occupational health standards
Customer Feedback
The customer confirmed that Lihe Laser 6kW laser cleaning machine fully meets heavy-duty continuous industrial requirements. The equipment is stable, easy to operate, and low in maintenance, effectively enhancing corporate competitiveness and environmental compliance.
