Laser cleaning machine enter the high-power era: Analysis of differences between 6000W and 3000W devices

In November 2024, when the 6000W handheld laser rust remover made its official debut, the entire industry was shocked. This device broke through the 3000W power ceiling for handheld models in one fell swoop, turning high-power laser rust removal from something exclusive to robotic arms into a "sharp tool in the hand" that can be flexibly operated.

Generational Leap in Core Performance

Although both devices share a laser wavelength of 1080nm, they show significant differences in energy conduction. The 3000W model comes standard with a 50μm fiber core diameter, while the 6000W model offers two options: 50μm and 100μm. This design difference holds hidden secrets: a larger core diameter results in a wider laser spot and more uniform energy distribution, doubling the efficiency when dealing with large areas of floating rust; on the other hand, a smaller core diameter is suitable for treating deeper rust layers, enabling precise stripping.

In terms of operational capability, the scanning width of the 6000W model has been expanded to 50 centimeters, an increase of nearly 70% compared to the 3000W model. Coupled with a default focal length of 1500mm, it can still maintain strong energy at an operating distance of 1.5 meters, greatly reducing the operational difficulty for complex workpieces. However, the power upgrade has also brought about a change in weight. Its gun head has increased to 2.2 kilograms, nearly three times that of the 3000W model (0.8 kilograms), which places higher physical demands on users during long-term operations.

The Art of Balancing Efficiency and Energy Consumption

Numbers tell the clearest story: The 3000W model can handle approximately 50 square meters of floating rust per hour, consuming 10 kWh of electricity; the 6000W model, on the other hand, boosts efficiency to 100 square meters per hour, with power consumption increasing proportionally to 20 kWh. This "doubling" phenomenon perfectly illustrates the law of conservation of energy — the total energy required to remove a given amount of rust remains constant, and high-power models significantly shorten the working cycle by increasing output per unit time.

In fact, this isn't unique to these two models. For continuous laser rust removers ranging from 1500W to 6000W, the core difference has always centered on efficiency. The 1500W model processes 25 square meters per hour, the 3000W reaches 50 square meters, and the 6000W exceeds 100 square meters, clearly showing a proportional relationship between power and efficiency. To put it simply, for the same workpiece, the 1500W model may need 4 scans to clean it, the 3000W only needs 2 scans, while the 6000W gets the job done in one go.

Behind this power upgrade lies the industry's unremitting pursuit of efficient operations. The emergence of the 6000W model undoubtedly provides a new solution for rust removal needs involving large areas and high timeliness, and further expands the application boundaries of laser rust removal technology.
