Explore our elite configurations of precision laser cladding, PTA hardfacing, and robotic surface conditioning equipment
In contemporary heavy manufacturing, surface degradation caused by rust, oxidation, and abrasive wear remains one of the largest vectors of unscheduled downtime and component retirement. Globally recognized as the modern gold standard of surface preparation, Laser Rimuovi Ruggine (Laser Rust Removal) systems utilize high-frequency, short-pulsed laser light to ablate contaminants without inducing thermal stress or mechanical deformation in the underlying substrate.
From European aerospace facilities conforming to strict environmental regulations to heavy infrastructure sites in North America, industrial entities are rapidly transitioning away from abrasive sandblasting, chemical etching, and manual scouring. The mechanics of pulsed fiber laser cleaning provide a zero-emission, contact-free solution that vaporizes metal oxides within microseconds. By adjusting laser fluence, repetition rate, and beam profile, operators can target rust layers down to the micron level with unmatched precision.
As a prominent OEM/ODM global supplier, Shanghai Duomu integrates this surface treatment capability with advanced metallurgical restoration processes—such as Laser Cladding and Plasma Transferred Arc (PTA) hardfacing—to deliver a comprehensive lifecycle defense for critical industrial components.
Maximizing component lifetimes by pairing advanced cleaning with state-of-the-art additive resurfacing
By tuning the laser's peak power density, our systems achieve rapid sublimation of iron oxides without crossing the damage threshold of the base metal. This ensures zero micro-cracking and maintains the structural integrity of aerospace alloy components.
In Plasma Transferred Arc (PTA) and Laser Cladding, control of the dilution rate is paramount. Minimal dilution ensures that the deposited hardfacing layer retains its pure chemical composition and wear-resistant properties, free from contamination by the substrate metal.
Integrating cleaning laser heads and cladding torches with 6-axis articulated robots allows for the seamless treatment of complex geometries, such as pump impellers, oil stabilizers, and turbine blades.
