State-of-the-art automated equipment designed to optimize production and wear protection in UK infrastructure and manufacturing sectors.
London’s industrial sector is undergoing a rapid transition toward high-value advanced manufacturing and robust circular economy practices. As major infrastructure networks such as the London Underground, maritime ports along the Thames Estuary, and recycling facilities expand, the demand for wear-resistant materials has grown exponentially. Standard mechanical components are subject to extreme friction, high thermal stresses, and aggressive corrosive environments. Standard base metals, regardless of how well they are heat-treated, often fail to meet these demands.
Our Plasma Transferred Arc (PTA) welding and Laser Cladding systems provide metallurgical wear solutions that deposit high-performance alloys—including cobalt-based Stellite, nickel-based superalloys, and tungsten carbide matrices—directly onto vulnerable component surfaces. This specialized surface engineering dramatically extends the operational lifespan of industrial machinery, resulting in decreased downtime and lower total ownership costs for local businesses.
An engineering analysis comparing the two premier thermal surfacing technologies to assist in procurement decisions.
| Performance Metric | Plasma Transferred Arc (PTA) Hardfacing | High-Speed Laser Cladding |
|---|---|---|
| Dilution Rate | Low (Typically 5% – 10%) | Ultra-Low (Typically < 5%) |
| Deposition Rate | High (2 to 12 kg/hour depending on alloy) | Medium (1 to 4 kg/hour) |
| Bond Strength | Metallurgical (Fusion zone > 400 MPa) | Metallurgical (Minimal heat input interface) |
| Heat-Affected Zone (HAZ) | Moderate (Controlled heat distribution) | Minimal (Highly localized energy beam) |
| Cladding Material Variety | Powder & wire (Stellite, Tungsten Carbide, Nickel) | Mainly fine metal powders |
| Primary Applications | Extruder screws, heavy valves, mining picks | Hydraulic cylinder rods, high-precision shafts |
While Laser Cladding excels at applications requiring minimal thermal distortion and thin overlays, PTA Cladding remains the preferred heavy-duty option for thick, wear-resistant coatings. PTA systems are highly efficient for thick deposits because they maintain excellent deposition efficiency and robust bond integrity, making them well-suited for heavy industrial parts that face harsh, abrasive environments.
