Engineered solutions, torches, and automated welding lines designed to optimize dilution control and overlay integrity.
Industrial components in high-stress sectors face severe degradation from extreme sliding wear, impact abrasion, chemical corrosion, and elevated thermal cycles. Surface engineering—specifically Plasma Transferred Arc (PTA) cladding and Laser cladding—has transitioned from a basic maintenance technique to a critical phase of design engineering.
The engineering core of cladding lies in managing the dilution rate. Standard arc welding methods typically result in high dilution (10% to 25%), which shifts the chemistry of the deposited alloy and requires thick, multi-layer overlays to achieve specified hardness. In contrast, advanced systems leverage concentrated heat sources to restrict dilution under 5%, preserving raw overlay properties in a single pass.
By optimizing powder injection pathways and arc column density, modern tools allow manufacturers to deposit specialized matrix alloys (e.g., cobalt-based Stellites, nickel-based superalloys, and tungsten carbide metal matrix composites) with minimal thermal degradation of the host substrate. This metallurgy optimization extends component life up to 10 times compared to untreated parts.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years, supported by a strong technical background. The company operates a dedicated R&D division focused on the complex physics of plasma arcs and multi-axis CNC motion control.
Our independent technical department develops, produces, and sells plasma cladding machine equipment designed for long-term industrial reliability. With mature engineering processes, the company provides complete turnkey solutions for manufacturing plants and remanufacturing centers globally.
This includes tailored cladding solutions like hydraulic rod cladding machines, pick cladding tools, and valve seat hardfacing platforms. These specialized machines deliver consistent overlay quality while reducing manual operator input.
