Industrial grade custom precision welding machinery developed for high-deposition hardfacing and precision additive manufacturing.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machine and Laser cladding machine for more than ten years with a strong technical background. As industrial components undergo extreme mechanical friction, erosion, corrosion, and high thermal demands, standard materials fail. By depositing customized superalloy overlays—such as Cobalt, Nickel, and Iron-based alloys—using Plasma Transferred Arc (PTA) systems, we help global enterprises multiply component lifespans by up to 300% to 500%.
Our engineering expertise lies in controlling the dilution rate of the overlay layer while maintaining high deposition rates. Lower dilution rates translate directly into higher metallurgical purity of the top clad layer, yielding exceptional resistance properties. Discover how Duomu combines automated motion control, robust thermal monitoring, and customized powder feeders to deliver industry-certified weld overlays.
Developing structural architectures that combine intelligence, automation, and real-time process monitoring.
As smart manufacturing evolves, Shanghai Duomu is leading the way in integrating closed-loop control systems. Our R&D focuses on several major trends that will define the future of hardfacing:
Real-time seam finding and weld path compensation using vision sensors to adapt to component dimension inconsistencies. Ensures stable bead overlap and uniform height profile.
Configured powder feeders capable of injecting variable ratios of Tungsten Carbide (WC) and Ni-based powders in real-time, matching hardness profiles dynamically.
Combining the absolute precision and narrow heat-affected zone (HAZ) of laser cladding with the high deposition speed and low setup cost of PTA.
I have an independent R&D team, which develops, produces and sells plasma cladding machine equipment. The welding machine has stable performance and can maintain efficient long-term operation. In addition, the laser cladding equipment sold by the company can effectively support large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions.
At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, etc.
How Shanghai Duomu ensures reliable lead times, absolute component consistency, and cost-effective shipping global pathways.
Located in the heart of East China's manufacturing cluster, Shanghai Duomu draws upon a world-class localized industrial ecosystem. From advanced raw raw metal powders (Cobalt base, Nickel base, Tungsten Carbide) to high-precision optical parts and electrical panels, we procure components with high quality controls and zero delay. Our integrated supply chain management guarantees that every custom PTA cladding machine, automatic gantry welder, or CNC laser cladding system undergoes rigorous quality audits prior to dispatch.
Furthermore, because our manufacturing plant maintains direct partnerships with premium cargo carriers and bulk logistics channels, we provide comprehensive delivery, customs clearance assistance, and local compliance support globally. Our customer service engineers can assist in machine integration, testing protocols, and training programs remotely or via local hub support agents.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements.

Answers to crucial industrial questions related to Plasma Transferred Arc Welding and Laser Cladding capabilities.
PTA (Plasma Transferred Arc) uses a highly concentrated plasma arc to melt alloy powder and a minimal top layer of the substrate. This results in significantly lower dilution rates (often under 5-10%), a narrower Heat Affected Zone (HAZ), higher deposition rates, and the ability to process hard-to-weld materials like Tungsten Carbides without excessive dissolution.
We analyze the shape of the component (e.g. ball valve, extruder screw, hydraulic rod) and design customized motion fixtures, robotic integrations, and plasma torches (external/internal bore cladding torches). The control system is then configured with custom welding programs to automate the cladding cycle.
Common materials include Cobalt-based alloys (Stellite equivalents for corrosion/erosion resistance at high temperatures), Nickel-based alloys (excellent for oxidation resistance and self-fluxing parameters), Iron-based alloys (cost-effective wear protection), and Tungsten Carbide matrices (extreme mechanical abrasion resistance).
Yes, all industrial machinery shipped by Shanghai Duomu is manufactured under ISO 9001 guidelines and complies with necessary CE electrical and mechanical safety directives. Standard ASME/welding certifications for cladding processes are fully supported.
We supply detailed step-by-step video setup guides, standard remote diagnostic assistance over secure HMI cloud channels, local maintenance parts warehouses, and can dispatch engineers for on-site commissioning and training programs upon request.
