Direct manufacturer solutions specializing in PTA cladding, automated laser systems, and custom welding positioners engineered for industrial performance.
Modern industrial components are subjected to extreme wear, severe high-temperature erosion, and corrosive chemical attacks. Under such conditions, traditional welding methodologies fall short. Nahtschweißen (seam welding) integrated with modern **Plasma Transferred Arc (PTA) cladding** and **Laser Cladding** systems has emerged as the definitive path for surface modification and wear reduction.
By establishing a highly precise metallurgical bond between the base substrate and the alloyed cladding powder, our technology achieves negligible dilution rates and highly refined microstructures. We offer global buyers a robust combination of metallurgical stability, structural strength, and customized alloy compositions to significantly extend equipment lifespans.
From automated robotic setups in automated aerospace assembly lines to deep-hole welding tools for downhole extraction, our industrial solutions deliver maximum reliability under intense operation cycles.
At present, Shanghai Duomu'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.
Our solutions prevent soil-contact wear and enhance the surface hardness of tillers, plowshares, and harvester components with economical PTA cladding.
High-precision automated robotic systems enable seamless welding of turbine components and lightweight alloys, ensuring maximum safety under stress.
We supply corrosion-resistant cladding systems for drill pipes, valve gates, mud pumps, and hydraulic rods operating in extreme downhole conditions.
Heavy duty cladding systems for continuous casting rolls, forging dies, and hot rolling guides that must resist thermal fatigue and abrasion.
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. We coordinate research, manufacturing, engineering, and aftersales services to deliver advanced wear-resistant and repair solutions globally.
Through robust internal quality protocols and ongoing technological investments, our engineering team ensures that every automated PTA cladding workstation, portable EDM cladding repair machine, and multi-axis welding manipulator leaving our facilities meets the highest criteria of industrial stability and long-term durability.
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.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements, including special equipment in the industry, such as hydraulic rod cladding machine, pick cladding machine, valve cladding machine, etc.
Global procurement managers face the constant challenge of minimizing total cost of ownership (TCO) while meeting rigorous quality standards. The selection of reliable Nahtschweißen and cladding manufacturers represents a critical strategic decision. Buyers are shifting away from manual overlay practices to automated systems that guarantee consistent coating properties and higher deposition rates.
Shanghai Duomu provides end-to-end support for international projects. We help plant engineers and sourcing managers establish standardized workflows for:
Our engineers configure turnkey cladding solutions tailored to target geometries, load profiles, and chemical environments:
As manufacturing shifts towards Industry 4.0, our technological development focuses on smart integration, closed-loop process monitoring, and multi-metal additive manufacturing.
Integrating real-time thermal camera systems to dynamically regulate power output, guaranteeing uniform bead formation and eliminating internal voids or porosity.
Combining the cost-efficiency and high deposition rate of Plasma Transferred Arc with the minimal heat input and high speed of laser cladding systems.
Expanding the motion control coordinates with custom-built 6-axis and 8-axis robot configurations to weld complex non-rotational structures.
To support global supply chains, Shanghai Duomu implements a comprehensive international support program. We ensure that our equipment aligns with target country electrical regulations (such as CE, UL, or CSA standards). Additionally, we provide localized commissioning services, on-site personnel training, and a rapid-response spare parts logistics network to prevent unplanned production stoppages.
Direct answers to technical queries frequently raised by metallurgists, procurement specialists, and operations managers.
While both PTA and laser cladding establish a metallurgical bond with the base substrate, laser cladding utilizes a focused laser beam resulting in lower heat input, minimal distortion, and a highly narrow heat-affected zone (HAZ). PTA cladding uses a plasma arc, offering significantly higher deposition rates and lower equipment and maintenance costs, making it ideal for thicker wear-resistant coatings.
Dilution rate measures the mixing of the base metal into the deposited alloy coating. High dilution levels dilute the protective properties of the cobalt, nickel, or carbide alloy. Shanghai Duomu systems are engineered with precision powder feed and arc controls to maintain dilution rates below 5%, ensuring the target surface alloy maintains its designed hardness, corrosion, and wear resistance.
Yes, we specialize in customizing equipment profiles. Through our Technical Department, we develop specialized multi-axis CNC positioners, custom welding torches for internal pipe coatings, and automated robotic systems specifically designed for unique components like ball valves or irregular screw flights.
