Explore our elite lineup of high-precision micro-plasma, digital TIG, and automated laser cladding equipment designed to minimize dilution rates and heat-affected zones.
In contemporary heavy-industry engineering, traditional welding methods are no longer sufficient to combat the synergistic degradation of wear, high-load impact, and severe chemical corrosion. The transition to Soudure Au Tig (TIG Welding) and advanced metallurgical cladding processes—such as Plasma Transferred Arc (PTA) and High-Speed Laser Cladding—represents a major leap forward in component life-cycle extension and operational reliability.
TIG welding, known globally as Tungsten Inert Gas welding, provides the benchmark for precision and absolute aesthetic control. By decoupling the heat source from the filler material deposition, TIG enables deep fusion control, which is vital for thin-walled elements, heat exchanger diaphragms, and specialized alloy structures. When scaled up to automated PTA (Plasma Transferred Arc) cladding, the arc energy is mechanically and electro-magnetically compressed, producing a highly focused heat column capable of depositing robust wear-resistant overlays like tungsten carbides and nickel-based superalloys.
As a global pioneer in surface engineering, Shanghai Duomu has functioned as a premier manufacturer and exporter of PTA cladding and high-efficiency laser cladding systems for over a decade. Backed by solid research partnerships and a dedicated technical department, we own and operate a fully independent R&D pipeline that designs, manufactures, and commissions industrial fusion solutions globally.
Whether it is standard digital TIG welders or complex multi-axis CNC gantry cladding plants, our machinery is engineered to withstand long-term, high-duty-cycle industrial operations. We offer customizable configurations tailored to industry-specific requirements, including hydraulic rod overlay cladding systems, agricultural tillage pick hardfacing systems, and heavy-duty petrochemical valve seat protection systems.
Collaborate With Our ExpertsLeveraging advanced thermal dynamics and intelligent toolpath control, our systems bridge the gap between traditional manual TIG and state-of-the-art robotic metal additive manufacturing.
| Technology System | Key Heat & Deposition Characteristics | Average Dilution Rate | Primary Industrial Application |

| Digital High-Speed S-TIG | Decoupled wire feeding; arc stability control; optimized gas shielding shroud. | 5% – 8% | Heat exchanger diaphragms, pipe root passes, custom alloy fabrication. |
| Diode/Fiber Laser Cladding | Ultra-focused energy density; instantaneous metallurgical fusion; rapid cooling rates. | < 2% | Hydraulic cylinder shafts, turbine blades, extruder screw flights. |
| Robotic Hybrid Cladding | Integrated multi-axis toolpathing; dynamic powder feeding; real-time infrared temperature control. | 1% – 3% | Large-scale casting repairs, tooling rebuilds, mining pick hardfacing. |
Our custom-developed welding, PTA, and laser cladding machinery plays a vital role across multiple critical heavy industries:
Extending the service lifespan of tillage tillers, plowshares, and subsoiler teeth using cobalt and iron-based PTA overlay coatings.
High-precision repair of turbine blades, compressor discs, and critical high-strength titanium or superalloy structures.
Anti-wear and corrosion-resistant overlays for ball valves, drill stems, and blowout preventers operating in sour service environments.
In-situ remanufacturing of heavy continuous casting rollers, forging dies, and hot extrusion tooling subject to thermal fatigue.
Partnering with a leading China-based OEM/ODM manufacturer like Shanghai Duomu provides distinct strategic benefits for global integrators, distributors, and heavy-industry end users:
Step 1: Collaborative Custom R&D Design
Step 2: In-house CNC Machining & System Assembly
Step 3: Rigorous 72-Hour Load and Continuous Weld Testing
Step 4: Secure Export Packaging & Fast Freight Logistics
Discover how Shanghai Duomu's advanced PTA hardfacing and laser cladding systems help heavy industries reduce downtime and extend product lifespans.
"The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, high corrosion, and high-temperature erosion working conditions, but also a key path to improving product competitiveness. Implementing Duomu's PTA system has reduced our scrap rates by over 15%."
"In industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. However, maintenance data shows that they are among the most frequent causes of unplanned production downtime. Using automated cladding on screw flights has tripled our uptime."
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate. Shanghai Duomu machines consistently maintain rates below 4%."
