Explore our elite inventory of cutting-edge welding machines, plasma torches, and industrial cladding systems.
In modern industrial manufacturing, 클래딩 용접 (Cladding Welding / Surface Hardfacing) has transitioned from a basic maintenance procedure into a cornerstone technology for extending equipment lifespan, maximizing operational uptime, and reducing total lifecycle costs. Across heavy industries worldwide—ranging from aerospace and petrochemical refineries to advanced metallurgy and power generation—components are continuously subjected to extreme operational stresses, including high-pressure environments, corrosive media, thermal cycling, and aggressive abrasive wear.
Traditional welding methods often introduced excessive heat input, leading to substrate dilution, micro-cracking, and mechanical distortion. However, the advent of advanced automated systems such as Plasma Transferred Arc (PTA) welding and high-power Laser Cladding Systems has completely revolutionized the sector. These technologies enable precise metallurgical bonding between substrate materials and high-performance alloy powders (such as Stellite, nickel-based superalloys, and tungsten carbide composites), ensuring supreme wear resistance without compromising the structural integrity of the base metal.
Driven by global initiatives toward sustainable manufacturing and industrial remanufacturing, the demand for high-precision cladding equipment has accelerated exponentially. Enterprises are actively seeking turnkey solutions that incorporate smart automation, real-time closed-loop monitoring, and multi-axis robotic integration. Shanghai Duomu has positioned itself at the forefront of this global transformation, delivering robust, high-stability PTA and laser cladding systems engineered for rigorous industrial demands.
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.

Expert insights and authoritative answers regarding cladding welding technologies, parameters, and applications.
Cladding welding is a surface modification technique where a layer of corrosion-resistant or wear-resistant alloy is metallurgically bonded to a cheaper or tougher base metal substrate. Processes like PTA (Plasma Transferred Arc) and Laser Cladding utilize thermal energy to melt alloy powder or wire onto the substrate with minimal dilution.
While Laser Cladding offers ultra-high precision and minimal heat-affected zones (ideal for intricate geometries and thin-walled parts), PTA Cladding provides higher deposition rates, lower equipment investment costs, and excellent penetration control, making it exceptionally suited for large-scale industrial components such as valves, rollers, and hydraulic rods.
Heavy industries including oil and gas, petrochemical refining, mining, power generation, aerospace, and agricultural machinery manufacturing rely heavily on automated cladding to protect critical components from premature failure caused by extreme wear and corrosion.
Shanghai Duomu leverages over a decade of specialized R&D and manufacturing experience, utilizing rigorous quality control protocols, advanced CNC controls, and independently developed plasma torches and powder feeders to guarantee high stability, precision, and long-term operational reliability.
