Explore our premium product solutions optimized for heavy duty wear resistance and high-precision welding automation.
A comprehensive analysis of multi-process welding technologies in high-stress industrial applications.
In modern industrial manufacturing, the phrase "Wielofunkcyjna Maszyna Spawalnicza" (Multifunctional Welding Machine) represents far more than simple multi-process power supplies. It designates highly integrated, computerized industrial stations capable of executing high-precision jointing, automated PTA (Plasma Transferred Arc) hardfacing, and laser metal deposition. Industrial operations are constantly challenged to increase operating life while decreasing maintenance overhead. Specialized components in aerospace, heavy casting, and petrochemical refining demand distinct mechanical properties that conventional single-method welding systems cannot deliver cost-effectively.
By merging several functions—such as S-TIG welding, automated plasma powder cladding, and advanced laser surface treatment—into a singular automated motion platform, modern production plants achieve unprecedented flexibility. This integration significantly minimizes work-in-progress inventory, mitigates heat-affected zone (HAZ) damage, and ensures complete metallurgical bonding. The adoption of smart PLC programs paired with multi-axis robotic joints guarantees that even complex profiles like valve seats, hydraulic cylinders, and drilling screws receive precise overlay parameters.
At present, our 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.
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. Our dedication to hardfacing technology has driven us to establish state-of-the-art labs focused on alloy design, automated robotics control, and customized industrial integrations.
We develop complete production frameworks tailored to the exacting wear-resistance needs of heavy equipment manufacturers. Whether it's developing custom cutting-picks laser systems or engineering specialized internal-bore plasma cladding torches, our machinery offers unmatched longevity, stable arc ignition, and consistent deposit profiles.
Read More About Our JourneyI 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.
To reduce wear under high-stress operating environments, controlling the dilution rate of the weld bead is paramount. When cladding expensive cobalt-based alloys (Stellite) or tungsten carbides onto carbon steel substrates, conventional MIG or standard TIG welding mixes too much parent material into the clad layer, compromising its properties. Our technical team has engineered an optimized closed-loop controller that regulates heat inputs down to the microsecond. By implementing synchronized pulse currents and multi-axis mechanical feeding systems, our machines consistently keep dilution levels below 5% while ensuring robust metallurgical bonding.
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.
