The cladding alloy layer has metallurgical bonding with the workpiece substrate, resulting in high bonding strength.
The dilution rate of plasma arc surfacing can be controlled within 5% - 10%, or less.
It is easy to realize mechanization and automation throughout the surfacing process.
It can directly carry out plasma surfacing on the surface of corroded and greasy metal parts without complicated pretreatment processes.
Compared with other plasma spray welding equipment, it features a simpler structure, energy saving, and easy operation and maintenance.
The plasma arc provides high temperature, concentrated energy, good stability, and small residual stress and deformation on the workpiece.
Excellent controllability. The parameters of plasma arc (atmosphere, temperature) can be adjusted by changing power, gas type, flow rate, and nozzle size for efficient production.
Wide range of materials. Hardfacing alloy powder is not limited by casting, rolling, or wire drawing. It is especially suitable for hard wear-resistant alloys that are easy to powder but difficult to draw.

At present, most of the plasma powder stack welding machines in the market are high-power, which is due to the problem of plasma power supply to a certain extent. The structure of high-power plasma stack welding machines is mainly composed of two large and small power argon arc welding machines, with small power argon arc welding guiding the main arc and high-power argon arc welding guiding the main arc. This system overcomes the above problems by using a pure plasma power supply system that offers small size, light weight, and suitability for any working environment.
Most plasma stack welding guns on the market employ an external powder feeding system, and the handles are made of common materials. This configuration easily leads to powder blockage or electric leakage, threatening production continuity and operator safety. The optimized system features a built-in powder feeding design with a handle made of high-insulation polyethylene material, preventing common operational faults even under full machine load.
Standard machines in the market generally rely on scraper-type powder feeders. This method often results in uneven powder delivery and frequent blockages. By utilizing an advanced impeller-type powder feeding mechanism, our solution accurately controls the size and speed of the powder supply, eliminating feeding irregularities and blockages.
Plasma powder surfacing is an advanced surface modification technique that uses a high-temperature plasma arc to rapidly melt alloy powder and the substrate surface. As the heat source moves away, the mixed materials solidify into a high-performance metallurgical layer that strengthens and hardens the workpiece.
By precisely adjusting the plasma arc parameters (such as energy density, gas flow, and traverse speed), the dilution rate can be successfully controlled within a low range of 5% to 10% (or even less). This ensures that the properties of the surfacing alloy remain unaffected by the substrate.
Yes. One of the core benefits of plasma surfacing is its ability to be applied directly to the surface of corroded, greasy, or dirty metal parts without requiring complex, time-consuming chemical or mechanical pre-treatments.
Scraper-type powder feeders often cause uneven flow or complete blockages. The advanced impeller design utilizes motor direct drive to deliver powder uniformly and precisely controls both feeding speed and quantity to ensure smooth, continuous welding operations.
Unlike standard torches that use external feeding tubes and basic handle structures, this welding torch features an integrated die-casting body, a built-in powder feeding path, and a high-grade polyethylene insulation handle to completely eliminate electric leakage risks and powder blockages.
It features a dedicated 2000W active air conditioning refrigeration system with a 1/2 HP Panasonic compressor, R22 refrigerant, and an EBM fan from Germany. Its internal 8.5L water storage tank is made of corrosion-resistant 304 stainless steel to maintain optimal temperatures during long operations.
