Plasma Hardfacing Machine

Deewi Automation: Your Premier Manufacturer, Supplier, and Exporter of High-Quality Plasma Hardfacing Machines. Our equipment can significantly improve the wear resistance, corrosion resistance and service life of the workpiece through precision plasma cladding technology.

Plasma Hardfacing Machine(PTA)

The Plasma Hardfacing Machine process utilizes a plasma arc as the heat source to melt, blend, and solidify alloy powder with the surface of the base metal. This process creates a high-performance alloy protective layer, reinforcing and hardening the surface of components. Unlike the physical bond in thermal spray coatings, the metallurgical bond between the Plasma Hardfacing Machine layer and the substrate is more stable, resulting in a denser and stronger wear-resistant hardfacing layer. In comparison to other welding techniques, Plasma Hardfacing Machine welding equipment is straightforward and easily automated. It offers excellent control precision, ensuring stable and reliable welding quality. Additionally, by adjusting the welding current, it can accommodate parts of various sizes and thicknesses. Plasma Hardfacing Machine technology is frequently used to repair damaged equipment components. If you are interested in this technology, we welcome you to discuss it further with us.

Plasma Transferred Arc (PTA) Hardfacing Process

The Plasma Hardfacing Machines process offers several advantages: low equipment costs, easy control of penetration depth, and fast deposition speed, leading to high production efficiency. The resulting hard-facing layer is aesthetically pleasing, has low dilution, and the process lends itself well to mechanization and automation. With the rapid development of automation control technology, an increasing number of Plasma Hardfacing Machines are adopting CNC (Computer Numerical Control) systems. This advancement enables precise control over parameters such as arc pressure, current, powder feed rate, oscillation amplitude, and frequency. Additionally, the CNC system of the hard-facing system allows accurate control of the torch’s travel speed and workpiece movement parameters. By adjusting hard-facing parameters, we can control the thickness, width, and hardness of the hard-facing layer.
In modern industry, Plasma Hardfacing Machines technology has become widely used. It is applied in various fields, including extruder screws, valve components, engine valve seats, cutting tools (milling cutters, lathe tools, etc.), diverse moulds, agricultural machinery, and accessories used in mining, shipping, power generation, and the petroleum industry, such as drill bits for crushing, grinding, or excavation.

The composition of the Plasma Hardfacing Machine.

The exact structure and design of plasma Hardfacing machines vary depending on the manufacturer and specific application requirements. With continuous technological advancements, their designs have become increasingly diverse. They might be portable plasma Hardfacing machines or stationary ones specifically designed for heavy-duty industrial applications. The commonly used components of plasma Hardfacing machines include:

Power Source
Gas Supply
Fixtures
Welding Positioner
Welding table
Process Control Panel
Powder Feeder
Column & Boom & Robot
PTA Torch
Water Chiller or Recirculator

At the heart of the plasma arc welding machine is the power source. This is typically a high-frequency inverter capable of supplying the necessary current and voltage to the plasma arc. It serves as the primary energy source for generating the plasma arc.

This is the main component where the high-temperature plasma arc process takes place. It typically consists of the torch body, electrode, and nozzle. By adjusting the power source’s parameters, we can control the intensity of the plasma arc.

The plasma arc welding process requires shielding gases, such as argon or nitrogen, to protect the welding area and stabilize the arc.

The welding material, usually in powder form, is delivered to the plasma arc via the powder feeder. The powder is melted to form the weld overlay.

To keep the workpiece in place during the process, it’s held by a combination of stands and clamps. This setup ensures that the workpiece remains stable, and it can also move according to a predetermined path. These stands and clamps come in various designs to accommodate different shapes and sizes of components.

Most welding equipment comes with a control system. Operators can adjust and control various parameters such as gas flow rate, powder feed rate, plasma arc current, voltage, and speed. This ensures precise and consistent welding results. Through the visualization panel, operators can also monitor the welding status of the workpiece in real-time.

Given the intense heat produced during plasma arc welding, a cooling system (usually water-cooled) is employed to prevent overheating of components like the torch or power source, maintaining them at a safe temperature.

Given the potential for harmful fumes during the process, equipping the machine with an exhaust or filtration system can sometimes be essential.

Safety features equipped in plasma arc welding machines protect operators from potential hazards, such as electric shocks or exposure to the hot plasma.
