weld overlay cladding process

Weld Overlay Machine

Welding covering machines can cover the surface of metal parts with one or more protective layers. To improve its wear resistance, and corrosion resistance, or to repair damaged workpiece surfaces.

plasma hardfacing

Plasma Hardfacing Machine

Plasma cladding machine is a device that uses plasma arc welding technology to apply a layer of wear-resistant, corrosion-resistant, or other characteristic materials on the surface of the workpiece.

Laser Cladding Machine

Laser cladding machine uses a laser to bond materials onto surfaces, creating a high-performance covering layer that enhances wear, and corrosion resistance, and repairs parts.

Micro Plasma Welding

Micro plasma arc welding machine is a precision welding technology that uses a small diameter plasma arc to achieve welding results. Suitable for welding thin sheet materials and small components.

Plasma Spray Systems

Plasma spraying system is a surface engineering technology that uses a plasma spray gun to apply coatings on the surface of materials to improve material properties or restore part dimensions.

Custom Built CNC Machines

Custom CNC machines are designed and built to specific manufacturing needs and specifications to suit a variety of specialized machining tasks. Covers industrial applications from basic to high-end.

Best Services

We will supply the solution machine with training video and user’s manual in English for installing, operation, maintenance and trouble-shooting, and shall give technical guide by Desktop remote, E-mail, Telephone, Mobile, Whatsapp, Skype, 24/7 online chat, and so on, when you meet some problem of installation, operation or adjusting.


Our products can provide you with more cost-effective options in many fields.

Wear Re sistant

Many industries face the problem of wear; whether it be manufacturing or mining. Mechanical wear causes the functional surface of machine components to degrade, eventually leading to total failure and machine breakdowns.

Corrosion Resistant

Corrosion is a chemical reaction in which metals transform into more chemically stable forms, Most often this occurs in machine components we they come into contact with water or corrosive chemicals. Corrosion resistant coatings create a surface barrier.

Plasma Cutting

Plasma is an effective means of cutting thin and thick materials alike. Handheld torches can usually cut up to 2 in (48mm) thick steel plate, and more powerful computer-controlled torches can pierce and cut steel up to 12 inches (300mm) thick.

Electrical Conductivity

Conductive coatings use thermal spray to apply metallic substances to surfaces to increase electrical conductivity or to guide electrical current away from other components, You can also thermal spray an insulating layer on the surface of conductive materials, which can significantly reduce your material costs.

Thermal Barrier

Thermal Barrier Coatings, most machine components experience mild heat from production but some required precise heat management. Thermal spray can create specially designed barriers to manage heat transfer on components. These coatings can decrease thermal conductivity, mitigate thermal expansion and resist thermal shock.

Complete Plant

We are also adept at providing comprehensive equipment solutions for welding, thermal spray, machine and assembly, offering you a one-stop service. Our products can be widely applied in the production of valve, medical guidewire, tunnel shield blade, ball valve, glass mould, rotary tiller blade, and other products.
