The following is an introduction to the selection of laser cladding materials from high-speed laser cladding machine manufacturers.

　　 High-speed laser cladding machine The manufacturer will introduce the selection of laser cladding materials below.

　　High-speed laser cladding machine manufacturer: How to choose laser cladding materials?

　　Laser cladding materials refer to materials used to form cladding layers. According to their shape, they are divided into alloy powders (powder materials), wire materials, sheet materials, etc. Among them, powdered cladding materials are widely used. The selection of cladding materials directly affects the service performance of the laser cladding layer and the processability of laser cladding.

　　 High-speed laser cladding machine Material Selection Precautions

　　Selecting suitable cladding materials is the key to obtaining cladding layers with good surface and internal quality and performance that meet the requirements of use.

　　1. Excellent usability

　　The selected material needs to meet the requirements of the part surface state, such as wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, conductivity, etc.

　　2. Excellent chemical stability and thermal stability

　　If the coefficient of thermal expansion is too different from that of the substrate, the rapid heating and cooling during laser welding will cause uneven shrinkage, resulting in large thermal stress, causing the coating to peel off or crack from the substrate.

　　4. Good wettability

　　It should have good wettability with the substrate in the molten or semi-molten state to ensure good bonding performance between the coating and the substrate.

　　5. Relatively good fluidity

　　When the coating material is powder, its shape, particle size distribution, and surface state meet the requirements. Good fluidity is required to obtain a good coating. When the coating material is a rod or wire material, it has good forming performance and a certain strength, and the particle size is also uniform and accurate, and the surface is clean and pollution-free.

　　The metal powders used for the guide plate laser cladding machine are mainly tool steel, martensitic steel, stainless steel, pure titanium and titanium alloys, magnesium aluminum alloys, nickel-based alloys, copper-based alloys, cobalt-chromium alloys, etc. Among the laser cladding materials, nickel-based self-fluxing alloy powders, which are widely studied and applied, have good wettability, wear resistance, and high-temperature self-lubricating properties. Different chemical compositions and types of nickel-based powders can be selected according to the wear resistance requirements. Laser cladding manufacturing nickel-based cladding layers are widely used in molds, cast iron, nickel alloys, steel, stainless steel parts, and crankshafts, rolls, bushings, bearing housings, eccentric wheels, and other parts.

　　Benefits of high-speed laser cladding machine repair roll surface

　　1. Photocladding is currently more advantageous than traditional laser cladding repair in the entire mechanical repair industry. It is automated repair aimed at computer-aided automatic repair, simple and easy to use, with good repair effect and high hardness, saving a lot of manpower and material resources.

　　2. Photowelding is suitable for the repair of large motor rotors, wind power and hydropower motor rotors, and other mining equipment, nuclear power equipment, military and aerospace development fields. It can repair various crankshafts, straight shafts, and valuable parts, both domestic and imported.

　　3. AG pulsed laser, low heat generation, no deformation during repair, can also be used for repair, cladding, and surface quenching treatment of roll surfaces, valves, cutting teeth, coal mills, roll surface wear-resistant treatment, oil drilling rigs, screws, and valves.
