Introduction of laser cladding

       

Wococarbide provides technical supports and laser cladding powder. Many people look up the dictionary and still don't know what laser cladding means. In short, laser cladding is to repair the damaged spare parts, so as to repair the machine at low cost and prolong the service life of the machine.

Application of laser cladding

Laser cladding is mainly used in three aspects: surface modification, surface repair and laser additive manufacturing.

First,  Surface modification of materials, such as gas turbine blades, rolls, gears, etc;

Second,  Repair the surface of products, such as rotor, mold, etc.

Third,  Laser additive manufacturing. By means of synchronous powder or wire feeding, the laser cladding layer by layer is carried out, and then the parts with three-dimensional structure are obtained. This technology can also be called laser melting deposition, laser metal deposition, laser direct melting deposition and so on.

 

Advantages of laser cladding

1. Low cost. Compared with the new machine and equipment, the laser cladding method can prolong the service life of the machine, effectively solve the problem of replacing parts, and save a lot of money for the company.

The strength of the repaired parts can reach more than 90% of the original strength, and the repair cost is less than 1 / 5 of the replacement price. What's more, it shortens the maintenance time and solves the problem of rapid repair of rotating parts that must be solved for the continuous and reliable operation of major complete sets of equipment in large enterprises. In addition, laser cladding of super wear-resistant and anti-corrosion alloy on the surface of key parts can greatly improve the service life of parts without deformation; Laser cladding on the die surface can not only improve the die strength, but also reduce 2 / 3 of the manufacturing cost and 4 / 5 of the manufacturing cycle.

2. Prolong the service life of wear-resistant parts. The inner wall of oil cylinder is fatigue and abrasion failure, which makes it difficult to use normally. By using wear-resistant and corrosion-resistant alloy powder, laser cladding can restore its original size and meet the requirements of normal use. Through the modification characteristics of laser cladding, the surface wear resistance can be improved, its service life can be prolonged, the utilization rate of equipment can be improved, and the cost of enterprises can be reduced.

Professional technicians can ensure the control level of laser power, spot diameter and other important parameters in the cladding process. The size and specification control of the parts after cladding can reach 99.9% of the original parts. The workshop is equipped with high-speed cladding equipment, through high-speed nozzle powder layer by layer cladding to the surface of the damaged workpiece, and strictly in accordance with the drawings provided by the partner for turning and grinding, so that its high precision back to the non wear dimension standard

3. High efficiency. All kinds of roll wear failure in metallurgical industry, can not be used normally, through high temperature, high wear-resistant special powder processing, using laser cladding technology to restore the original size, so that it can be used normally, and can significantly extend its service life, reduce the replacement cycle, reduce enterprise maintenance and replacement costs, and reduce equipment downtime, to create greater benefits for enterprises. Wococarbide provides wear-resistant special powder. Search the website for details.

During the working process of general hydraulic cylinder in various industries, the cylinder block and piston rod are scrapped due to insufficient working pressure due to corrosion and wear failure. Through laser cladding remanufacturing repair, the service life can be increased by more than three times, the production and operation cost can be greatly reduced, the maintenance time can be saved, and the production benefit of the enterprise can be increased.

Materials for laser cladding

The widely used laser cladding materials mainly include: nickel base, cobalt base, iron base, titanium alloy, copper alloy, granular metal matrix composites, ceramic materials, etc.
