What is laser cladding

       

This article will introduce you laser
cladding from wococarbide. 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.
