Metallurgical Industry
In the field of metallurgical industry, we can improve the repair of worn and failed parts and help metallurgical enterprises reduce costs and increase efficiency.
Case: Laser cladding of rolling mill archway
Repair scope:
(1) Rolling line
1. Narrowband line 2. Medium and thick plate line 3. Thick plate line
(2) Parts
1. The assembly surface of the rolling mill slide plate (including the elevation and the bottom surface) 2. The assembly surface of the frame roller 3. The position of the lock door plate 4. The bolt holes at each position 5. Other damaged parts
Aerospace
Improve aviation engine maintenance capabilities, reduce operating costs, and promote high-quality development of the aviation industry.
Case: Laser cladding of single crystal blades
Technical achievements:
1. The maximum single-pass cladding width is 1.8mm, and the continuous stacking can reach a height of 10mm;
2. The single-layer thickness can be adjusted within the range of 0.15~0.5mm;
3. The amount of miscellaneous crystals on both sides is less than 10%;
4. The high-temperature tensile performance of the bonding interface at 800°C reaches 91% of that of the base material, and the strength of the cladding layer is not less than 91% of that of the base material.

Hydropower industry
In the resource-rich hydropower field, we should repair and strengthen current-flowing components with “low energy consumption and no pollution” to promote the technological upgrading of hydropower equipment.
Thermoelectricity industry
On-site repair on large turbine generator sets eliminates the need for disassembly and assembly, improves electrical conductivity, and ensures stability, reliability, and long service life.
Mold making
A full metallurgical bonding coating is melted on the glass mold that is frequently cooled and heated rapidly. The mold is wear-resistant, corrosion-resistant, and resistant to high-temperature fatigue.
Case: Glass mold joint surface cladding
Technical process: The joint surface of the glass mold is prone to wear, corrosion, thermal fatigue cracks, oxidation, etc. during use, leading to mold failure. Using laser cladding technology instead of plasma surfacing to repair the seam line of the glass mold has great advantages in terms of efficiency, cost, and technical effects.
Petrochemical
On petrochemical equipment with harsh operating environments, a dense protective film is formed on the surface of the workpiece to increase surface roughness, maintain smoothness, and improve wear resistance.
Case: Cladding of inner holes of oil drilling tools
Technical process: The inner circular surface of the oil drilling tool sleeve is eroded by mud and will quickly wear out and fail. Conventional repair and strengthening methods make it difficult to truly extend the service life of parts. The use of deep-hole laser cladding to repair and strengthen the eroded parts of the inner wall can not only restore the original dimensions of the parts but also greatly improve the service life of the parts.
Construction machinery
In the field of construction machinery, the traditional hard chromium electroplating process is replaced by a green manufacturing process that is environmentally friendly and pollution-free and helps supply-side structural reform.
Case: drive shaft (crankshaft) cladding
Process technology: Contact surface wear of transmission components during use is a common failure form. Laser cladding repair is used to repair the heat-affected zone with small residual stress. The process window is strictly controlled, and the mechanical properties after repair reach or exceed the original performance.
