Laser Cladding

Brief introduction:
The alloy powder is added into the laser melting pool by the synchronous powder feeding method, with small dilution rate of the cladding layer. The interface is in metallurgical bonding state, and is characterized by small workpiece deformation and small machining allowance. The cladding layer is free of porosity and crack defects with the hardness optional in HRC20-60, and has excellent wear resistance and corrosion resistance, which is suitable for the cladding manufacturing or re-manufacturing of various complex shape parts. The high-speed cladding efficiency can reach 40 minutes/m2 to realize the idea of "good steel is used on the blade"

After years of research and development of laser cladding technology, WISCO-HGlaser has deeply understood the processing requirements of various industries, and developed advanced technologies such as wide spot laser cladding, ultra-high speed laser cladding and inner hole laser cladding. It is suitable for the process requirements of different production lines of clients, effectively improving the product quality for clients and reducing the comprehensive operation cost.

Customer benefits:
Compared with the repair methods such as machining and manual arc welding, laser cladding has the characteristics of high reliability, outstanding processing efficiency, diversified process and low production cost.

Application area:
Currently, it is used in metallurgy, electric power, petroleum, chemical industry, ship, naval vessels, locomotive, coal machine, automobile and other industries, with stable and reliable product quality after cladding or re-manufacturing, lower cost and social effects.

Laser Quenching

Brief introduction: 
(HRC3-5). The high power density laser beam (104-105W/cm²) can enable that non-equilibrium rapid heating (105-106℃/s) and cooling (105℃/s) occur in the workpiece surface to achieve transformation hardening. The workpiece surface has no damage, small deformation, high hardness and good wear resistance (HRC3-5 is higher than that of traditional heat treatment).

Gustomer benefits: 
Good effect after processing/High productivity/High reliability/Processing environmental protection

Application area:
The equipment is widely used in mold, machinery manufacturing, petroleum, chemical industry, light industry, hardware tools, auto parts and other industries and typical workpieces include gear, corrugating roller, oil pipe, thread, auto mold, saw blade, guide rail, cylinder sleeve, important military products.

Laser Surface Alloying

Brief introduction: 
It is able to realize powder feeding alloying and prefabricated coating alloying. Alloy coating and substrate are fully metallurgical, forming a alloying layer without obvious interface, ensuring high bonding strength between alloying layer and substrate, and significantly improving surface wear resistance, corrosion resistance and high temperature resistance.

As a patented product of our company, the alloying coating is composed of ultra-fine ceramic aggregate, where the surface absorption efficiency is increased by more than 30%, and the hardness, wear resistance and high temperature resistance are significantly improved compared with the ordinary alloying coating.

Customer benefits: 
Good processing quality/High processing hardness/High reliability/High efficiency

Application area: 
At present, it is mainly applied in iron and steel metallurgy, chemical industry, light industry and other industries and can complete alloying processing for alloy cold roll, hot rolling roll (such as screw steel, section steel, slitting and other rollers), wood pulp screw, etc. with the surface micro-hardness of more than HV1000, the layer depth of 0.5mm, and the wear resistance increased by more than three times.

Laser Texturing

Brief introduction:
The laser beam with high energy and high repetition frequency is focused on the roller surface to form a micro molten pool; the micro convex concave body is formed under the action of side blowing gas and centrifugal force, and the texturing lattice with high hardness is obtained by ultra fast cooling. It can make the roller after texturing have a high surface hardness, a controllable shape, and a long service life and improve the production efficiency of the rolling mill. The random signal is used to change the morphology and arrangement of the textured points randomly, so that the surface is of disordered pitted surface structure.

Customer benefits: 
Low investment cost/Low operating costs/Good processing quality/High reliability

Application area: 
It is used in steel, aluminum, titanium and other industries. It can meet the needs of texturing processing of cold roller, and the texturing requirements of various work rolls such as temper mill, finisher, rolling mill and tandem mill.
