​​       Data @2025. April

• Giantree Laser has an internal laboratory facility  to support the Quality and R&D activities. For specialized laser cladding applications, we can develop customized solutions based on different base and cladding material combinations. 

• Our Quality Management System is certified in accordance with the ISO 9001:2015 on Provision of Laser Cladding, Repairing and related Machining Services.

Laser cladding utilizes precise laser as heat source to deposit a thin layer of desired metal on a substrate.

Typical coating materials form: powder and wire.

Suitable coating alloys with right merphology and size:

• Fe based stainless steel

• Ni based

• Co based

• Metal carbide composites

• Cu based

• Other metals

Suitable substrate: carbon steel, stainless steel and other alloys.

More resistant to impact: metallurgy bonding

More corrosion resistant: pore free, fully dense

More stable: a high degree of automation, quality control

Applicability: small thermal effect, substrate deformation small, low dilution rate (1-5%)
