Cladding | Direct diode lasers (DDL)

 

Laser cladding is a method overlaying by supplying powder or wire of the same or different materials as the base material. By instantly melting the material with a laser and depositing it on the surface of the base material, it is used to improve the characteristics of the base material and repair parts. Laser cladding utilizing DDL forms a variety of cladding layer types with high-quality.

Advantages of laser cladding using DDL

High-quality cladding

 

*1 The dilution ratio is the percentage of the melted amount in the cladding layer. If the dilution ratio is high, the cladding material is likely to mix with the base material and this may diminish its material performance such as corrosion resistance, heat resistance, and wear resistance.

Low process cost

A variety of cladding types available

Focused beam pattern and profiles(example)

l_ddl_es7_xx

3D profile(example)

l_ddl_es10_xx

Effective for aluminum-base cladding
